Abstract

The automatic identification of interchangeable torch components, such as consumables, for welding and cutting torches includes the addition of one or more passive markings to the surface of an interchangeable torch component. Therefore, automatic identification can be performed by a torch assembly including a torch body and one or more imaging devices, or a system including the torch assembly and a power supply. The torch body has an operating end configured to removablely receive one or more interchangeable torch components, including one or more passive markings.One or more imaging devices are positioned to optically acquire an image or image data representative of one or more passive markings included on one or more interchangeable torch components so that one or more interchangeable torch components can be automatically identified based on one or more passive markings. Consequently, multiple components can be reliably and consistently identified.

Description

1 / 40 Plasma torch assembly, system and method for identifying interchangeable plasma torch components. TECHNICAL FIELD

[001] This description is intended to identify components for welding and cutting torches and, in particular, to automatically identify interchangeable torch components, such as consumable components, for welding and / or cutting torches. BACKGROUND

[002] Many welding and cutting torches, such as plasma cutting torches, now include torch bodies that can accommodate a variety of consumables (e.g., welding tips, cutting tips, and / or a variety of electrodes), as well as other interchangeable torch components. Consequently, a single torch body may be capable of being used for a variety of cutting and / or welding operations (with different tips, electrodes, and / or other interchangeable components / consumables being installed for different operations). Unfortunately, different interchangeable torch components (e.g., different torch tips and different electrodes) often require different operating configurations. Thus, different interchangeable torch components (e.g., torch tips and / or electrodes) must be identified before or during installation on the torch body (or at least before torch operation).In addition, a power supply connected to the torch body usually needs to be adjusted when the torch is used with different components.

[003] Frequently, different consumable components of the torch (e.g., torch tips, electrodes, etc.) are Petition 870260075450, dated 07 / 29 / 2026, page 5 / 104 2 / 40 identified by an operator before the installation of a particular torch component in a torch body. For example, an operator might scan a barcode included on a component or on the packaging for the component. Unfortunately, visual identification is often difficult (if not impossible), especially for inexperienced users, and barcode identification is only possible when the end user is carrying a barcode reader. It can also be difficult to identify counterfeit or unsuitable consumable components (e.g., competing components with characteristics that are not suitable for providing ideal welding / cutting parameters with a specific torch body, for example, because the parts include altered geometries) with visual or barcode identification.

[004] Alternatively, some components can be identified using radio frequency identification (RFID) techniques, pressure drop measurement techniques, and / or surface reflectivity measurement techniques. Unfortunately, RFID identification techniques can be expensive and may be incompatible with older parts unless the older parts are retrofitted with an RFID tag (making the technique even more expensive). However, identifying components by measuring pressure drop or reflectivity may be unreliable and / or impractical for quickly identifying interchangeable torch components (i.e., torch tips and / or electrodes) as they are installed in a torch body. For example, pressure drop measurements may only be able to identify a component after a substantial period of time, and furthermore, pressure drop measurement for a consumable may be inaccurate if the consumable is worn.Meanwhile, measuring the reflectivity of a component may not be reliable, as reflective measurements can be. Petition 870260075450, dated 07 / 29 / 2026, p. 6 / 104 3 / 40 inconsistent, especially for components of different shapes.

[005] Regardless of how interchangeable torch components are identified, the power supply usually needs to be manually adjusted to the appropriate settings before a torch with a newly installed component can be safely used. In some cases, a user must consult industry literature (i.e., manuals) or the component packaging to determine the appropriate settings, which can become quite tedious or confusing, especially for an inexperienced user. If, instead, a user adjusts the settings based on memory or fails to adjust the settings while switching between consumable components, the torch may become unsafe to operate.Furthermore, or alternatively, the torch may operate under non-ideal conditions, which can negatively affect the torch's cutting / welding performance and / or reduce the workpiece's lifespan, each potentially leading to inefficiencies in welding / cutting operations, both in terms of time and cost.

[006] In view of the foregoing, it is desirable to quickly and automatically identify a torch component installed in a torch (i.e., an electrode, torch tip, protective cup, gas distributor or any other interchangeable / consumable part) with accuracy and reliability. Furthermore, it is desirable to automatically adjust cutting or welding parameters, such as power parameters, flow parameters and / or fault conditions, based on the automatic identification. SUMMARY

[007] This disclosure is directed to the automatic identification of components, such as consumable components, for welding and cutting torches. According to one embodiment, a set Petition 870260075450, dated 07 / 29 / 2026, p. 7 / 104 4 / 40 of torches for welding or cutting operations includes a torch body and one or more imaging devices. The torch body has an operating end configured to removablely receive one or more interchangeable torch components, including one or more markings, and defines an internal cavity. One or more imaging devices are disposed within the internal cavity and are positioned to optically acquire an image or image data representative of one or more markings included on the one or more interchangeable torch components so that the one or more interchangeable torch components can be automatically identified based on the one or more markings. Consequently, various components can be reliably and consistently identified using the techniques presented here.

[008] Furthermore, one or more markings (e.g., indentation or indentations) can be created with relatively inexpensive techniques, especially compared with various other part identification solutions, such as RFID tags; thus, older parts can be easily and economically adapted to be suitable for the identification techniques presented here. In addition, as one or more markings can be or include a trademark, counterfeit or non-compliant parts can be easily identified (since counterfeit parts would not include, or at least should not include, the trademark). This reduces the safety risks and performance degradation associated with counterfeit and / or non-compliant parts. In at least some embodiments, one or more markings are passive mechanical markings.

[009] In some embodiments, the operating parameters of a torch, including the component (e.g., power parameters of the energy supplied to the torch), are automatically adjusted in response to automatic identification. For example, the source Petition 870260075450, dated 07 / 29 / 2026, page 8 / 104 The 5 / 40 power supply can automatically adjust the current level supplied to the torch. Additionally, or alternatively, the power supply can automatically adjust the gas flow settings. Furthermore, an indication of operating parameters (e.g., current regulation) or a warning of unsafe conditions can be displayed on the power supply. Among other advantages, the automatic adjustment of the torch's operating parameters based on automatic identification allows a user to seamlessly transition from one cutting or welding operation to another.

[010] For example, a user can seamlessly transition from cutting at 40 Amps with a first plasma cutting tip to cutting at 80 Amps with a second plasma cutting tip simply by changing various consumable components. As another example, a user can seamlessly transition from marking to cutting to chiseling, etc., by changing consumable components. Furthermore, and also advantageously, automatic adjustment of operating parameters can prevent a user from inadvertently or unintentionally increasing or decreasing certain operating settings based on the consumable components currently installed in the torch. For example, the power supply can restrict the current supplied to a specific upper limit based on the identity of a component or component identities currently installed in / on the torch.By preventing a user from unintentionally altering certain operating settings, this can discourage or prevent unsafe welding / cutting operations, while also discouraging or preventing a user from cutting or welding with suboptimal operating settings. In turn, these adjustments / restrictions can decrease the costs associated with a [unclear / incomplete sentence - likely related to welding / cutting operations]. Petition 870260075450, dated 07 / 29 / 2026, page 9 / 104 6 / 40 cutting / welding operation (i.e., avoiding errors and / or shortening the duration of operations) and reduce the costs associated with cutting / welding operations over time, such as maintenance or spare parts costs (i.e., increasing the lifespan of the torch, power source and / or torch components).

[011] Furthermore, if an operator obtains counterfeit or unsuitable consumable components (e.g., components with characteristics that are not suitable for providing ideal welding / cutting parameters with a specific torch body), the techniques presented here can either prevent the operator from initiating torch operations (i.e., prevent arc transfer) or apply limits to the torch's operating parameters. Limiting the torch's operating parameters can protect the operator and / or the torch from hazards that could potentially be caused by the failure of a counterfeit or unsuitable consumable component.

[012] According to another embodiment, a system includes a torch assembly and a power supply. The torch includes a torch body with an operating end that receives an interchangeable torch component with one or more passive, mechanical markings and an imaging device that is disposed on or within the torch body and optically acquires an image or image data representative of the one or more passive, mechanical markings included in the interchangeable torch component. The power supply automatically adjusts the operating parameters of the torch based on the one or more passive mechanical markings.

[013] According to yet another embodiment, automatic component identification is performed by a method that includes visual or optical acquisition of an image or image-representative data (e.g., image capture) of one or more markings Petition 870260075450, dated 07 / 29 / 2026, p. 10 / 104 7 / 40 passive markings are included in or within one or more interchangeable torch components installed in or within a torch or torch assembly when operating one or more imaging devices disposed within or on the torch body. One or more interchangeable torch components are identified based on one or more passive markings. BRIEF DESCRIPTION OF THE VARIOUS VIEWS OF THE DRAWINGS

[023] A method, apparatus and system for automatically identifying interchangeable torch components, such as electrodes, torch tips and other consumables, for welding and / or cutting torch assemblies (hereinafter referred to simply as torch assemblies) are presented herein. The method, apparatus and system identify interchangeable torch components using optical recognition techniques that identify one or more markings (e.g., one or more passive mechanical markings) included on the interchangeable torch components.For example, an imaging device, such as a camera, may be included within or on the torch assembly, and the imaging device may be positioned to optically acquire an image and / or image data representative of a surface (e.g., a back surface) of one or more consumable components or a set of components (e.g., a usable and / or non-usable cartridge consisting of said components) installed on / within the torch of the torch assembly. As two specific examples, a camera may acquire (e.g., capture) an image of a marking, or a laser scanner may acquire image data representative of a marking. Petition 870260075450, dated 07 / 29 / 2026, p. 12 / 104 9 / 40

[024] Regardless of how the images and / or image data are acquired, optical recognition techniques (e.g., optical character recognition (OCR) techniques) can be applied to the acquired image and / or image data to recognize one or more markings included in the image and / or image data. In some embodiments, one or more markings included on the interchangeable torch components may include a manufacturer's trademark (e.g., ESAB) that allows the components to be recognized as a genuine (i.e., not counterfeit) component. In addition, or alternatively, one or more markings may include an indication of the operation(s) for which the component is intended (e.g., 60A CUT).

[025] As explained in more detail below, in at least some embodiments, a power supply coupled to a torch that receives interchangeable torch components can automatically adjust or control the torch's operating parameters when one or more interchangeable components included / installed in the torch are identified. For example, in some embodiments, the torch can be configured to emit light towards a surface of a torch component, including one or more markings, optically acquire an image and / or image data representative of one or more markings, and transmit the image to a power supply. The power supply can then identify the component and automatically adjust the power and gas transfer settings accordingly. The delegation of operations in this specific example can make the techniques presented here relatively easy to adapt to existing torches.Delegating operations can also, in some implementations, reduce the amount of processing (and the... Petition 870260075450, dated 07 / 29 / 2026, p. 13 / 104 10 / 40 number of components) required in the torch, which can make the torch easier to service, lighter (at least progressively) and / or easier to operate. Furthermore, identifying the component in the power supply can allow the power supply to quickly adjust the energy and / or gas parameters being delivered to the torch based on the components installed in the torch, which can ensure that the torch cannot operate with unsafe or undesirable energy parameters (i.e., undesirable for welding / cutting performance and / or for the longevity of the torch and / or the identified interchangeable torch components).That being said, in other embodiments, a torch can include any necessary components, allowing interchangeable torch components to be identified on the torch (and instructions to be sent to the power source accordingly), as is also explained in more detail below.

[026] FIGURE 1A illustrates an exemplary embodiment of the cutting system 10 that can implement the techniques presented herein. At a high level, the cutting system 10 includes a power supply 40 that is configured to supply (or at least control the supply of) power and gas to a torch assembly 20 which includes a torch 22. As described in more detail below, the power supply 40 supplies gas and / or power to the torch assembly 20 based on the identity of the interchangeable components installed in the torch assembly 20. The cutting system 10 also includes a working cable 50 with a grounding clamp. Although the conductor cable 50 and the conductor cable 32 included in the torch assembly 20 (see FIGURE 1B) are illustrated as being relatively short, the conductor cables can be of any length. Although not shown, a welding system Petition 870260075450, dated 07 / 29 / 2026, page 14 / 104 An 11 / 40 configuration designed to implement the techniques presented here may include similar components.

[027] FIGURE 1B illustrates the torch assembly 20 shown in FIGURE 1A from an external perspective. As can be seen, the torch assembly 20 includes a torch 22 with a torch body 100 extending from a first end 101 (e.g., a connecting end 101) to a second end 102 (e.g., an operating or operative end 102). The connecting end 101 of the torch body 100 can be coupled (in any manner now known or hereafter developed) to one end of the conductor cable 24, and the other end of the conductor cable 24 can be coupled to or include a connector 26 that allows the torch assembly 20 to be coupled to the power source 40 in any manner now known or hereafter developed (e.g., a releaseable connection).Meanwhile, the operating end 102 of the torch body can receive interchangeable components, such as consumable components, which are generally indicated by item 200, but may include a variety of components such as torch tips, electrodes, gas rings, etc., as discussed in more detail below. The body 100 may also include a trigger 105 that allows the user to initiate cutting operations.

[028] FIGURE 1C illustrates a part of the torch 22 that is close to the operating end 102 of the torch body 100. For simplicity, FIGURE 1C illustrates the torch body 100 without several components or parts, such as energy or gas transfer components, which are normally included in a welding / cutting torch. Instead, FIGURE 1C illustrates only selected components or parts that allow a clear and concise illustration of the techniques presented herein. However, it should be Petition 870260075450, dated 07 / 29 / 2026, page 15 / 104 12 / 40 It is understood that any components not illustrated that are typically included in a torch (i.e., components to facilitate welding or cutting operations) may (and, in fact, should) be included in a torch configured according to an exemplary embodiment of the present invention.

[029] In the embodiment shown, the torch body 100 receives an interchangeable electrode 120, an interchangeable gas distributor 130, an interchangeable torch tip 140, and an interchangeable protective cap 150, insofar as each of these components can be interchanged with other similar components and is not necessarily interchangeable or reconfigurable in itself. For example, the electrode 120 is interchangeable because it can be exchanged or replaced with another electrode (or other similar consumable). In the embodiment shown, the gas distributor 130 and the electrode 120 can be installed in the torch body 100 and the tip 140 can be installed on top. Alternatively, electrode 120, gas distributor 130 and tip 140 can be installed in the torch body 100 as a single component (e.g., as a cartridge).In any case, once the electrode 120, the gas distributor 130, and the tip 140 are installed on / inside the torch body 100, the protective cup 150 is installed around an installation flange 142 of the torch tip 140 to secure the electrode 120, the gas distributor 130, and the torch tip 140 in place on (and in axial alignment with) an operating end 102 of the torch body 100.

[030] However, in other embodiments, the electrode 120, gas distributor 130, and / or torch tip 140 (as well as any other interchangeable torch components) may be attached or affixed to the torch body 100 in any desirable manner, such as by mating threaded sections included in the torch body 100 with corresponding threads included in the Petition 870260075450, dated 07 / 29 / 2026, page 16 / 104 13 / 40 components. In addition, in other embodiments, the torch assembly 20 (or just the torch 22) may include any suitable combination of interchangeable torch components, in addition to or instead of the interchangeable electrode 120, the interchangeable gas distributor 130, the interchangeable torch tip 140 and / or the interchangeable protective cup 150.

[031] Still referring to FIGURE 1C, the torch assembly also includes an imaging device 160 which, in the embodiment shown, is disposed within the torch body 100. More specifically, the torch body 100 defines an interior cavity 104 and the imaging device 160 is positioned within the interior cavity 104 so that the imaging device 160 can optically acquire one or more images and / or image data representative of the operating end 102 of the torch body. 100. That is, the imaging device 160 is positioned to optically acquire one or more representative images and / or image data of the interchangeable torch components installed on the operating end 102 of the torch body 100. In some embodiments, the imaging device 160 does not need to have a direct line of sight to the operating end 102 and instead can view the operating end 102 from the internal cavity 104 by means of any optical components, such as mirrors, optical fiber, light tubes, etc., now known or developed hereafter. In other words, the imaging device 160 can be optically coupled to the operating end 102 of the internal cavity 104 by means of any optical components now known or developed hereafter.In fact, in some embodiments, the imaging device 160 does not need to be disposed within the torch assembly 20 and can be disposed on or near an exterior surface of the torch body 100 and optically coupled to it. Petition 870260075450, dated 07 / 29 / 2026, page 17 / 104 14 / 40 operating end 102 of the inner cavity 104. That said, embodiments with an internal imaging device 160 (i.e., an imaging device 160 disposed within the inner cavity 104) may be thinner, more efficient and less likely to fail than embodiments including an imaging device coupled to an outer surface of the torch body 100 or otherwise disposed externally to the torch assembly 20 (e.g., an external imaging device 160).

[032] Generally, the imaging device 160 can be any device or component capable of optically acquiring two-dimensional and / or three-dimensional images and / or image data representative of an image. For example, the imaging device 160 can be a single camera that captures two-dimensional images of any surfaces (and one or more markings included) in its field of view. Additionally or alternatively, the imaging device 160 can include multiple imaging components, such as a camera array, multiple cameras, lasers, LIDAR, ultrasound, sonar, radar, infrared imaging device, etc., which allow the imaging device 160 to acquire two three-dimensional images, three-dimensional images (e.g., to detect engravings, as described in more detail below) and / or image data (e.g., data from an optical scan with a laser representative of an image).

[033] As illustrated in FIGURE 1C, in some embodiments, the imaging device 160 may have a field of view A that covers only a part (e.g., half) of the operating end 102 of the torch body 100, but in other embodiments, the imaging device 160 may have a field of view that covers the entire torch body 100 (A + B). As explained in more detail below, in some embodiments, the components Petition 870260075450, dated 07 / 29 / 2026, page 18 / 104 Interchangeable 15 / 40 torch parts (e.g., consumable components) can be keyed to align any markings with a certain radial location on the torch body (e.g., a top of the torch body). In these embodiments, it may be necessary for the imaging device 160 to have a field of view A that covers the radial location (e.g., it only has a field of view that covers a segment of the cylindrical torch body 100).

[034] Furthermore, in some embodiments, the various components may include pathways, openings, or other features (e.g., embedded optical fibers) to expand the field of view of an imaging device 160 beyond the components that are immediately adjacent to the imaging device 160. For example, in FIGURE 1C the imaging device 160 has a direct line of sight to a rear surface 122 of the electrode 120 and a rear surface 132 of the gas distributor 130, but the imaging device 160 may not have a direct line of sight to a rear surface 144 of the torch tip 140. Thus, the gas distributor 130 defines a pathway 134 (e.g., an optical fiber pathway) that provides the imaging device 160 with a line of sight to a specific part of the rear surface 144 of the torch tip.Consequently, in the embodiment depicted, the imaging device is positioned to optically acquire one or more images and / or image data representative of the posterior surface 122 of the electrode 120, the posterior surface 132 of the gas distributor 130 and the posterior surface 144 of the torch tip 140, regardless of whether the imaging device 160 has a field of view defined by A or defined by A + B.

[035] In some embodiments, the torch assembly 20 may also include a light source 170 configured to illuminate a field of view (e.g., A or A+B) of the imaging device. Petition 870260075450, dated 07 / 29 / 2026, p. 19 / 104 16 / 40 160. That is, if the imaging device 160 has a field of view A, the light source 170 can illuminate at least the field of view A, as illustrated by A1, and if the imaging device 160 has a field of view A + B, the light source 170 can illuminate at least the field of view A + B, as illustrated by A1 + B1. The light source 170 can be any device that can illuminate interchangeable torch component surfaces in a particular field of view, such as a light-emitting diode (LED). Additionally or alternatively, the light emitted during torch operations (i.e., light emitted by a plasma arc) can supplement or replace the light from the light source 170 included within or on the torch body 100, and thus the welding / cutting operations can also be referred to as the light source 170.If the torch assembly 20 includes a light source 170, the light source can be positioned within the internal cavity 104 of the torch body 100 and can be optically coupled to the operable end of the internal cavity 104 by means of any optical components, such as mirrors, optical fiber, light tubes, etc., now known or developed hereafter.

[036] Although FIGURE 1C illustrates a single imaging device 160 and a single light source 170, in some embodiments, the torch 20 may include several imaging devices 160, each dedicated to a specific type of interchangeable torch component 200 (e.g., a first imaging device for electrodes, a second imaging device for torch tips, etc.). In other embodiments, a single imaging device 160 may be suitable for generating images of one or more markings 210 (see FIGURE 2) included in any components 200 installed in the torch body 100. Embodiments including multiple imaging devices 160 may also include multiple light sources 170. The light sources 170 may each be dedicated Petition 870260075450, dated 07 / 29 / 2026, p. 20 / 104 17 / 40 to a single imaging device 160, a set of imaging devices 160, or some combination thereof. Alternatively, a single light source 170 may provide light for any imaging devices 160 included in a flashlight 20.

[037] With reference to FIGURE 1C, the torch assembly also includes a processor 190. The processor 190 included in the torch body 100 can operate any combination of imaging devices 160 and light sources 170. Furthermore, as described in more detail below, the processor 190 can identify components based on one or more of their markings or transmit data to the power supply that allows the power supply to identify the components based on one or more of their markings.Thus, regardless of how the interchangeable electrode 120, the interchangeable gas distributor 130, the interchangeable torch tip 140, and / or the interchangeable protective cup 150 are connected to the operating end 102 of the torch body 100, if any of these interchangeable torch components (as well as any other interchangeable torch component included within or on the torch body 100) includes one or more markings 210 (see FIGURE 2), the component can be identified based on one or more images and / or image data representative of one or more markings 210 acquired by the imaging device 160 (with the acquisition of images and / or image data potentially facilitated by the illumination of the light source 170).

[038] FIGURE 2 provides a block diagram representation of the torch of FIGURE 1C.Consequently, similar parts in FIGURE 1C are labeled with the same part numbers in FIGURE 2 (and the description of those parts included above may be applicable to similar parts shown in FIGURE 2). For example, the description of torch body 100 included above may be applicable. Petition 870260075450, dated 07 / 29 / 2026, p. 21 / 104 18 / 40 to the torch body 100 shown in FIGURE 2, and thus the torch body 100 can receive an interchangeable consumable component 200 (which can be representative of the electrode 120, gas distributor 130, torch tip 140, or protective cup 150) with one or more markings 210. For simplicity, the markings 210 can also be referred to here as indicators 210, with the understanding that the term indicators can refer to one or more markings despite indicators being plural. In FIGURE 2, the indicators 210 are included on a rear surface 202 of the component 200; however, it is to be understood that this location is only an example.In other embodiments, any interchangeable torch component 200 that is capable of being installed in the torch body 100 (including interchangeable torch components shown in FIGURE 1C, as well as any other interchangeable torch components not shown in FIGURE 1C, such as various consumables) may include indications 210 in any location that are visible by the imaging device 160 (either directly or through optical components).

[039] Generally, an interchangeable torch component 200 may be manufactured with indications 210 included therein, or indications 210 may be added to a surface of the component in any manner now known or hereafter developed. For example, indications 210 may be permanently added to an interchangeable torch component (e.g., a consumable) by permanently marking the torch component with characters and / or symbols (e.g., with a laser, engraving, printing, stamping, etc.). Alternatively, indications may be permanently or temporarily added to an interchangeable torch component (e.g., a consumable) with a label, sticker, or other such item / method. The characters and / or symbols Petition 870260075450, dated 07 / 29 / 2026, page 22 / 104 19 / 40 of the markings 210 correspond to the manufacturer and application of the component (e.g., purpose, use, and characteristics). For example, in FIGURE 2, the interchangeable component 200 (represented as the electrode 120, the gas distributor 130, the torch tip 140, or the protective cup 150) includes the markings 210 indicating ESAB 60A GOUGE. This indicates that the part was manufactured by ESAB (and therefore may be suitable for an ESAB torch body) and is suitable for plasma chiseling with 60 Amps.However, despite this example, the characters and / or symbols included in the clues 210 do not need to be human-readable (marks that are not human-readable may be referred to here as machine-readable), provided that the imaging device 160 can optically acquire one or more images and / or image data representative of the clues 210 (even if the acquisition requires illumination from a light source 170) and that optical recognition techniques can be applied to the characters, symbols, or any other identifier / clue.

[040] 210 clues need not be two-dimensional and instead, 210 clues may be or include three-dimensional features. For example, 210 clues may include a raised or carved part. Three-dimensional features may be scanned for symbols and characters, as well as profile and depth (e.g., with a laser, sonar, radar, etc.) and profile and depth may be considered when the clues are processed with optical recognition techniques. However, the clues are passive mechanical clues, insofar as passive indicates that the clues do not emit any signal, store or transmit electronic data, or perform any actions. In other words, the clues / markings are mute (as opposed to being intelligent clues that can interact with a device of Petition 870260075450, dated 07 / 29 / 2026, page 23 / 104 20 / 40 computing). However, mechanical indicates that the markings / indications are physical markings formed or created from additive or subtractive physical processes applied to an interchangeable component. As some examples, mechanical markings may include holes formed with drills, letters engraved on a material, symbols printed on a material, shapes etched onto a material, etc. In at least some embodiments, the markings are also non-functional insofar as the markings provide a point of attachment, a cooling feature, and / or some other functional aspect of an interchangeable component and are instead provided on the interchangeable component in addition to the functional features.

[041] Regardless of the physical characteristics of the indications (for example, whether the indications are two-dimensional or three-dimensional, include holes or engraved shapes, etc.), the indications 210 (for example, one or more markings) are included in a part of an interchangeable component 200 that will be within a field of view of one or more imaging devices included in the torch assembly (for example, field of view A of FIGURE 1C). That is, the indications 210 are provided in a location that is optically visible from a position inside the operating end 102 of the torch 22 (see FIGURE 1C). For example, in at least some embodiments, the indications 210 may be included in a radially external position on a rear surface (for example, an end wall, as opposed to a side wall) of a consumable component.In at least some embodiments, this position is unobstructed (i.e., not covered or blocked by other components) and is thus optically visible by one or more imaging devices 160 included in the torch assembly. Petition 870260075450, dated 07 / 29 / 2026, p. 24 / 104 21 / 40

[042] In comparison, typically interchangeable components (e.g., consumable components) include brand information (or other markings) on a larger surface (e.g., a side wall) of the component, where it is easier to include the brand information (e.g., there is more surface area available to include the information). In addition, typically, interchangeable components (e.g., consumable components) include mechanical coupling features (e.g., threading, cooling passages / connections, etc.) on a back wall, and therefore it is difficult to include a marking on a back wall (or other optically visible parts of the component).Here, one or more interchangeable components are marked on an optically visible surface to ensure that one or more imaging devices included in the torch assembly can acquire an image and / or image data from one or more markings included on one or more interchangeable components. For example, in FIGURE 1C, the electrode 120 may include one or more markings on its rear surface 122, which may be an optically visible surface insofar as the surface may be visible from the operating end 102 of the torch body 100 (of the torch 22).

[043] Furthermore, regardless of the physical characteristics of the indicators, in at least some embodiments, component 200 includes features that align the indicators 210 with a specific part of the torch body 100. In these embodiments, the alignment ensures that the indicators 210 are viewable by the imaging device 160 included in the torch body 100. For example, component 200 and the torch body 100 may include markings (or any other type of mechanical keying) that indicate how to align component 200 with the torch body 100. Petition 870260075450, dated 07 / 29 / 2026, page 25 / 104 22 / 40 during the installation of component 200 in the torch body 100 to ensure that the indicators 210 will be optically aligned with the imaging device 160.

[044] Furthermore, although FIGURE 2 illustrates only a single component 200 with the indicators 210, one or more interchangeable torch components 200 may be installed on a torch body 100 and the torch 20 may be configured to detect each of these components 200. In some embodiments, multiple components may be associated with a single marking or set of markings 210 (for example, if multiple components are combined in a cartridge) and one or more markings 210 may be specific to the component combination. For example, several components may comprise part of an overall indicator pattern and the overall indicator pattern may be complete only when all components are connected to each other.As another example, a cartridge body may include one or more markings and may be configured to receive only specific consumable components (and one or more markings may represent all components in the cartridge body). Alternatively, multiple components may each include their own 210 markings. In embodiments where multiple components include their own 210 markings, the 210 markings may be compared between components to determine component compatibility. As mentioned, in some embodiments, the torch 20 may include several imaging devices, each dedicated to a specific type of interchangeable torch component 200 (e.g., a first imaging device for electrodes, a second imaging device for torch tips, etc.), however, in other embodiments, a single imaging device 160 may be suitable for the imaging markings 210 included in any. Petition 870260075450, dated 07 / 29 / 2026, page 26 / 104 23 / 40 components 200 installed in the torch body 100.

[045] As mentioned above (and explained in detail below), the processor 190 can be configured to process an image 162 (or image data) acquired by the imaging device 160 (instead of simply being configured to operate one or more imaging devices 160 and one or more light sources 170). For example, in FIGURE 2, the processor can apply OCR techniques to the image 162 (which includes characters that provide ESAB 60A GOUGE). However, in various embodiments, any optical recognition techniques, now known or developed hereafter, can be applied to an image 162 acquired by the imaging device 160. Similarly, any optical techniques now known or developed hereafter can be applied to the acquired image data to identify markings from the data (for example, to join data from an optical scan and subsequently identify markings with optical recognition techniques).Generally, optical recognition techniques may involve comparing an acquired image and / or image data with a library of data and / or images to try to find a match.

[046] Returning now to FIGURE 3, this figure represents a high-level block diagram of a system 300 (e.g., cutting system 10) configured according to the present invention. The system 300 includes a torch assembly 301 (such as the torch assembly 20 shown in FIGURES 1A-C) and a power supply 350 (such as the power supply 40 shown in FIGURE 1A) which is configured to adjust operating parameters, such as power parameters or gas flow settings, of a welding or cutting operation. As described above in relation to FIGURE 1C, the torch assembly 301 can Petition 870260075450, dated 07 / 29 / 2026, page 27 / 104 24 / 40 selectively receive interchangeable torch tips and electrodes, among other interchangeable torch components. Consequently, tips 1 to 3 and electrodes 1 to 3 are shown in dashed lines, as possibly being installed on the operating end 102 of the torch 30. As described above, the torch assembly 301 may also include a processor 190. Additionally, the torch assembly 301 may include a memory 310 and an interface 330 that provides a connection to an interface 370 included in the power supply 350. In some embodiments, the interface 330 included in the torch assembly 301 may provide a power and data connection to the power supply 350 (i.e., via separate transmission cables).For example, each interface 330 may include a wireless interface unit and a power interface unit, with the wireless interface unit enabling wireless data transfer between the torch assembly 301 and the power supply 350, and the power interface unit enabling wired power transfer from the power supply 350 to the torch 30.

[047] Generally, the processor 190 (e.g., a microprocessor) can execute instructions contained in memory 310 (i.e., image logic 312) to operate various components included in or coupled to it, such as one or more image devices 160 and one or more light sources 170. In some embodiments, the processor 190 can also execute image logic 312 to determine whether the required / necessary parts are in place within / on the torch assembly 301, as discussed in more detail below. Furthermore, in some embodiments, the processor 190 can execute identification (ID) logic 314 to identify a component installed therein (i.e., electrode 1 to 3 or tip 1 to 3), as briefly discussed above. Additionally, the processor 190 Petition 870260075450, dated 07 / 29 / 2026, page 28 / 104 25 / 40 can execute instructions contained in memory 310 (i.e., image logic 312) to send data and / or instructions to the power supply 350. The processor's operations when executing image logic are discussed in more detail below in relation to FIGURE 4.

[048] However, the power supply 350 may also include a processor 354 configured to execute instructions stored in its memory 360 (i.e., operational logic 362 and ID identification logic 314). An image ID data structure 364 (i.e., a table) that correlates data received from the torch assembly 301 with component identities and / or one or more operational parameters may also be stored in the memory 360 of the power supply 350. Alternatively, the image ID data structure 364 may be stored in an external ID database 380 that can be accessed by the power supply 350 and / or torch assembly 301 (i.e., through a network interface unit included in interface 370 and / or interface 330, respectively).As described in greater detail below in relation to FIGURES 5 and 6, in at least some embodiments, the power supply processor 354 can execute identification logic 314 to correlate data received from the torch assembly 301 with a component identity (from image IDs 364) to identify an installed component.

[049] Additionally or alternatively, the power supply processor 354 can execute the operational logic 362 to adjust the operational parameters of a welding or cutting operation while an identified component is placed in the torch. In at least some embodiments, the operational parameters may include automated cutting / welding settings (e.g., settings controlled by a numerical control controller). Petition 870260075450, dated 07 / 29 / 2026, page 29 / 104 26 / 40 computerized (CNC)), power / current settings and / or gas flow settings. As some examples, automated cutting / welding settings include travel speed, piercing height, lift height / cutting height and / or piercing dwell time. By comparison, gas flow settings, in at least some embodiments, may include the type of gas being used (e.g., oxygen, nitrogen, argon, air, etc.), a pressure or flow rate, gas function (e.g., pre-flow and post-flow, gas cutting, shielding gas, etc.) and / or gas sequencing. In some embodiments, the power supply processor 354 may also execute operational logic 362 to determine whether the required / necessary parts are placed within / on the torch assembly 301 (e.g., instead of processor 190 executing image logic 312 to make this determination), as is discussed in more detail below.

[050] Furthermore, although not shown, in some embodiments, the power supply interface 370 and / or the torch assembly interface 330 may allow a connection (wired or wireless) to one or more external computing devices and the external computing device(s) may include identification logic 314 and / or operational logic 362 such that the external computing device may analyze an image or image data and communicate with the power supply 350 and / or torch assembly 301, adjust the operational settings of the power supply 350 or otherwise execute logic associated with at least a part of the techniques presented herein.

[051] Generally, memory 310 and memory 360 included in torch assembly 301 and power supply 350, respectively, can be configured to store data, including instructions relating to the operation of various components or any other data. Petition 870260075450, dated 07 / 29 / 2026, p. 30 / 104 27 / 40 Furthermore, 310 memory and 360 memory may include read-only memory (ROM), random access memory (RAM), magnetic disk storage media devices, optical storage media devices, flash memory devices, electrical, optical, or other physical / tangible (e.g., non-transient) memory storage devices. Thus, in general, 310 memory and 360 memory may be or include one or more computer-readable (non-transient) storage media (e.g., a memory device) encoded with software comprising computer-executable instructions.For example, memory 310 and / or memory 360 may store instructions that can be executed by their associated processor (processor 190 and processor 354, respectively) to automatically identify a component installed inside / on a torch of torch assembly 301 and / or to automatically adjust operating parameters in response to automatic identification, as described herein. In other words, memory 310 and / or memory 360 may include instructions that, when executed by one or more processors, cause one or more processors to perform the operations described herein.

[052] Still referring to FIGURE 3, the power supply may also include an indicator or indicators 352. In some cases, the indicator(s) 352 include a current indicator, pressure gauge, fault indicator and / or other operational control signals. Additionally or alternatively, the indicator(s) 352 may include a display that may show the identity of the currently identified components and / or display warnings when a user attempts to change the power settings to unsafe settings.

[053] As mentioned, FIGURE 4 illustrates a high-level flowchart of the operations performed by torch assembly 301 of Petition 870260075450, dated 07 / 29 / 2026, page 31 / 104 28 / 40 FIGURE 3 (which, again, may be representative of the torch assembly 20 of FIGURES 1A - C), configured according to an exemplary embodiment. Initially, in 410, one or more imaging devices (e.g., imaging devices 160) optically acquire one or more images and / or image data representative of one or more interchangeable torch components (e.g., consumable components) that are installed within / on the torch assembly 301 (i.e., consumable components included in a torch of the torch assembly 301). In some embodiments, one or more imaging devices constantly optically acquire one or more images and / or image data representative of the operating end of the torch body and any interchangeable torch components installed thereon.On the other hand, one or more imaging devices may only optically acquire one or more images and / or image data representative of the operating end of the torch body and any interchangeable torch components installed thereon at predetermined intervals. The predetermined intervals may be time-based (e.g., every 30 seconds) or action-based. Examples of action-based predetermined intervals include intervals that begin in response to: a power supply connection; a power supply cycle; a fire signal being received on a mechanized torch; an actuation of a trigger included in the torch; and / or a locking of interchangeable torch components in place on the torch body. In some embodiments, the light source included in the torch body may only illuminate the interchangeable torch components (and any included indicators) at the predetermined intervals.

[054] In some embodiments, the torch assembly transmits acquired images and / or image data to a source of Petition 870260075450, dated 07 / 29 / 2026, p. 32 / 104 29 / 40 power supply without analyzing acquired images and / or image data in 420. For example, the torch assembly can send acquired images and / or image data to the power supply as the images and / or image data are acquired and / or in batches or sets. On the other hand, in 430, a processor in the torch assembly (e.g., processor 190) can analyze the acquired images and / or image data with optical recognition techniques to identify one or more markings included on one or more interchangeable torch components. For example, if the imaging device is constantly acquiring images and / or image data, the processor can detect changes in the acquired images and / or image data and apply optical recognition techniques to the images and / or image data when a change is detected (e.g., compare one or more markings to an image library).Alternatively, if the imaging device is acquiring images and / or image data at predetermined intervals, the processor can analyze each acquired image and / or image data using optical recognition techniques.

[055] If the torch assembly applies optical recognition techniques to the acquired images and / or image data at 430, the torch assembly can determine, at 440, whether one or more markings in the acquired images and / or image data are recognized. If one or more markings are recognized at 440, the marking(s) or data representing the marking(s) are transmitted to the power supply at 450. However, in some embodiments, prior to transmission at 450, the torch assembly can determine whether the parts required for an operation are in place at 445 (this determination does not always need to occur, and thus 445 is shown in dashed lines). For example, if a Petition 870260075450, dated 07 / 29 / 2026, page 33 / 104 30 / 40 torch assembly in particular requires that an electrode, a gas distributor, a torch tip and a protective cover function properly for a specific plasma cutting operation; the torch assembly can determine that all these components are currently installed in the torch assembly before starting the operation.

[056] If the torch assembly (or more specifically, the torch assembly processor) determines that a required component is not installed (or is not installed correctly), the torch assembly determines that the parts are not in place at 445° and prevents the power supply from operating at 460° (i.e., sending a signal to the power supply that prevents the power supply from delivering power). For example, if a protective cap is installed on a torch before the torch tip is in place, the processor may determine that the parts are not in place at 445° and prevent plasma cutting operations at 460°.This determination can be made by counting a number of markings identified by one or more imaging devices and comparing the number to a predetermined number (e.g., four markings may be required to determine if parts are in place), identifying markings from each of any number of predetermined required categories (e.g., parts are in place when markings from an electrode category, a gas distributor category, a torch tip category, and a protective cup category are identified). Additionally, or alternatively, the parts being in place determination may depend on whether the markings are seen outside a certain focus range. For example, if the markings are not in focus in an acquired image, the associated part may be determined to be incorrectly installed, and thus the associated part may be. Petition 870260075450, dated 07 / 29 / 2026, page 34 / 104 31 / 40 considered as not being in place.

[057] If the torch does not perform a part analysis in place at 445, the marking(s) or representative data of the marking(s) will be transmitted to the power supply at 450. For example, if the ESAB 60A GOUGE markings are identified by an imaging device, the processor may, in some embodiments, simply transmit these markings to the power supply. Alternatively, the processor may determine operational settings based on the identification of one or more markings and transmit instructions related to the operational settings of the power supply. For example, upon recognizing the ESAB 60A GOUGE markings, the processor may instruct the power supply to provide 60 amperes and supply plasma gas at a pressure suitable for chiseling and set any other operational parameters necessary for chiseling at 60 amperes. The transmitted instructions may be considered representative data of the detected clues.However, this is not the only representative data of the detected clues. Other examples include digital data representative of the clues (e.g., valid and chiseling at 60A) and analog data representative of the clues (e.g., values ​​assigned to valid chiseling and 60A). As a more specific example, by determining that the clues in acquired images and / or image data correspond to markers stored in a library (e.g., image IDs 364), the torch assembly can transmit the image and / or image data and a valid determination to the power supply, which can handle the remaining operations associated with the automatic configuration of the torch assembly for the identified and valid components.

[058] Regardless of what exactly is transmitted in Petition 870260075450, dated 07 / 29 / 2026, page 35 / 104 32 / 40 450, if the signals are identified, the torch assembly can at least continue with the torch operation. If, on the other hand, at 440, the torch assembly processor does not recognize the signals at 410, the processor may prevent the torch assembly from operating at 460. That is, the torch assembly may be prevented from initiating a process related to cutting or welding.

[059] Still referring to FIGURE 4, although the embodiments discussed here have, for the most part, discussed torch assemblies with internal imaging devices, in some embodiments, the imaging device may actually be included in the power supply and the cabling between the torch assembly and the power supply may include optical components to optically connect the power supply to the operating end of the torch body. In these embodiments, the power supply may perform the operations represented in FIGURE 4. Alternatively, the torch assembly may collect information from the power supply (or from another external imaging device, such as an imaging device disposed on a torch cable extending between the torch and the power supply) that is acquiring images and / or image data from the operating end of the torch (and any components installed thereon).

[060] FIGURE 5 represents a high-level flowchart of the power supply operations configured according to an exemplary embodiment. Initially, in 510 or 515, the power supply receives data from the torch assembly. More specifically, in 510, the power supply receives one or more images and / or image data from one or more interchangeable torch components included in a torch, or representative data of the acquired images and / or image data. As mentioned above, the representative data of the acquired images Petition 870260075450, dated 07 / 29 / 2026, page 36 / 104 33 / 40 and / or image data may include digital data representing the markings (e.g., valid and chiseling 60A), analog data representing the markings, and instructions for adjusting the operating parameters. If the data are or include instructions, the power supply can simply adjust the operating parameters supplied to the torch assembly at 530 (and thus 520 is shown in dashed lines). However, if the data do not include instructions or identify the interchangeable torch components (this data is received at 515), the power supply must determine the identity of one or more interchangeable torch components from clues in the acquired images and / or image data. For example, if the power supply receives the images and / or image data, the processor in the power supply can apply optical recognition techniques to the images and / or image data.As another example, if the power supply receives analog or digital data representing clues identified in acquired images and / or image data, the power supply can consult a lookup table with this data to identify one or more interchangeable torch components associated with the clues represented by the received data. In particular, in embodiments that identify combinations of interchangeable torch components in the power supply, one or more imaging devices can send data to the power supply so that, in 510 (or 515), the power supply can receive data from multiple sources.

[061] If in 515 or 520 the power supply does not receive an identity or is unable to determine an identity, respectively, the power supply may determine that an interchangeable torch component is incompatible with the particular torch assembly, whether it is a cutting torch assembly or Petition 870260075450, dated 07 / 29 / 2026, p. 37 / 104 34 / 40 plasma, a welding torch assembly, or any other torch assembly (the plasma components mentioned here are only examples, and the techniques presented here can identify any components for any type of torch assembly). For example, if the data received at 510 indicates that the component does not include evidence, the power supply can determine that the interchangeable torch component is incompatible with the torch assembly.

[062] In some embodiments, the power supply may also determine whether the parts are in place at 525 (however, in some embodiments, the power supply does not determine whether the parts are in place and therefore 525 is shown in dashed lines). The power supply makes this determination, according to the description of step 445 included in the list above which, for brevity, will not be repeated here. That is, in some embodiments, the power supply determines whether the parts are in place and thus the description of 445 included above may be applicable to step 525. In some of these embodiments, the power supply determines whether the parts are in place instead of the torch assembly making this determination. Alternatively, the power supply and the torch assembly may work together to determine whether the parts are in place.That is, the power supply and the torch assembly can complete the operations described above in connection with step 445 together or in unison. In other embodiments, the torch assembly can independently process a determination of parts in place (and the power supply can ignore this step). If the power supply analyzes the indications to determine if the parts are in place, the power supply can refrain from initiating a welding or cutting process, in 527, when the parts are not in place. When the parts... Petition 870260075450, dated 07 / 29 / 2026, page 38 / 104 35 / 40 are in place, the power supply can proceed to step 530.

[063] In step 530, the power supply adjusts the operating parameters of the torch assembly based on the identity determined in 520. For example, if an interchangeable torch component is identified as a 60 Ampere or 40 Ampere cutting tip for a plasma cutting torch assembly, the power supply may adjust the power delivery so that 60 Amps or 40 Amps of current are delivered to the torch assembly, respectively. Furthermore, if the power supply detects that a user is attempting to change the current to 100 Amperes when the power supply determines that the 60 Ampere or 40 Ampere torch tip is installed in the torch body, the power supply may automatically roll the current back to a safe level (i.e., to 60 or 40 Amps).That is, in some cases, the techniques may not prevent the arc from starting, but will ensure that the arc transfer is carried out with optimal operating parameters (to ensure safety and high-quality operations). Alternatively, if the torch tip is identified as a chiseling tip, the power supply can be adjusted to a chiseling mode. Furthermore, if the torch tip is not identified, the power supply can prevent arc transfer to a workpiece or limit operating settings to very low levels to ensure that the unidentified component does not fail and damage other torch components or endanger the end user. This can prevent counterfeit or unsuitable / undesirable components from being used or damaging the torch body.

[064] Now, returning to FIGURE 6, this figure represents another high-level flowchart of the power supply operations. Petition 870260075450, dated 07 / 29 / 2026, page 39 / 104 36 / 40 configured according to another exemplary embodiment. In FIGURE 6, the power supply initially receives acquired images and / or image data of an interchangeable torch component or a combination of interchangeable torch components from the torch assembly in 610. In 620, the power supply determines whether one or more interchangeable torch components included in the acquired images and / or image data contain any identifiable evidence. This determination can determine whether the parts are genuine (i.e., suitable for the torch assembly and not counterfeit). In some embodiments, the image library used to identify the evidence may include labels indicating whether the evidence is genuine. Alternatively, the image library may only include genuine evidence so that only genuine evidence is identified.

[065] If identifiable evidence is found in 620 (and thus the parts are determined to be genuine in 620), the power supply can then determine identities for any identifiable interchangeable torch components currently installed in the torch assembly in 630. In step 640, the power supply determines whether the identified interchangeable torch components are consistent or compatible for a specific cutting / welding operation. To make this determination, the power supply can determine whether several identified interchangeable torch components can or should be used together and / or whether one or more identified interchangeable torch components are suitable for the selected welding / cutting operations.For example, the power supply can determine whether an electrode, a torch tip, a gas distributor, and a protective cover currently installed on a torch assembly are all suitable for a 100 Amp air / air cutting operation. Petition 870260075450, dated 07 / 29 / 2026, page 40 / 104 37 / 40

[066] If, instead, at 620 the power supply determines that one or more parts are not genuine and / or unsuitable for the particular torch assembly (i.e., one or more parts are counterfeit), the power supply may enter a fault mode at 625. Similarly, if at 640 the power supply determines that at least one of the identified interchangeable torch components is incompatible with other identified interchangeable torch components (i.e., an interchangeable torch component is not suitable for 100 Ampere / air cutting) the power supply may enter a fault mode at 645. When the power supply is operating in fault mode, it may prevent the torch assembly from operating.Alternatively, in fail-safe mode, the power supply can limit torch operations to operations that do not exhibit quality degradation and / or become unsafe when operating with the identified interchangeable torch components. By comparison, if the power supply determines that the identified interchangeable torch components are compatible with each other and / or suitable for a specific cutting / welding operation, the power supply can automatically adjust, at 650, process parameters (i.e., operational parameters) to be delivered to the torch assembly based on the identity of the component or components. That is, the power supply (or the torch assembly) can determine that all identified components are intended for use in a specific operation and the power supply can adjust the operational parameters of the torch assembly to support that particular operation.

[067] Among other advantages, the techniques described and shown here allow the user to make a quick and seamless transition between various cutting and welding operations. The techniques here Petition 870260075450, dated 07 / 29 / 2026, page 41 / 104 The techniques presented here also provide greater safety and improved operating conditions for welding and cutting operations by automatically configuring operating parameters (e.g., energy and gas transfer parameters) for the specific components currently installed / included in a torch assembly. Consequently, both inexperienced and experienced users do not need to know (or even try to find) the specific settings for each component, nor do they need to identify the components when installing them. In other words, the techniques presented here eliminate the need for the end user to have knowledge of ideal settings and / or counterfeit parts. Furthermore, even if a user attempts to use an unsafe or suboptimal setting, the techniques presented in this document can prevent the user from doing so (since the techniques presented here ensure that ideal settings are applied for specific operations with genuine parts).This will result in improved and more consistent performance, greater ease of use, and increased security.

[068] As with other examples, the techniques presented here can identify components economically and reliably. That is, at least compared to adding electrical components to a torch component, adding a marking to a component can be considerably cheaper and at least as reliable.
