BRIEF DESCRIPTION OF THE DRAWINGS

[0006] These and / or other aspects will become apparent and more readily understood from the following description of some example embodiments taken in conjunction with the accompanying drawings.

[0010] The drawings are not necessarily drawn to scale. Where appropriate, similar or identical reference numbers are used to represent similar or identical components. DETAILED DESCRIPTION

[0011] Various embodiments of the present disclosure allow the user to easily set applicable welding parameters by pressing a button on the user interface to switch between stock parameters and custom parameters. Thus, this can save the user from having to access each parameter and traverse the parameter range on the screen while allowing the user to know that the default values ​​are acceptable for the most common applications.

[0012] When a feature is activated by pressing a button, an indicator such as a light will illuminate as a means of quickly identifying that the feature is activated. Continuing to hold the button for a period of time will perform a factory reset of the entire unit.

[0013] Thus, embodiments enable a welder to set parameters other than the amperage ("heat") setting simply by pressing a button.

[0014] Various advantages of the embodiments of the present disclosure may be, for example: reducing the training and setup time associated with selecting acceptable parameters; reducing product rework associated with the use of improper parameters; eliminating or reducing troubleshooting time by quickly allowing all applicable parameters to be set to certain custom values ​​with the push of a button; eliminating or reducing troubleshooting time by providing a factory reset function on the front-end user interface; allowing the user to switch between factory settings and custom settings for comparison / training purposes; allowing the user the flexibility to set the maximum amperage independently of other parameters to achieve the user's desired output control calibration / response rate; a supervisor can quickly check whether the welder is using the factory parameters by simply glancing at the indicator (e.g., light or LED) on the button; and the like.

[0015] Figure 1A is a high-level block diagram of an example welding-type power supply according to an embodiment of the present disclosure. Figure 1A , a welding power source 100 is shown, which includes a power conversion circuit 110, a user interface 120, and a control circuit 130. A welding torch 140 that can receive welding power from the power conversion circuit 110 in the welding power source 100 via a cable 111 is also shown.

[0016] The power conversion circuit 110 receives input power from a power source that can provide, for example, 120VAC, 240VAC, 480VAC, etc., and outputs welding-type power. The user interface 120 provides various input and output devices for inputting / controlling the use of the welding-type power source 100, and various output devices for displaying the status and / or information about the welding-type power source 100.

[0017] The control circuit 130 includes a hardware device capable of executing instructions to perform specific functions. Thus, the control circuit 130 includes any one of a number of different types of processors, memories, logic circuits, etc. for controlling the welding-type power supply 100.

[0018] Figure 1B is a diagram of an example user interface according to an embodiment of the present disclosure. Figure 1B , showing Figure 1A1. The user interface (UI) 120 has a display 121. Although these displays are illustrated as two separate displays, various embodiments of the present disclosure may have a single display or more than two displays.

[0019] For example, UI120 may also display four selections of welding types 122-125. The welding type may be selected by, for example, a selector 126. To select a welding type, the selector 126 may be turned until the arrow points to a particular welding type. Each welding type 122-125 may also have a corresponding light 122L-125L that may be turned on when the corresponding welding type is selected. There is also an encoder 127 that may be used to increase or decrease menu item values, such as welding current, etc. There are also input 1 devices 128 and input 2 devices 129 and their corresponding lights 128L and 129L. The input devices may be, for example, buttons, toggle switches, membrane buttons, etc.

[0020] Input 1 device 128 can be, for example, a menu button, which, when pressed, displays various levels of menus. For example, a short press can display a first menu, a longer press can display a second menu, etc. Once the desired menu is displayed, a shorter press than a short press of the first menu can allow advancement to the next menu item. If the value of the menu item can be adjusted, encoder 127 can be used to adjust the value of the displayed menu item. The menu name can be displayed on one or both of the displays 121 for a period of time. Thereafter, the first menu item can be displayed with its value. Therefore, the user can select a different value for the menu item, or move to the next menu item.

[0021] After accessing a menu, the menu mode may be exited by reaching a timeout by not touching the input 1 device 128 or encoder 127 for a default amount of time. The menu mode may also be exited by, for example, pressing the input 1 device 128 for a period longer than a maximum period of time to access the most recently accessed menu. When exiting the menu, the currently set welding current may be displayed on the displays 121. For example, one display 121 may display the words "welding current" while another display 121 may display the welding current in amperes.

[0022] For example, when a menu is accessed, the light 128L associated with the input 1 device 128 may turn on, and when the menu mode is exited, the light 128L associated with the input 1 device 128 may turn off.

[0023] The input 2 device 129 may be, for example, a pre-configuration state button. When the welding-type power supply 100 enters the pre-configuration state, a light 129L associated with the input 2 device 129 may turn on, and when exiting the pre-configuration state, the light 129L associated with the input 2 device 129 may turn off. When the welding-type power supply 100 is not in the pre-configuration state, the pre-configuration state may be entered by pressing the input 2 device 129, and when the welding-type power supply 100 is in the pre-configuration state, the pre-configuration state may be exited by pressing the input 2 device 129.

[0024] When entering the pre-configuration state, a control circuit, such as the control circuit 130 in FIG. 1 , can load a predetermined set of welding parameters for controlling, for example, the power conversion circuit 110. The welding current can be displayed in the display 121. When power is first applied, the control circuit 130 can set the welding current to a default value. If necessary, the user can then adjust the welding current to a desired value using, for example, the encoder 127. While the welding current can be adjusted, all other parameters selected as part of the pre-configuration state can be unchanged. Thus, the pre-configuration state can provide welding parameters useful for a particular welding type selected from the welding types 122-125.

[0025] Once the welding current is changed (this change is persistent between power cycles), the value is stored in the welding power supply 100. Therefore, the welding current can be used in the future until the welding current is changed. Various embodiments of the present disclosure can provide a warning when attempting to change any other parameter while in a pre-configured state. For example, the input 1 device 128 can be used to access menus and menu items. However, attempting to change a menu item value using the encoder 127 may cause, for example, the display 121 to flash to indicate an error message. The error message may flash for a period of time, or continue to be displayed for a period of time. Various embodiments may, for example, cause all associated lights on the UI 120 to flash. Therefore, it can be seen that various things can be done to indicate an error state.

[0026] Although the various lights 122L-125L and 128L-129L are generally described as lights, various embodiments of the present disclosure may use LEDs or any other light emitting device. In addition, in addition to being displayed via the various lights 122L-125L and 128L-129L, or in lieu of one or more of the various lights 122L-125L and 128L-129L, the selected welding type, the accessed menu mode and / or the entered pre-configured state may all be displayed, for example, in the display 121.

[0027] The input 1 device 128 may also be used to perform a factory reset of the welding-type power source 100. For example, when the input 1 device 128 is pressed for a certain amount of time, a message may be displayed on the display 121 indicating that a factory reset will occur. Keeping the input 1 device 128 pressed for a longer period of time will result in a factory reset. For example, there may be a countdown indicating how long the input 1 device 128 needs to be pressed to achieve a factory reset. Releasing the input 1 device 128 at any time before the countdown ends will result in the factory reset not occurring.

[0028] As described above, the display 121 may display the selected welding current value. However, when a welding operation occurs, that is, when the power conversion circuit 110 supplies welding current to the welding torch 140, the actual welding current and the actual welding voltage may be displayed on the display 121. Therefore, when the welding operation stops or pauses, that is, when no welding current is supplied to the welding torch 140, the selected welding current value is displayed on the display 121 again.

[0029] Figure 2 FIG. 1 is a block diagram of an example control circuit according to an embodiment of the present disclosure. Figure 2 , which may be used with various embodiments of the present disclosure and may be similar to Figure 1A The control circuit 200 is an example of the control circuit 130 in FIG.

The operating system 222 and the application 224 may be stored in, for example, the non-volatile memory 226 and may be copied to the volatile memory 228 for execution by the processor 210. Various aspects of the present disclosure may use different memory architectures depending on the design and / or implementation. For example, some aspects of the present disclosure may enable the operating system 222 and the application 224 in the non-volatile memory 226 to be executed at least partially from the non-volatile memory 226.

[0031] The communication interface 230 can allow the control circuit 200 to communicate with other devices via, for example, a wired protocol such as USB, Ethernet, FireWire, etc., or a wireless protocol such as Bluetooth, near field communication (NFC), Wi-Fi, etc. The wired or wireless protocol can also be, for example, a dedicated protocol. For simplicity, various types of radios used for communication can be referred to as transceivers. The communication can be, for example, communication with various sensors and / or devices capable of relaying sensor data. The communication interface 230 can also be used to communicate with other networks such as local networks, cellular networks, etc.

[0032] The control circuit 200 may also include an IO module 240 for communicating with a user via an input device 242 and outputting information for display on an output device 244. The input device 242 may include, for example, a switch, a slide switch, a membrane switch, a button, a touch-sensitive screen that may be part of a display, a microphone, etc. The touch-sensitive screen may have soft buttons, switches, slide switches, etc. that simulate their physical counterparts. The input device 242 may also include, for example, various sensors, cameras, etc. The output device 244 may include, for example, a display, a speaker, an LED, a vibration motor, etc.

[0033] In different embodiments, the processor 210 may operate using different architectures. For example, the processor 210 may use the memory 220 to store instructions to be executed, or the processor 210 itself may have a memory (not shown) for storing its instructions.

[0034] Various embodiments may use other architectures, where different functions may be grouped differently. For example, the grouping may be implemented in different integrated circuit chips. Alternatively, the grouping may combine different devices such as IO module 240 and communication interface 230. In addition, control circuit 200 may logically refer to various physical devices. For example, one or more output devices 244 may be located at a different location than one or more input devices 242.

[0035] The UI 120 and the control circuit 130 of FIG. 1 may be similar to Figure 2 Therefore, the IO module 240 may be similar to the UI 120, and the rest of the control circuit 200 may be similar to the control circuit 130 of FIG. 1.
