Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way constitutes a limitation on the present application and its application or use. Embodiment

[0024] A torch with double water-cooled cables, as Figures 1 to 3 shown, includes a torch body 1, a handle assembly 2 and a cable assembly 3. The torch body 1, the handle assembly 2 and the cable assembly 3 are connected in sequence. The cable assembly 3 includes a gas pipe assembly 301, a first water-cooled cable assembly 302 and a second water-cooled cable assembly 303. The gas pipe assembly 301, the first water-cooled cable assembly 302 and the second water-cooled cable assembly 303 pass through the handle assembly 2 and are connected to the torch body 1. An electric arc is generated by inputting current into the torch body 1 to achieve high-temperature welding. A cooling cavity is provided inside the torch body 1. The water inlet pipes in the first water-cooled cable assembly 302 and the second water-cooled cable assembly 303 pass through the cooling cavity. The handle assembly 2 is the main part for grasping and holding. The gas pipe assembly 301 is used to input a protective gas into the torch body 1, which flows out during welding to play a protective role. The first water-cooled cable assembly 302 passes through cooling water, and the cooling water flows into the torch body 1 for circulation. The cooling water enters the second water-cooled cable assembly 303 from the inside of the torch body 1. During the welding process, the first water-cooled cable assembly 302 and the second water-cooled cable assembly 303 can transmit the high current of the welding machine to the torch body. At the same time, in the water circuit circulation, the water can cool the water-cooled cable assembly 3 and the torch body to ensure that they are not burned during the welding process, solving the problems that the existing cables are prone to breakage and the operation convenience of thickened cables is poor.

[0025] The first water-cooled cable assembly 302 and the first water-cooled cable assembly 302 include a conductive cable 30201 and a cable protection sleeve 30202. The cable protection sleeve 30202 wraps the conductive cable 30201, and the cable protection sleeve 30202 protects the conductive cable 30201, reducing the possibility of cable damage.

[0026] The torch body 1 includes a rubber body 104, which is wrapped with a body insert 103. The body insert 103 is threaded and electrically connected to an electrode collet 102. A nozzle 101 is threaded onto the body insert 103. The other end of the rubber body 104 is fixedly connected to an electrode 105. An opening collet 106 is connected to the electrode 105, and an electrode cap 107 is threaded onto the opening collet 106. An electric arc is generated by energizing the electrode 105 for high-temperature welding. The nozzle 101 is installed on the body insert 103 by threading and can guide and protect the gas to achieve welding.

[0027] The cable assembly 3 further includes a switch cable 304. The switch cable 304 is connected to a power supply, and the other end of the switch cable 304 is connected to the torch body 1 to energize the torch body 1 through the switch cable 304. Embodiment

[0028] Based on Embodiment 1, an implementation manner of a torch with a double water-cooled cable is provided:

[0030] The gas pipe assembly 301 and the torch body 1 are locked tightly by a clamp. The water inlet joint 10301 of the first water-cooled cable assembly 302 is electrically connected by threading, and the second water-cooled cable assembly 303 is connected to the water return joint 10302.

[0031] The first water-cooled cable assembly 302 and the second water-cooled cable assembly 303 are internally hollow, and the hollow is a water pipeline.

[0032] The first water-cooled cable assembly 302 and the second water-cooled cable assembly 303 are respectively provided with a water inlet 4 and a water outlet 5.

[0033] Different from Embodiment 1, water enters from the water inlet 4 of the first water-cooled cable assembly 302, circulates in the torch body, and is discharged from the water outlet 5 of the second water-cooled cable assembly 303. The water-cooled cable assembly 3 and the torch body jointly form a cooling circulation loop, realizing the internal circulation of cooling water, and the water can cool the water-cooled cable assembly 3 and the torch body.

[0034] In the description of the present application, it should be understood that the orientation or positional relationship indicated by terms such as "center", "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only used to explain the relative positional relationship and movement conditions between components in a specific posture. If the specific posture changes, the directional indication will also change accordingly. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0035] In the description of the present application, it should be noted that unless otherwise clearly specified and defined, the terms "mounted", "connected" and "coupled" should be construed broadly. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood through specific circumstances.

[0036] The above are only the preferred embodiments of the present application. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present application, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present application.
