[0002] The welding gun refers to the part that performs the welding operation during the welding or cutting process. It is flexible to use, convenient and fast, and the process is simple;

[0003] The welding gun uses the high current and high voltage of the welding machine to generate heat that is gathered at the terminal of the welding gun to melt the welding wire. The molten welding wire penetrates into the part to be welded. After cooling, the objects to be welded are firmly connected into one.

[0004] The power of the welding gun depends on the power of the welding machine and the welding material;

[0005] The gun wire used for plasma cutting gun or argon arc welding gun is generally assembled by cloth cover, control line, hose, and copper wire in the hose. It has the following disadvantages: 1. The hose is easy to break; 2. The cloth cover is flammable when encountering sparks generated during work, and it is easy to get caught on iron or angular places when moving; 3.
