[0002] A welding gun is a tool used in welding processes such as arc welding and gas shielded welding. It is usually composed of components such as a handle, a cable, an electrode holder and a trigger. The welding gun is a tool that connects or fills metal materials by transmitting current and controlling the welding arc.

[0003] When an existing welding gun is used in conjunction with a robotic arm, the circuit of the welding gun is often scratched and squeezed due to the movement and adjustment of the robotic arm. If the circuit of the welding gun is not stored, limited and protected, the circuit of the welding gun will be damaged, thereby affecting the service life of the welding gun.
