A welding gun refers to the part that performs the welding operation during the welding process. It is a tool used for gas welding. It is shaped like a gun, has a nozzle at the front end, and sprays out a high-temperature flame as a heat source. It is flexible to use, convenient and fast, and the process is simple. The welding gun is one of the main equipment for hot air welding, and is composed of a heating element, a nozzle, etc. According to its structure, there are gas welding guns, electric welding guns, fast welding guns, and automatic welding guns.

[0003] The welding gun is used to clamp the stud, lift the stud (ignite the arc), press the stud down, and transmit the welding current. The welding gun also has a support frame to ensure that the stud is perpendicular to the workpiece surface.
