MIG welding gun is divided into ten parts: 1. Contact nozzle 2. Gas protection nozzle 3. Insulator cylinder 4. Connecting rod 5. Ceramic sifier 6. Welding gun neck 7. Welding coaxial cable 8. Conduct pipe 9., tracheal pipe 10. Water pipe: Water-cooled welding gun should be used when the above current is exceeded. Of the semi-automatic welding guns, goose-necked is the most widely used. Suitable for fine wire, flexible and convenient, can be welded in any position. Pistol torches are suitable for coarser wires because of the large current and the frequent use of water-cooled. The basic structure of automatic welding gun is the same as that of semi-automatic welding gun, but the current is large and the working time is long. Usually, water is used for cooling.
