[0002] At present, the existing water-cooled welding gun adopts a copper gun barrel, and the strength of the welding gun itself is relatively poor. The conductive nozzle seat and the gun barrel are connected by a pipe thread, and the conductive effect is poor. In addition, the total amount of cooling water stored in the gun barrel is small, and the conductive nozzle enters the cooling chamber for a short time, and the cooling effect is average. The conductive nozzle seat is very easy to adhere to welding slag and spatter during the welding process, and it is very difficult for workers to clean it. The cleaning frequency is high. The threaded connection strength between the conductive nozzle seat and the gun barrel is low. If there is a lot of welding slag and spatter, the thread between the conductive nozzle seat and the gun barrel is very likely to break during the cleaning process, resulting in wire breakage. Therefore, it is very necessary to invent an automatic cleaning water-cooled welding gun for flux-cored welding wire.
