The role of the molten gas shielded welding torch is to conduct welding current, to guide the welding wire and to protect the gas. According to their use can be divided into semi-automatic welding torch (hand-held) and automatic welding torch (installed on the mechanical device) two. The inside of the torch is equipped with a different aperture of the conductive nozzle to meet the needs of different diameter wire. The torch also has a channel and nozzle for conveying the protective gas to the weld zone. The nozzle is a consumable part and should be easily replaced. When the welding current through the contactor and other components generated when the resistance heat and arc radiant heat together will make the welding torch fever, so use a certain measure to take the cooling torch, cooling methods are air cooling and water cooling two. For air-cooled torch, the welding current can be up to 600A under CO2 gas shielded intermittent load conditions. However, when using argon or helium protection, the welding current is usually limited to 200A. Semi-automatic welding gun with gooseneck and pistol type two. Gooseneck welding torch is suitable for small diameter wire, flexible and convenient, especially suitable for compact parts, difficult to reach the corner and some restricted areas of welding. Pistol-type welding torch is suitable for thicker diameter wire, the internal use of circulating water cooling. The basic structure of the automatic welding torch is the same as that of the semi-automatic welding torch, but its current carrying capacity is large (up to 1500A), the working time is longer, and the internal circulating water is cooled and installed directly in the lower part of the welding head.
