Gas welding torch is generally divided into automatic welding gun, semi-automatic welding gun. Semi-automatic welding guns need hand-held operation, also known as hand-held torch, should be designed to minimize weight and ease of operation. Semi-automatic welding guns usually have two forms: gooseneck and pistol type.
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 larger diameter wire, which requires a higher cooling effect, so often use the internal circulating water cooling. Semi-automatic welding torch can be installed with the wire feeder, can also be separated.
