The present invention relates to a torch for a TIG welding machine and, more specifically, to a torch for a TIG welding machine capable of easily supplying argon gas by having a means for preventing the deformation of a collet holding a tungsten electrode and capable solving a problem of discarding the collet. The present invention has a pressure spring pressuring the collet between the collet and a back cap coupled to the rear side of a torch body to prevent the collet holding a tungsten electrode from being deformed due to heat or has the pressure spring inserted into a spring groove formed in the back cap. Also, the torch for a TIG welding machine can prevent the collet holing a tungsten electrode from being deformed due to heat by elastically supporting the collet using an elastic means installed in a coupling groove formed in the back cap. |
