Claims

[Scope of utility model registration request]

A collet with a hole in the shaft center for inserting a non-consumable electrode and an axial slit in one end, a torch body with a wedge-shaped inner surface that comes into contact with one end of the collet, and a torch body that is screwed into the torch body. It consists of a cap with a surface that comes into contact with the other end surface of the collet, and by screwing the cap onto the torch body, compressive force is applied to the collet.
A welding torch having an electrode held by a wedge action, characterized in that it is provided with a biasing device that generates a predetermined amount of force between the other end surface of the collet and the opposing surface of the cap. torch.
