Abstract:
Through the present invention, the load of a torch ( 16 ) applied to a welding workpiece (W) in a touch start method is reduced, and stability is significantly enhanced. A welding head ( 10 ) has a rigid straight-advancing movable part ( 12 ), an elevator drive tower ( 14 ) for moving the straight-advancing movable part ( 12 ) straight forward in the vertical direction, and a torch ( 16 ) mounted on the straight-advancing movable part ( 12 ) so as to be able to move in the vertical direction. One end part of a balance arm ( 28 ) rotatably attached to a multi-purpose support part ( 22 ) of the straight-advancing movable part ( 12 ) is connected to a torch body ( 30 ), and a balance weight ( 98 ) is attached to the other end part of the balance arm ( 28 ).

Claim (Index 10):
The TIG welding device in accordance with  claim 8 , wherein the second electrode holder includes a taper part fitted in the torch body integrally with the torch electrode through the collet and capable of coming into pressing contact with an upper end portion of the slit part which is closer to the upper end of the collet.
