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 8):
The TIG welding device in accordance with  claim 1 , comprising:\n a cylindrical collet having slit parts provided at opposite end portions thereof and being housed in the torch body in a removable fashion while the torch electrode penetrates the collet; a first electrode holder for holding the torch electrode on an axis of the torch body at a lower end portion of the torch body through the slit part which is closer to a lower end of the collet; and a second electrode holder for holding the torch electrode on the axis of the torch body at an intermediate portion of the torch body through the slit part which is closer to an upper end of the collet.
