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 13):
The TIG welding device in accordance with  claim 12 , wherein\n the driving unit includes a servo mechanism with a servo motor, and when lifting the torch electrode upward in the touch start system from a state where the torch electrode contacts the welding workpiece, the servo mechanism moves up the torch body fixedly held by the electromagnetic solenoid at the linear movable part by an intended distance.
