Summary:PROBLEM TO BE SOLVED: To provide a TIG welding which has a large rotation stroke, is suitable for the welding of a narrow part, is small-sized, enables simplification of teaching and reduction in the operation quantity of a robot, and adds a filler wire at an angle suitable for welding. SOLUTION: In the TIG welding torch in which a non-consumable electrode 7 is arranged inside a torch main body 3a and whose torch main body 3a is rotated around the non-consumable electrode 7, the torch is characterized in that a wire feed pipe 9a is provided in the torch main body 3a, the torch main body 3a is rotatably supported by a rotation support part (housing 10), and the filler wire 25 is fed to the wire feed pipe 9a from the more opposite side to a weld zone than the rotation support part (housing 10) of the torch main body 3a.
