PROBLEM TO BE SOLVED: To provide a TIG welding torch which enables cladding by welding in a small diameter hole is. SOLUTION: An upper end of a torch head 2 is fixed to a tip part of an arm. When it is fixed, adjustment is made so that the axis of the torch head 2 and an extension direction of the arm may have an angle of 120-150 degree. And, an inert gas storage chamber 4 is provided in the torch head, and to the storage chamber, a gas feeding cylinder 9 extending to the axial direction of the torch head 2 is connected. Plural gas blowing ports 9a, 9b are formed in the gas feeding cylinder. Thereby, by setting fixing position and the angle of the torch head, downsizing of the torch can be made. A stable shielding by the inert gas can be made with the storage chamber and feeding cylinder, and the downsizing of the torch can be made without impairing weldability.
