A tig welding torch is provided to preclude argon gas with large pressure from being suddenly ejected from a torch head, and to generate the initial arc stably by placing a sintering metallic filter on a filter mounting part and passing the argon gas through the sintering metallic filter slowly. A head part(11) and a body part(13) are integrally formed. An argon gas path(15) is formed to the body part. A coupling part is formed to the body part. A mounting part(17) is formed to the body part. A sintering metallic filter(21) is placed on the mounting part. The mounting part is formed to one end of the connector. One end of an argon gas supply pipe inserted in the body part is fitted to one end of the connector. One periphery of the connector is welded with the argon gas supply pipe.
