<P>PROBLEM TO BE SOLVED: To provide a TIG welding torch 31 which can adjust easily a protruding length from an end 28a of a nozzle of an electrode 25. <P>SOLUTION: In the TIG welding torch 31, an electrode clamping cap 32 is thrusted into a base end part 23b of a torch body, and thereby an end 24a of a collet is pressed against the inside face of an end 26a of a collet body. A through-hole 32d in which an electrode 25 is inserted is formed at an electrode clamping cap 32. An electrode insertion hole 33d in which a base end part 25b of an electrode is intercalated from the end of a cap 33 for electrode projection length adjustment is formed, and a bottom 33e of this electrode insertion hole contacts a base end part 25b of the electrode which has projected from a base end part 32b of the electrode clamping cap. <P>COPYRIGHT: (C)2012,JPO&INPIT |
