PROBLEM TO BE SOLVED: To provide a welding torch which has simplified attachable/detachable structure, thereby enabling a torch body to be replaced by a simple operation.SOLUTION: The welding torch has a connector member 5 and a connector case 7 to be connected to an inner pipe of a pipe for a torch at the root part of the welding torch, and a corn-shaped fitting hole 5a is formed in a fore end of the connector member 5. The torch body 2A includes a tip body 20 having a corn-shaped fitting part 29 on a terminating end thereof. The torch body 2 slides a lock member 9 while the corn-shaped fitting part 29 at the terminating end is fitted in the corn-shaped fitting hole 5a of the connector member 5, and a small diameter hole 9c of a lock opening part 9a is fitted in a lock groove 28 of the tip body 20 to lock the fitting state of the corn-shaped fitting part 29 and the corn-shaped fitting hole 5a. When the lock member 9 slides in the opposite direction to the above, the locked state is unlocked, and the torch body 2 is detached from the connector member 5. |
