In addition, the welding torch may be classified into large, medium and small types according to the length of the torch. In order to perform various welding operations, the operator must purchase and use various welding torches according to the welding method, .

On the other hand, Korean Patent No. 10-1412374 entitled " Welding torch and its assembling method " discloses a technique for easily assembling and disassembling a contact tip, which frequently occurs during welding, without a separate tool.

Korean Patent Laid-Open Publication No. 10-2014-0078826 " Welding Torch " discloses a welding torch capable of easily separating a welding tip from a tip holder.

In other words, in the conventional technologies, the welding part is changed only according to the welding method, and the welding part is changed only by the welding method. I can not do it.

That is, the electrode collet taper part 554 interferes with the electrode collet chuck taper part 532 on the inner side of the weld 560 so that the electrode collet chuck 530 presses the tungsten electrode 510 . When the electrode collet chuck 530 is pushed forward by a predetermined distance during the pressing operation of the electrode adjustment bar button 574, interference between the electrode collet taper part 554 and the electrode collet chuck taper part 532 is canceled. So that the tungsten electrode 510 can be drawn out to a predetermined length.

As a result, in the present embodiment, when the tungsten electrode 510 is constrained by the tapered portions 532 and 554 of the electrode collet chuck 530 and the electrode collet 550, 574 are pressed, the electrode collet chuck 530 is pulled out to the front side and the interference is canceled, so that the binding force applied to the tungsten electrode 510 is canceled.

Accordingly, the tungsten electrode 510 can be drawn out by a predetermined length due to its self-weight as the electrode collet chuck 530 is released, and is returned to its initial position when the electrode adjusting bar button 574 is depressed The clamping force is exerted by the electrode collet chuck 530 to maintain the fixed position.
