WELDING TORCH AND MOUNTING JIG THEREOF

摘要

The present invention relates to a welding torch including a mounting jig for mounting a wire-aiming guide which feeds a welding wire toward a molten pool of a work piece, wherein the mounting jig has a male screw that can be screwed into a female screw provided in a torch body, and is detachably mounted to the torch body; and a mounting jig. The present invention provides the welding torch with which a wire-aiming guide can be stably mounted and which can mount a highly versatile wire-aiming guide; and the mounting jig.

主权项

1. A welding torch comprising:
a non-consumable electrode which generates an arc between a work piece and the non-consumable electrode; a collet which supports the non-consumable electrode in a state where the non-consumable electrode is inserted; a collet body on the inside of which the collet is held in a state of projecting the non-consumable electrode from a front end of the collet body; a torch body on which the collet body is mounted, and which comprises an electric supplying part for supplying electric power to the non-consumable electrode through the collet body and the collet and a passage for supplying a shield gas; a torch nozzle which is mounted on the collet body in a state of surrounding the non-consumable electrode and emits the shield gas toward a molten pool of the work piece which is generated by the arc; a torch cap which has a male screw which can be screwed into a female screw of the torch body which is formed on the side opposite to the side where the collet body is mounted and is detachably mounted on the torch body; a wire-aiming guide which feeds a welding wire toward the molten pool of the work piece; and a mounting jig with which the wire-aiming guide is mounted; wherein the mounting jig comprises a male screw which can be screwed into the female screw of the torch body, and is detachably mounted on the torch body.
