<P>PROBLEM TO BE SOLVED: To provide a grounding tool for a welding machine with which the area to be restored by applying a coating film after repairing work is reduced by shortening the installation time for grounding and restricting peeling of a coating film of a place for grounding to only a limited portion near a place where a washer is weld-planted. <P>SOLUTION: A cord connecting part 22A is formed at a rear end of a grounding body 20A formed by an electric conductor for connecting a cord for an electrode. At a tip end of the grounding body, an insertion port 2A is formed for inserting a flat ring-shaped washer 8 that is weld-planted on a balancing plane of a sheet metal, and a hooking part 3A is formed for hooking the washer in the insertion port. Further, at a front face part of the tip end of the grounding body, an energization guiding part is formed for introducing energization by abutting on a sheet metal face in a state of the hooking part hooking in a through hole 9 of the washer. Grounding is performed by the washer weld-planted on the sheet material face and the energization guiding part. <P>COPYRIGHT: (C)2012,JPO&INPIT |
