PROBLEM TO BE SOLVED: To significantly improve chamfering working efficiency by supporting a wire from below with a support mechanism arranged with plural recessed parts to support a wire on its upper face and pressing the wire from above up to the finish of arc spot welding with a pressing device actuating up/down at the time of arc spot welding to the both end faces of metal wire. SOLUTION: A support mechanism 9 arranged with a recessed part 10 supports a wire (a). The recessed parts 10 are formed in plural at a prescribed interval. A feed arm mechanism 11 having recessed parts 10a same as the recessed parts 10 is mounted to the side of the support mechanism 9. When the wire (a) is inserted into three recessed parts 10 of the support mechanism 9 with a prescribed means, the recessed parts 10a of the feed arm mechanism 11 support the wire (a) with arraying at the same height similarly to the recessed parts 10. When the wire (a) is supported to the recessed parts 10a, a clamp 14 integrated in a pressing cylinder 13 is descended from above for the most front line wire (a), the wire (a) is pressed/held to prevent its movement. |
