WIRE SUPPLY MECHANISM, WIRE FEED DEVICE, AND ARC SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a wire supply mechanism which can reduce a radial load applied on a feed member.SOLUTION: A wire supply mechanism includes: a feed member 53 having a feed roller 535 rotating in a first direction; a press member 54 having a press roller 545 rotating in the first direction; and a load reducing member 55 having a load reducing rotation body 555 rotating in the first direction. The feed member 53 includes a rotation shaft of the feed roller 535 extending in the first direction. The press roller 545 applies force F1 toward a second direction X2 orthogonal to the first direction on the feed roller 535 in a state where a wire 891 is sandwiched with the feed roller 535. The load reducing rotation body 555 applies force F2 toward a third direction X3 on the feed member 53.
