WIRE FEEDING MECHANISM AND ARC PROCESSING SYSTEM EMPLOYING THE SAME

摘要

A wire feeding mechanism includes feeding rollers and a cushioning mechanism. The feeding rollers feed a wire, which is drawn from a wire supply source, along a predetermined feed path. The cushioning mechanism is arranged between the wire supply source and the feeding rollers. The wire has an intermediate portion that extends from the wire supply source to the feeding rollers. The cushioning mechanism applies tension to the intermediate portion while the length of the intermediate portion is changing.
