PROBLEM TO BE SOLVED: To provide a wire feeder having a wire straightening mechanism for straightening the curliness of a wire and achieving stable wire feeding performance without damaging the wire inserted through the wire straightening mechanism.SOLUTION: The wire feeder for feeding a welding wire includes: a spool shaft for mounting a wire spool wound with the wire; a wire straightening mechanism part having a plurality of straightening rollers for straightening the curliness of the wire pulled out of the wire spool; a feed roller and a pressure roller for holding and feeding the wire having passed through the wire straightening mechanism part; a motor for rotating the feed roller; and a frame part for mounting the wire straightening mechanism part. The wire straightening mechanism part is mounted to be rotatable around a wire feeding direction used as a rotation axis with respect to the frame part and to be movable in an oblique direction to the wire feeding direction. |
