Zusammenfassung:A wire feeding device configured to feed welding wire (W) from a wire feeding source to a welding torch is provided with: an intermediate wire feeding source (41) that is disposed between the wire feeding source and the welding torch and is configured to temporarily store the welding wire (W) fed from the wire feeding source and to feed the stored welding wire (W) to the welding torch; a first feeding part (41d) that feeds the welding wire (W) at the wire feeding source to the intermediate wire feeding source (41); a second feeding part (42) that feeds the welding wire (W) stored in the intermediate wire feeding source (41) to the welding torch; and a feed control unit (5b) that controls speed of feeding the welding wire (W) by each of the first feeding part (41d) and the second feeding part (42).
