Zusammenfassung:	A wire feeding device (4) that feeds welding wire (W) from a wire feeding source (3) to a welding torch (13). The wire feeding device (4) is provided with: an intermediate wire feeding source (41) that is disposed between the wire feeding source (3) and the welding torch (13) and is configured to temporarily accommodate the welding wire (W) fed from the wire feeding source (3) and to feed the accommodated welding wire (W) to the welding torch (13); a pull-out feeding part (41d) that feeds the welding wire (W) at the wire feeding source (3) to the intermediate wire feeding source (41); and a push-out feeding part (42) that feeds the welding wire (W) accommodated in the intermediate wire feeding source (41) to the welding torch (13).
