A wire feeding device (18) is configured as follow. When power is supplied to an electromagnetic valve (2) of the wire feeding device (18) from an arc welding power supply device (19) and the electromagnetic valve (2) is driven, a sequence control unit (7) provided in the wire feeding device (18) and controlling a self-holding operation is also supplied with the power and operates. In addition, a first path and a second path are provided in parallel with each other, the first path being used for directly outputting the start-up signal (TS) of a start-up switch (1) to the arc welding power supply device (19), the second path being used for inputting the start-up signal (TS) of the start-up switch (1) to the sequence control unit (7) and outputting the start-up signal output from the sequence control unit (7) to the arc welding power supply device (19).
