Abstract
An arc welding system of a consumable electrode type comprises: a wire feeding device that feeds welding wire from a wire feeding source to a welding torch; and a power supply device that supplies electric power between the welding wire fed to the welding torch and a base material, the system being configured to weld the base material by arc generated by the supplied electric power. The wire feeding device is provided with: an intermediate wire feeding source that is disposed between the wire feeding source and the welding torch and is configured to temporarily accommodate the welding wire fed from the wire feeding source and to feed the accommodated welding wire to the welding torch; a pull-out feeding part that feeds the welding wire at the wire feeding source to the intermediate wire feeding source; and a push-out feeding part that feeds the welding wire accommodated in the intermediate wire feeding source to the welding torch.
