PROBLEM TO BE SOLVED: To provide a welding system capable of performing communication exactly as far as possible without providing a control line between a welding power source device and a wire feeding device.SOLUTION: A welding system A1 includes: a welding power source device 1; a wire feeding device 2; a welding torch 3; and power cables 41, 42 for supplying power for welding to the welding torch 3 from the welding power source device 1. Therein, power transmission lines 51, 52 for supplying the power for driving a feeding motor 24 that the wire feeding device 2 has from the welding power source device 1 to the wire feeding device 2 are provided, so that the welding power source device 1 and the wire transmission device 2 perform communication with each other via power transmission lines 51, 52. The power transmission lines 51, 52 have less overlapped noise as compared to power cables 41, 42. Accordingly, communication can be performed more exactly compared to a case when communication is performed via the power cables 41, 42. |
