PROBLEM TO BE SOLVED: To reduce a communication cable of a long range in welding equipment.SOLUTION: Welding equipment 1 includes a welding power source device 10. The welding power source device 10 includes a power source part 12 for supplying voltage and current to a welding torch 140, a power line carrying communication part 18 for communicating to superpose communication signals on a power cable 160 supplying the voltage and the current to the welding torch 140 from the welding power source device 10, a wireless communication part 16 for receiving information inputted to a remote controller 120 carried by a welding worker wirelessly, and a control part 14 for setting a welding parameter in the power source part 12 on the basis of the information given via any one of the power line carrying communication part 18 and the wireless communication part 16. Thus, the communication cable can be reduced and reliability of wireless communication can be improved. |
