The present invention relates to a welding device controlling device and, more specifically, to a welding device controlling device capable of preventing the distortion of control signals due to a high current of a welding power line and remarkably reducing the number of control wires. The welding device controlling device including a welding device control unit receiving manipulation signals of a switch; a control communication code converting unit converting the control signals according to the manipulation signals of the switch inputted into the welding device control unit; a control communication code joining unit joining a control communication code converted by the control communication code converting unit with a feeder driving power source to operate a welding wire feeder using an alternating current wave form; a communication code detecting unit detecting a control communication code from the feeder driving power source inputted into the welding wire feeder; and a control signal converting unit converting the control communication code detected by the control communication code detecting unit. |
