完全に自動制御することは困難であった。Conventional Structure and Problems Conventionally, when controlling various control items of a welding power source from an external remote location, one signal line has been used for each control item, as shown in FIG. Note that 1 is a main body of a welding power supply device. For this reason, as the number of control items in remote locations increases, the number of required signal lines increases, resulting in complexity, high cost, and reduced reliability. For this reason, in the past, only main control items such as welding current value and welding voltage value settings were controlled externally from a remote location, and other detailed control items were set using a switch installed on the front or inside the welding power source. Normally, the switching was done manually, and it was difficult to completely automatically control each control item of the welding power source from a remote location.
