Power supply device for arc processing and method of controlling power supply device for arc processing

摘要

Driving and stopping of a plurality of inverter circuits (INV1, INV2) are controlled by the inverter circuits (INV1, INV2) according to the measured values of the temperatures of the switching elements constituting the inverter circuits (INV1, INV2) and the set values related to the output current. Select to reduce power consumption.
