手段を備えてなるアーク加工用電源。 In a power source for arc processing, the DC power obtained by converting AC power into DC power by a capacitor input type rectifier circuit is converted into power having desired characteristics by an output control circuit using a microcomputer. A parallel circuit of a contact of a magnetic contactor and a current limiting resistor is connected in series between the AC input terminal and the rectifier circuit, and the output control circuit is activated by turning on the AC power and the electromagnetic contactor is activated. A power supply for arc machining, comprising a main power supply delay means that closes the contacts of the machine by a signal outputted when a set time period elapses from the microcomputer that starts counting from the time when the AC power supply is supplied.
