Abstract

PURPOSE: To provide a pulse arc welding machine which is easy to form pulse waveforms, is small in power source capacity and permits setting of a capacitor at low withstand voltage by connecting a capacitor for forming pulsewaveforms between the output terminals of a DC power source.
CONSTITUTION: A wire 10 is fed 11 in the direction of base metals 12; at the same time, switching elements 5, 6 are turned on by control circuits 14, 15, to generate the arc between the wire 10 and the base metals 12, whereby the base metals 12 are welded. Base current is detected 92, and the element 6 is turned on and off by the circuit 15, so that the base current is fixed always at an approximately constant value. Pulselike current is detected 91, and the element 5 is turned on and off by the circuit 14 so that the peak current values attains a prescribed value and so that the correct pulse periods are obtained according to the feed speed of the wire 10. Immediately after the elements 5, 6 are turned on and off, the current is reflowed by way of a flywheel diode 81 or 82, a DC reactor 71 or 72, the wire 10, the welding arc 13 and the base metals 12.
