Abstract

PURPOSE: To provide a DC power source for welding having stable arc characteristic, by connecting a series circuit consisting of a prescribed reactor and a prescribed capacitor on output side of a DC power source so as to decrease DC output ripple ratio.
CONSTITUTION: The power source comprises a single phase, 60 Hz power source 1, a transformer 2, a full wave rectifier 3, which rectifies the AC voltage obtained by boosting the output voltage of the source 1 by the transformer 2, and which is equipped across both output terminals thereof with a series circuit consisting of a reactor 4 and a capacitor 5, the series circuit resonating with a frequency (240 Hz) two times the output ripple frequency (120 Hz) of the full wave rectifier 3, an arc terminal 7 attached at the reactor side terminal of the series circuit 4,5 through a DC reactor 6 for regulating dynamic characteristic, and an arc terminal 8 attached at the condenser side terminal, so that an arc is produced across a pair of terminals 7,8. Suitable selection of the inductance of the reactor 4 and the capacitance of the capacitor 5 allows to decrease DC output ripple ratio effectively.
