Abstract
PURPOSE: To supply pulse current from a transformer and a capacitor and decrease the capacitor of the transformer by connecting the connection point of a diode connected to the transformer and a phase control element to earth side via the capacitor.
CONSTITUTION: When a phase control element 2 turns on at the welding, pulse current flows from a transformer 1 and a capacitor 5 to the arc part 9 of an external circuit B through the element 2. Next, the phase of the output voltage of the transformer inverts to apply reverse voltage upon the element 2 which switches off to stop the current, then base current flows to the circuit B through a base power source 3. When a switch 7 is turned on during this switch off period, the capacitor 5 is charged through a current control element 6. If the element 2 is again turned on at a prescribed phase after turning the switch 7 off to stop the current flowing from the element 6, the pulse current again flows from the transformer 1 and the capacitor 5. In this way, the pulse current is supplied from both the transformer 1 and the capacitor 5.
