Abstract
PURPOSE: To improve the finish after welding and to reduce arc sound by providing a secondary winding to a reactor, and providing a control element which is energized at the rise and fall of a current waveform by opening and closing said secondary winding during pulse periods.
CONSTITUTION: In pulse periods, the switching element of a pulse power source part 1 is on and a reactor control circuit 8 emits an on command as well thereby turning a switching element 7 on. A secondary winding 6 of a reactor closes and the apparent inductance of the reactor is small. When the pulse current attains a peak value, the circuit 8 emits an off command to turn the element 7 off. Then, the secondary winding 6 opens and the inductance value increases. If the element in the part 1 is turned off, the electromagnetic energy of a reactor 3 flows through a reflux diode 5. Therefore, the peak value decreases considerably and when it decreases down to a constant value, the element of the power source part again goes on.
