Abstract

PURPOSE: To realize upset in a proper state of the weld surface, by integrating only the weld time of passing of current in the weld surface, and promoting the specified program control when reaching the predetermined time of integration.
CONSTITUTION: Primary (secondary) current detected by a current detector 3 is inputted into a comparator 6 through a full-wave rectifier 4 and a smoothing circuit 5, and only the flush current is outputted as difference signal. On the other hand, the pulse signal of a specified period transmitted from a pulse generator 8 passes a gate circuit 9 only when the difference signal from the comparator is inputted, so that only the pulse signals corresponding to the time of passing of flush current are integrated in digital counters 10W15. Therefore, by presetting an integrated number of pulses corresponding to a proper weld time in each counter, the specified program control may be promoted at high precision.
