Abstract

PURPOSE:To control a working gap, by classifying spark waves according to the spark conditions and putting different wave in a servo circuit in accordance with the conditins. CONSTITUTION:Wave forms introduced from a pulse source 1 through a conductor (a) and wave forms introduced from an electrode 4 through another conductor (b) are compared by an interpole signal processing circuit 6 to classify the spark conditions into groups of effective discharge, no discharge, shortcircuit, arc discharge and other abnormal discharge. A different wave form is put in a servo circuit 2 in accordance with the classified discharge conditions. The servo circuit 2 averages the input to compare with a standard voltage, and its output actuates the electrode 4 through an electrode driving unit 3 and controls the working gap at a constant level.
