Abstract

PURPOSE:To inhibit stationary arc discharge and wire break by controlling the discharging capacitor charging voltage below the discharge starting voltage with the gap deionization characteristic immediately after discharge. CONSTITUTION:When spark discharge between wire 5 and workpiece 6 terminates and the charges accumulated in a discharging capacitor 2 are lost, the transistor 4 is energized intermittently by an output signal from an NAND circuit 12 and the discharging capacitor 2 is charged by a DC power source 1. This charging operation causes a gradual increase of the terminal voltage of the capacitor 2, but since the charging current is intermittent, its rising curve won't come above the gap dionization characteristic curve. When the charged voltage of the discharging capacitor 2 reaches a predetermined level, the transistor 4 is disenergized by the output of a comparator 11 to stop charging of the capacitor 2.
