Abstract

PURPOSE:To prevent a wire electrode from snapping off and to increase a work feeding speed, by changing electric conditions of discharge when an average working voltage or current reaches a prescribed reference value. CONSTITUTION:When discharge machining is performed between a wire electrode 1 and a workpiece 2, the voltage of the spark is averaged by an LPF 10. The averaged voltage is applied to comparators 11H, 11L so that the averaged voltage is compared with reference voltages. The outputs of the comparators 11H, 11L are applied to an electric condition controlling circuit 12 to supply an output to change the electric conditions of a working power supply unit 3.
