According to the inter-electrode state distinguished by the electrical discharge state distinguishing circuit (6), in cases where the inter-electrode state is that of electrical shorting (Y1), the inter-electrode current waveform control means supplies a triangular wave current (I) to the electrodes, and in cases where the inter-electrode state is that of normal electrical discharge (Y3), it supplies a trapezoidal wave current (I) to the electrodes. Breakage of the wire electrode (E) can be avoided and machining speed can be improved.

摘要： Charge accumulated in a capacitor is used to provide a processing current flow between a target and an electrode. When a diode is turned on, a first dc power supply is used to provide the processing current flow between the target and the electrode. In this state, after a lapse of a predetermined time, the current supply using the first dc power supply is stopped, and an induced electromotive voltage, induced by two floating reactors, is used to rapidly drop the processing current flowing between the target and the electrode, while charging the capacitor.
