Abstract
The electric power unit for machining of a wire electric discharge machine includes an electric discharge state discriminate or () for discriminating a state of electric discharge generated between the electrodes and an impression voltage selecting means () for inverting the polarity of the electric discharge inductive pulse voltage from the previous electric discharge inductive pulse voltage when an electric discharge state between the electrodes is discriminated to be abnormal (Y) or open (Y) and for making the polarity of the electric discharge inductive pulse voltage to be the same as the polarity of the previous electric discharge inductive pulse voltage when the electric discharge state between the electrodes is discriminated to be normal (Y).
