In a wire electric discharge machine, a discharge delay time is used to classify the inter-electrode state into three categories; a short-circuit state, small-gap state, and large-gap state. Based on this classification, the magnitude of a machining current supplied from a main discharge circuit is determined. If the discharge delay time is zero (i.e., if no electric discharge is generated) after the lapse of a predetermined time since the start of the application of a machining voltage to an inter-electrode gap by an auxiliary discharge circuit, the inter-electrode gap is determined to be short-circuited by machining chips. Thereupon, a short-circuit machining current is supplied from the main discharge circuit to the inter-electrode gap to remove the machining chips. In this way, establishment of a complete short-circuit state is prevented so that the machining efficiency is improved to increase the machining speed.
