Abstract: PURPOSE:To eliminate useless control by holding peak voltage values within each defined period determined by first and second peak holding means, comparing them by a voltage difference comparing means and judging whether a short circuit is one which must be truly detected for an electric discharge machining. CONSTITUTION:As signals are inputted into a terminal 2 during a period from the application of discharge pulses to an end, an FET 6 is turned on and a discharge pulse voltage inputted from a terminal 1 is charged into a capacitor 10 and a peak voltage value is held by a peak hold circuit 14 formed with an operating amplifier 12. Also, as signals are inputted into a terminal 3 during a period from when a time in which normally discharge is supposed to be under way after the application of discharge pulses elapsed to the end, an FET 7 is turned on and, equally, a peak voltage value is held by a peak hold circuit 15. And, a difference voltage between both is outputted from an operating amplifier 16 and compared with a reference voltage V5 which is larger than the difference voltage of a complete short circuit period by an operating amplifier 17, and only a complete short circuit period is distinguished and detected. Thereby, useless control can be eliminated preventing the lowering of machining efficiency.
