Abstract

PURPOSE:To prevent a drop in machining surface accuracy due to the change of no-load voltage on the fluctuation of electrolytic voltage and the like, and enable uniform machining by providing a clamp circuit for clamping the no-load voltage between a wire electrode and a workpiece to the predetermined value. CONSTITUTION:A continuous line waveform is such that machining gap voltage A does not exceed clamp voltage Ec, because a clamp diode 21 is electrically energized when the voltage Ec is set to the predetermined level and the machining gap voltage A is caused to be equal to or above the Ec voltage level due to the change of electrolytic voltage and the like. As a result, the machining gap voltage A (no-load voltage) is kept constant at the time of no load and machining accuracy is improved, thereby making a uniform machining surface available. In this case, the aforesaid system applies with the value of machining source voltage so set that the machining gap voltage A is equal to or above the set voltage Ec (clamp voltage) due to electrolytic current.
