PURPOSE:To decrease the inductance of a discharge circuit, by causing mutually inverse currents to flow through a parallel conductor wire assembly. CONSTITUTION:Mutually inverse currents are caused to flow through adjacent unit conductor wires 36a, 37a, so that the magnetic force lines of magnetic fluxes produced by the currents flowing through the conductor wires cancel each other. The inductance due to the magnetic force lines is thus decrease. A section not shown provided with a swithcing unit comprising a charge/discharge capacitor 29, a transistor 30, etc. is placed near a machining gap, so that the speed of machining is increased. |
