装置。 In an electric discharge machine that connects a machining power source and a switching element to the gap formed by the workpiece facing the electrode, and performs machining using a pulse current by controlling on/off of the switching element, the switching element is a MOSFET type. When connecting transistors in parallel, an overcurrent protection alarm fuse is added for each configuration of MOSFET type transistors connected in parallel to the current limiting inductance, and a switching circuit is created by adding a circuit to control by a fuse blown alarm. A power supply device for electrical discharge machining that is configured to prevent the spread of damage to elements.
