PROBLEM TO BE SOLVED: To cope with the unexpected disconnection of a wire electrode without damaging the quality of a product by specifying the front position of a working locus of blocks including a disconnection generated position, and restarting the working from the front position of the working locus of the block after connecting the wire. SOLUTION: A wire guide and a work table are relatively moved from a disconnection generated position along the working locus so that a connected wire is positioned at a position returned by the predetermined distance from a starting position of a disconnection generated block, and positioned at a wire connecting point, and the automatic connection of the wire is carried out. Since the wire is moved to the starting position of a disconnection generated block without generating the disconnection, flashing and wire feeding are restarted. The wire guide and the work table are relatively moved along the working locus so that the wire is moved to the starting position of the disconnection generated block, and a discharge power source is turned on for restarting of the working, and the working is restarted from the starting position of the disconnection generated block.
