Abstract
In a wire cut electric discharge machine, an apparatus is provided, which is capable of detecting completion of wire setting with a simple construction when a wire electrode (W) is automatically extended. Electric power is supplied to the wire electrode (W) from an electric power supplying section (43) through a contact (32) during automatic wire setting. When the wire electrode (W) is fed and brought into contact with an iron plate (44) disposed at a side at which the wire electrode (W) is taken out, an electric potential at the iron plate (44) of the electric power supplied section increases, to thereby detect completion of wire setting.
