PURPOSE: A wire guiding device of a wire cut electrospark machine is provided to increase lift of usage by accurately performing a position moving work for repeatable usage when a wire connection part of a power feed dies is worn out. CONSTITUTION: A wire guiding device(100) of a wire cut electrospark machine comprises a main body(104), a movable block(107), a power feed dies mounting unit, a power feed dies(109), a power feed dies position control unit, and an actuator. The power feed dies comes into contact with a wire(101) passing through the movable block and supplies electricity. The power feed dies position control unit moves a surface which is not worn out to a position corresponding to a wire when the power feed dies is worn out by the wire. The power feed dies position control unit comprises a rack gear(113), a pinion(114), and a rotation knob(118).
