PCT No. PCT/JP92/01691 Sec. 371 Date Aug. 30, 1993 Sec. 102(e) Date Aug. 30, 1993 PCT Filed Dec. 24, 1992 PCT Pub. No. WO93/13902 PCT Pub. Date Jul. 22, 1993.An immersion type wire cut electric discharge machine is provided with a sealing structure for sealing a gap between a machining liquid tank and a lower arm while permitting movement of the tank relative to the arm, and nozzles for preventing sludge from adhering to the inner surface of a slide member of the sealing structure. A slide seal includes a slide plate through which the lower arm extends. A guide mechanism for guiding the slide plate while keeping the plate in close contact with a tank wall of the machining liquid tank is formed in the tank wall, through which the lower arm extends. The nozzles are arranged inside the machining liquid tank and inject fluid toward the inner surface of the slide plate.
