A wire-cut electroerosion apparatus comprising a work tank (6) for containing a dielectric fluid, the tank having at least one wall with an opening (36) therein, and a lower arm (15) which is supported at one end on the outside of the work tank and extending through the opening into the tank, the tank being movable relative to the lower arm. The work tank includes a base container member (12) and at least one movable frame member (13,14). The base container member includes a rear wall with the above-noted opening therein and a low wall formed along the other three sides, the low wall being lower than the bottom of the workpiece. The movable frame member(s) can be raised and lowered using a pantograph (20) to thereby easily access the workpiece and electrode wire.
