Apparatus for electro-erosive cutting. A cathode in the form of a wire advances through at least one wire guide, with one guide being upstream and the other, if any, downstream of the workpiece in terms of the direction advanced by the wire. The at least one wire guide is an open, specifically a notched, wire guide, one that does not surround the wire, that is, and has associated with it a closed wire guide, specifically a wire guide in the from of a torus that surrounds the wire.
