1. An apparatus for electro-erosive cutting, comprising a wire cathode advancing through a wire guide located upstream of the workpiece in terms of the direction advanced by the wire, said wire guide is a closed or surrounding wire guide and shaped like a torus, and a wire-position sensor located such as to monitor the position of the wire in the torus-shaped guide.

7. A method for electro-erosive cutting with a wire cathode, comprising the steps of
guiding the wire through a closed torus shaped wire guide, monitoring the position of the wire with a wire-position sensor, and processing the results of the position monitoring for determining the position of the wire in the wire guide.

9. A method for electro-erosive cutting, comprising the steps of
advancing a wire cathode along and against an electric-current source, whereby a tension is asserted on the wire, advancing the wire through a first open V-grooved wire guide, advancing the wire along a wire-position sensor, advancing the wire through a closed torus-shaped wire guide, monitoring the position of the wire with the wire-position sensor, processing the results of the position monitoring by determining the position of the wire in the closed wire guide, advancing the wire through the workpiece, and advancing the wire through a second open V-groove wire guide.
