Abstract
A wire-electrode arrangement for effecting a spark-erosive cutting and a method for the manufacture of a wire electrode. In order to be able to cut non-conductive materials, a plus potential and also a minus potential can be applied to the electrode, since the wire electrode is formed by a first and a second electrode, which are insulated from one another and which extend substantially parallel to one another.
