Abstract
A power supply component for cutting a wire electrode of an electroerosion machine having a core of hard metal and about it a layer of an electrically conductive material, which is softer than the core. Within a relatively short time, when the machine is in use, the wire cuts a notch in the soft layer, the notch acting as a wire guide. As soon as the notch reaches the harder material of the core, the hard metal prevents any further notch deepening.
