Abstract
The apparatus (1) includes a wire-preparation (18) section upstream of the erosion point (3). Surface plating, especially with zinc, tin, and/or silver, and/or non-metal protective coating is removed from the wire while the wire is being prepared and especially while it is being cleaned and surface-treated. Substances, especially substances already present at the surface of the wire, are thermally diffused throughout that surface.
