Devices for electric spark processing a spark circuit containing a copper electrode in which a switching element reducing the wear of the electrode is connected, characterized in that this switching element is formed as an inductance (7) and a capacitor (2) connected in series with this and bridged with a resistor (1), so that when the spark circuit is fed unipolar impulses are formed with direct current and this leads to a reduction in electrode wear.
