ABSTRACT:
The invention concerns a method and a circuit arrangement for electrically driving print electrodes in an electroerosion printer by means of driver stages producing relatively strong and relatively short ignition pulses as well as by means of driver stages producing relatively weak burning pulses which are of longer duration than the ignition pulses. The burning pulse is first initiated and if an arc is struck, the ignition pulse is not required. Use of the burning pulse alone produces a sharp edge printing mark. Only if the burning pulse is unable to strike an arc is the ignition pulse delivered to assure that printing occurs.
