Current supply device for movable electrodes of spark erosion machines

A current supply device for movable electrodes of spark erosion machines, comprising a plurality of current supply contacts arranged in series in a direction of elongation of a movable electrode and connected by leads to a current supply source;

• and a plurality of electrical components interconnected in said leads between said current supply contacts and said current supply source, said electrical components being constructed and wired in said leads in such a way that partial currents fed in at individual current supply contacts are of the same magnitude, taking into consideration of a voltage drop along said electrode, wherein the electrical components interconnected in the leads are dimensioned so as to bring about an inductive negative feedback of the partial currents.
