ABSTRACT:
A power supply apparatus for an electroerosion machine serves to carry an erosion current to a passing-through erosion wire by means of at least one contact part, said erosion wire being pressed against the contact part by means of a contact pressure device. In order to increase the erosion currents which can be carried, the contact pressure device is formed by a magnetic field generating means which applies a magnetic field to the erosion wire.
