IGNITION APPARATUS FOR ARC SOURCES

摘要

The present invention relates to an ignition device for igniting a high-current discharge of an electrical arc evaporator in a vacuum coating system. Ignition is performed by means of mechanically closing and opening a contact between the cathode and anode. Contact is established by means of an ignition finger which can move on a forced path. On account of the forced path, the ignition finger can be moved to a park position, which is protected against coating, by means of a simple mechanical drive and said ignition finger can also be used to ignite a second target.
