USPTO Abstract
A coating of positive ions is applied to a substrate by generating an arc at a cathode, directing a beam of ions emitted from the cathode to the substrate via a filter path to remove macroparticles, igniting the arc by moving an arc ignition from a retracted position to an ignition position in which cathode contact is made, and storing the position in which arc ignition occurred.
