ABSTRACT:
An arc suppressor is disclosed which includes at least one cartridge having a housing formed with a first end carrying an electrode, a hollow interior and a second end which mounts a cylinder whose piston head is axially movable within the interior of the housing. The electrode of the cartridge and the metal body of the cylinder are each electrically connected by wires to respective grounded and electrostatically charged elements of the voltage block device associated with a system for supplying electrically conductive coating materials. The piston head of the cylinder is caused to move proximate the electrode carried by the housing sufficiently in advance of the movement of the grounded and charged elements of the voltage block device toward one another so as to induce the formation of an electrostatic discharge or arc within the interior of the cartridge instead of between the elements of the voltage block device.
