Abstract
An electrostatic spray gun is provided that alternatively houses an end section of a high voltage cable remotely supplied by a high voltage source or an internal voltage multiplier so the electrode of the gun may be alternatively powered by the high voltage output of the end section of the high voltage cable or the internal voltage multiplier. The gun has an internal chamber into which the internal voltage multiplier or end section of the high voltage cable may be alternatively placed. A resistor/electrode assembly is mounted onto the high voltage output of the internal voltage multiplier or end section of the high voltage cable. A retainer secures the internal voltage multiplier or end section of the high voltage cable within the internal chamber and also maintains the electrical contact between the resistor/electrode assembly and the high voltage output housed within the internal chamber. The internal voltage multiplier and end section of the high voltage cable are configured relative the internal chamber to prevent rotation so that electrical contact between the resistor/electrode assembly and the high voltage output housed within the internal chamber is further maintained.
