Abstract
An electrostatic spray coating gun has an improved high voltage charging system which includes a flexible and resilient electrode in the form of an elongated coil spring. This form of electrode substantially eliminates the likelihood of scratching or puncturing the skin of an operator or repairman, and allows the electrode to return to its proper orientation after being bumped, while exhibiting good paint charging characteristics for use in electrostatic spray coating.
