Abstract
The present invention provides an electrostatic spraying device which includes a primary charge return path between the device and the target to be sprayed and circuitry for warning the operator of potentially hazardous spraying conditions. More particularly, the present invention includes circuitry for warning the operator of conditions wherein the primary charge path is inadequate and other conditions in which the return of spray current via the primary charge path is affected.
