ABSTRACT:
An electrostatic powder-coating gun is provided which comprises a powder duct which is connected to a supply conduit for a powder-air-mixture and arranged along the longitudinal axis of the gun barrel and having an open mouth towards the work to be coated, a high-voltage generator, an electrode supporting tube extending through the powder duct in axial direction thereof, and a high-voltage electrode located on the supporting tube and protruding beyond the mouth of the powder duct towards the work. The high-voltage generator and the powder duct are disposed in series along the longitudinal axis of the powder tube in such a way that the powder duct is adjacent the muzzle of the gun barrel. The powder duct is comprised of a toroidal duct and an annular channel extending therefrom and opening to the outside.
