ABSTRACT:
In a hand held electrostatic type spray coating gun a removable cartridge lengthens the paint supply conduit between the base of the grounded handle and the barrel so that the gun can be used to spray paints which have moderate electrical conductivities such as those containing metallic particles. The cartridge includes a Teflon tube in the form of an elongated spiral. Fluid connections at each end of the cartridge allow the cartridge to be easily removed and stored, and a straight conduit substituted for it when it is not needed, for example when the gun is to be used for nonconductive paints. The location of the cartridge facilitates removal, and combines with the gun to provide a well balanced device for hand held operation.
