摘要：A spray gun for electrostatic painting in which an external electrode sustaining ahigh voltage can be fixed/removed while sustaining insulation from a spray unit on theground potential side by limiting current supply to paint appropriately when

electrostatic painting is performed using conductive paint, e.g. water based paint, andsafety and handling performance are enhanced while ensuring the painting efficiency asthe spray gun for electrostatic painting. On the outside of the spray gun () having thespray unit () at the forward end thereof, the external electrode () having an electrodeprojecting from the forward end part thereof is provided removably at the part () of thegun body being connected with the electrode while being separated from the paintpassage such that it can be replaced readily. The part being connected with a highvoltage output end part through a high resistor for limiting current can be shortenedwhile sustaining safety by providing a turn-up part so that a sufficient creeping dischargepreventing distance is ensured up to the exposed part on the outer surface. Furthermore,the electrode body itself is simplified so that it can be replaced with one touch, and it iscomposed of a flexible resilient material in order to prevent damage.
