ABSTRACT:
A spray gun for electrostatic painting in which an external electrode sustaining a high voltage can be fixed/removed while sustaining insulation from a spray unit on the ground potential side by limiting current supply to paint appropriately when electrostatic painting is performed using conductive paint, e.g. water based paint, and safety and handling performance are enhanced while ensuring the painting efficiency as the spray gun for electrostatic painting. On the outside of the spray gun (1) having the spray unit (5) at the forward end thereof, the external electrode (7) having an electrode projecting from the forward end part thereof is provided removably at the part (13) of the gun body being connected with the electrode while being separated from the paint passage such that it can be replaced readily. The part being connected with a high voltage output end part through a high resistor for limiting current can be shortened while sustaining safety by providing a turn-up part so that a sufficient creeping discharge preventing 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 is composed of a flexible resilient material in order to prevent damage.
