Abstract:
An electrostatic painting device comprising;an electrostatic painting machine having a high voltage generation part adapted to supply high voltage to atomized paint material; detection means for detecting load current flowing between an electrode of said high voltage generation part and an article to be coated, wherein the load current varies depending on a change of a spray distance between said electrostatic painting machine and the article to be coated; processing means for outputting an alarm signal when a detected load current falls below a threshold load current value, which corresponds to a maximum distance within an optimum distance range of said spray distance; wherein the threshold load current value, corresponding to the maximum distance, is determined for the electrostatic painting, device in consideration of a relationship between the spray distance of the electrostatic painting machine and the load current; and alarm means for receiving the alarm signal and providing an alarm display.
