    摘要: The disclosed electrostatic coating system (1) includes a spray gun (2) for electrostatic coating, a high-voltage generator (5), and an alternating-current source unit (4), and further includes a removable grounding member (7), in a state attached to the main body of the gun, provided to close an open-circuit portion (3c) of the grounded power source line (3a), and a control circuit (8) for controlling the alternating current source unit (4) by detecting the current flowing through the power source line (3) or the voltage of the power source line (3) by a current coil (13) to stop application of the alternating voltage (Vac) to the high-voltage generator (5) when the detected electric current or the detected voltage has dropped or either the current or the voltage is not detected during supply of the alternating voltage (Vac) to the high voltage generator (5) of the spray gun (2). This system enables prevention of charging of the removable grounding member (7) to improve the safety in the coating operation.
