Abstract:
1. An electrostatic coating system which includes an electrostatic coating spray gun atomizing an electrically charged coating material and applying the atomized coating material to an object to be coated and an alternating-current (AC) power supply generating alternating voltage, the electrostatic coating spray gun comprising: the AC power supply comprising: wherein the AC voltage supply line includes a ground side supply line which is grounded, the ground side supply line including a part formed with an open circuit; wherein the grounding member is configured to close the open circuit when attached to the gun body; and wherein the control unit is configured to stop supply of the AC voltage to the voltage generation unit when the detected current or the detected voltage is reduced while supplying the AC voltage to the voltage generation unit or when the current or the voltage is not detected.
