Even if the distance between the tip of the electrostatic gun and the object being coated changes, the coating process can be safely and reliably completed without stopping the coating process. [Solution] The electrostatic painting system comprises an electrostatic gun and an electrostatic controller that controls the voltage output from the electrostatic gun. The electrostatic controller monitors the output voltage and output current of the electrostatic gun and can switch between constant voltage control, which maintains the output voltage constant, and current limiting control, which limits the output current to a range that does not exceed the current value at which sparks occur. Furthermore, if the output current exceeds a preset first current threshold while constant voltage control is being performed, the controller switches to current limiting control. If the output voltage exceeds a preset voltage threshold while current limiting control is being performed, the controller applies a pulse voltage set to a voltage with an absolute value greater than the voltage threshold. If the output current at the time of pulse voltage application is less than a second current threshold set to a value less than the first current threshold, the controller switches from current limiting control to constant voltage control.
