Patent abstract
Total supplied current (I2) and high voltage (Vm) supplied to a rotary atomizer head (5) are detected by a total current sensor (115) and a high voltage sensor (116). Total leak current (I2) in paint paths, thinner paths and air paths inside an electrostatic atomizer (2) is detected via a metal back plate (40) of the electrostatic atomizer (2). When the total leak current value (I2) exceeds a threshold value (Ia), the level Vm of the high voltage applied to the rotary atomizer head (5) is lowered stepwise.
