ELECTROSTATIC PAINTING DEVICE

摘要

A total supply current I1 and a high voltage Vm supplied to a rotary atomizing head (5) are detected by a total-current sensor (115) and a high-voltage sensor (116). A total leak current I2 from a paint path, a thinner path and an air path in the painter (2) is detected via the rear-end metal plate (40) of the painter (2). When a total leak current I2 exceeds a threshold value Ia, a high voltage Vm applied to the atomizing head (5) is decreased stepwise.
