<p>An electrostatic coater with a power transmission frequency adjuster capable of automatically adjusting the power transmission frequency so as to control the consumed current flowing through a high-voltage step-up circuit to a predetermined value or less. The electrostatic coater has a high-voltage step-up circuit (201) provided in an electrostatic spray gun (2) and generating a dc high voltage for electrostatic coating by rectifying a high-frequency low voltage, a high-frequency low-voltage generator (1) provided separately from the electrostatic spray gun and generating a high-frequency low voltage, a low-voltage cable (3) for interconnecting the high-frequency low-voltage generator and the high-voltage step-up circuit, current sensing means (111) for measuring the current corresponding to the consumed current intrinsic to the high-voltage step-up circuit, and frequency control means (107, 112) for adjusting the frequency of the high-frequency low voltage so that the current measured by the current sensing means may be a predetermined value or less.</p> |
