Abstract

The spray coating device has a HV generator (12) for supplying at least one HV electrode (10) of a coating spray (2), with regulation of the electric current carried by the coating material between the coating spray and the coated object, using a regulator (16) with current and voltage limitation functions, supplied with the measured current value by a measuring circuit (24) connected in a feedback path between the coated object and the regulator.
