Abstract
In a method of electrophoretic coating wherein a workpiece is immersed as an electrode in an electrophoretic bath, the electric current supplied to the bath is initially caused to remain substantially constant until the resistance between the workpiece and the other electrode or electrodes in the bath rises to a certain value, and thereafter the applied voltage is caused to follow a desired function of time, e.g. a linear rise with time, the electric current in the bath being sufficient to maintain electrophoretic action in the bath whilst the desired functions are followed, and such that the tendency for the current to vary as the resistance of the workpiece varies is at least partially counteracted. In an embodiment described for carrying out the regulation of current and voltage in an electrophoretic bath, the bath 1 is fed by direct current derived from a three-phase current supply system by a rectifier bridge 2, an actual value sensing arrangement 3 being situated between the bridge 2 and the bath 1, which supplies signals representative of the actual values of current and voltage supplied to the bath to a current regulator 5 and voltage regulator 6, respectively, via a converter 4 and switch 8. The position of the switch 8, which may be varied automatically by the sensing means 3, determines whether regulation of current or voltage takes place, and a setting member 7 is adjusted by the operative regulator to produce the desired value of current or voltage to be fed to the bath 1. <PICT:1047897/C6-C7/1>
