How is the applied voltage pre-set?
A2. The voltage required is pre-set manually on the unit to a minimum level determined by the thickness of film of the coating product and its generic type i.e.: Rubber, Vinyl, Epoxy etc. Detailed instructions are set out in the unit Operator Handbook. It is important to follow these instructions in setting voltages as some surfaces have a much higher dielectric strength than others – consequently offering a high resistance to the conduction of electricity. Applied test voltages should only be sufficient to detect faults, otherwise overstressing of the dielectric strength may occur with possible surface rupturing.
