It is important that hanging racks be properly maintained to assure good electrical contact with parts being painted and the conveyor. AU parts should be painted in prescr

Manufacturing Staff Febnurry, 1979 mnr m U.S. aweekly (or-more frequent) check shallbe made of sU hoods, fe

A power pack and spray gun are used for this test. (See Sketch 6.) For convenience, one of the spare power packs should be modified by wiring-out the a
