An apparatus and method for spraying molten metal that is light weight, requires low maintenance and is quick and simple to operate. A feed system is provided that uses an electric motor and control system to push the electrodes to the head and to prevent system failure, by temporarily stopping the feed, upon the occurrence of the feed wires becoming shorted or welded together. A portable head is provided that employs parallel lead guides that allows complete head manipulation without electrode mismatch. An atomizing gas nozzle is also provided that permits lower air pressure and compensates for arc wander. A lead system is provided that combines into one lead the feed wire guides, current leads and the atomizing gas. The atomizing gas also becomes a coolant allowing lighter current leads for arc metal spraying.
