Selects nozzle to accommodate size of wire to be melted and sprayed and screws nozzle into place on metallizing gun. Inserts wire into rear of gun and through feed rollers and nozzle. Connects hoses from gun to air compressor and tanks of oxygen and fuel gas, such as acetylene. Turns knobs to synchronize speed of wire feed, air pressure, and flow of oxygen and fuel indicated on dials to specifications computed from data charts. Ignites gases to melt wire and presses button or trigger to release compressed air which atomizes and sprays molten metal onto workpiece.
