Zinc Spray Gun

Zinc Spray Gun Operation

Except for combustion, all functions of the Zinc Spray Gun are powered by air pressure and flow. Air pressure drives the turbine and wire to drive the mechanism. Enables the wire grip mechanism to feed the wire, cools the nozzle and air cap, and propels the atomized material onto the subject workpiece surface. It is essential that proper air pressure and flow is maintained to the spray gun during operation. Once the turbine is marked speed, the driveshaft and lower drive roll and gear are turning. The speed of the turbine is controlled by rotating the control ring as indicated (i.e., FASTER, SLOWER). Opening the wire feed valve on the handle actuates a wire grip mechanism. This engages the upper and lower drive gears to grip and feed a wire. The wire extends beyond the front of the air cap where it's fully melted and sprayed.

Combustion of Zinc Spray Gun

The oxy-fuel gas doesn't have enough energy, even after combustion, to propel the melted material. When the thermal spray gun is initially ignited (with the gas head valve in the lighting position), there is no air flowing to the front end. Immediately after the gas is ignited, the gas head valve is set to the run position. The oxygen and combustion gases flow at optimum levels for sustained combustion and air flows to the air cap.

The airflow to the air cap maintains an air envelope around a flame and a melting wire. The air envelope cools the front end parts, prevents the loading of material on the air cap, and propels the melted material onto the substrate.
