Arc Spray Equipment

Arc Spray Systems for Optimal Coating Solutions

Arc spray (sometimes referred to as twin wire arc spray) is a process that uses an electric arc to melt wires. The molten metal is then atomised with compressed air to create a spray stream that applies the coating onto the surface being sprayed. The resulting coating offers exceptional corrosion resistance, thermal protection, and wear resistance.

Anti-corrosion or engineering coatings can be applied by arc spray and changing between the two is quite simple.

Our arc spray systems are easy to operate with clear controls and reliable performance. With our focus on efficiency, you can expect quick coatings with minimal material waste, making it not just a powerful choice, but an economical one too.

FAQs About Arc Spray

The process whereby two wires (hence a common term for the process is Twin Wire Arc Spray), are fed into the pistol and electrically charged, one positive and one negative.

The wires are forced together and form an electric arc, melting the wire. Compressed air, passing through a nozzle, atomises the molten metal and sprays it onto the workpiece. There are three methods of wire feeding, push, pull and push/pull. The higher the current rating of the system, e.g. 350A, 700A etc., the higher the spray rate.
