Arc Spray Equipment
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.
Anti-corrosion or engineering coatings can be applied by arc spray and changing between the two is quite simple.
Arc spray systems are commonly considered to be easy to operate and also to automate.
Metallisation have a full range of arc spray systems for hand-held and fully automatic / robotic applications.

FAQs About Arc Spray
The process where by 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.
