Arc spray or 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.
Heat Source: Electric arc
Material: Wire
Transfer: Compressed air
Process: Two wires 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 work piece.
In response to feedback from customers for a flexible system but with higher throughput, Metallisation have created the 500Amp, ARC150/S500-CL arc spray system. The ARC150 system offers a great balance of controllable throughput with flexible operation and the opportunity to have extended supplies packages up to 50m from the energiser to the pistol.
A number of new features are included to enable reliable spraying at 500A, 100% continuous duty cycle. These include a new pistol front end with contact tips instead of solid tubes; uprated supplies / cooled conductors and terminals; a heavy duty drive unit with new, v-shaped rollers; heavy duty flexible drive and a new 500A energiser with high specification digital meters. These features combine to give a flexible, reliable and manageable solution for medium and large scale thermal spray applications, producing quality, fine surface finish coatings.
The ARC150 system is designed for anti-corrosion applications spraying zinc, aluminium and their alloys but can also be used to spray other materials commonly sprayed in larger applications such as high temperature alloys.
Key features
The MEC 96/600 system is a 3 phase, 600 amp arc spray system with 5 metre pull via a pneumatic drive in the pistol. It can be set up to spray 1.6mm engineering wires or 2.3mm anti corrosion wires.
The TMS Bridgemaster is a heavy duty, lightweight, low energy, high deposition arcspray system for applying metalized coatings. Designed for shop or field applications, the Bridgemaster is a proven workhorse in any environment. Meters and controls are conveniently located on the feeder providing "at the workplace" control. Flexibility in design allows for a wide variety of possible configurations. For shop or field corrosion control coatings, the Bridgemaster system is a formidable package. The lightweight portability of the total system, low maintenance, lightweight gun and leads, and the "no wire-clipping" feature add up to increased arc production time for the applicator. Sprays 3.2mm and 4.76mm wires, wide spray pattern, powered by single phase or 3 phase inverters or DC welding power supplies.
