Also known as metalizing, electric arc thermal spray coating coats metal on product surfaces. The metallic coatings can serve protective, decorative or functional purposes. This type of coating is known for longevity, durability and versatility. Thermach Electric Arc systems are designed to lower operator fatigue and significantly reduce maintenance costs.


Electric Arc is ideal for metallic, heavy coatings but can present ergonomic challenges for operators.


Thermach systems are specially designed to help lower operator fatigue and significantly reduce maintenance costs. Our AT-400 system uses the “push” method which generates a larger driving force. Thermach's robust wire drive motor is located within the control console instead of the torch. Our lightweight AT-400 torch with quick change wire guides delivers ergonomic benefits unavailable with any other system.


How Electric Arc Spray Works

Electric Arc, commonly referred to as twin wire arc spray, is one of the most productive and economical thermal spray processes. The coating material, in wire form, is fed via a wire feeder into a torch head and electrically charged, one positive and the other negative. The wires are then forced together and create an electric arc, melting the wire.


The molten material is then atomized and propelled towards the prepared substrate as compressed air passes out the air cap. The tiny molten droplets then hit the desired substrate and flatten out and make splats. These splats interlock with each other to create extremely strong mechanical bonds.
