Extreme temperatures make safety the primary consideration for Thermach Plasma coating systems. The ability to run Hydrogen as a secondary gas, a built-in safety purge system, component design, and robust warnings and alarms improve safety while maintaining ease of use.

Electric Arc

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, the driving force is a bigger, more robust wire drive motor 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.


The high temperatures and high velocity present in High-Velocity Oxygen Fuel processes make safety paramount.

Thermach HVOF systems are the perfect mix of safety and performance. Easy-to-use controls, high-impact visual alarms, and a NEMA 12 enclosure provide accurate control over gauge and flow of ceramic and metallic coatings for the optimum corrosion resistance your customers expect.
