For super dense, low porosity coatings. Unlike regular arc spray systems that use compressed air, the HVAF Arc 300 utilizes a high-velocity, high-temperature jet (through combustion of air-propane mixture) for atomization. This not only provides superfine particle atomization, but also creates a reducing oxygen-free environment that envelopes particles in flight, shielding them from oxidation. This effect, combined with very high jet velocity, permits the formation of very dense, low-porosity coatings. This is the only system in the world capable of producing such coatings from wire stock.

Uses:
The Arc Master 300 spray system's compressed air requirements are 50 SCFM at 125 PSI. The max operating current is 300 Amps. The spray system ships with a Miller power supply (450 A, 18-38 V, 174 kg weight).
In addition to compressed air, the system requires a fuel gas such as propane, propylene, natural gas, or MAPP-gas. Most commonly propane cylinders are used.
For application of materials with low melting points the spray gun can be ordered in a High Feed Rate (HFR) configuration. The following table shows the spray rates of some common materials.
