High Density Arc Spray Coating System

allows a continuous and precise pressure on the wires at all times and does not change when new wires are loaded. More importantly, the spring pressure adjustment is set to the correct amount, not relying on operator experience.

is a Thermion exclusive feature that minimizes friction and drag on the wires as they enter the feeder. This is such an important performance upgrade that all Thermion's arc spray systems include this feature.

are also one of the important performance features that are included in all Thermion's arc spray systems. Most arc spray wires are packaged on spools and during the packaging process the wire develops a helix, spiral, or kinks; these features can cause spraying malfunctions. Thermion removes the malfunction potential by using wire straighteners, which are built to straighten solid or cored wires using the same unit so operators can switch wires without changing straightener parts.

is another Thermion exclusive feature available on the High-Density spray system. The six-roll system adds performance value in providing an absolute non-slip wire feed at all times during operation while overcoming friction on the wires caused by dryness, dust, or wire defects.

is a feature of the six-roll drive and worth mentioning as a separate performance improvement item. On the last set of feed rolls, just before the wire enters the liners a smooth set of feed rolls iron the sires to knock down the knurls put on the wires by the four other feed rolls. Knurled feed rolls are necessary to provide a positive feed; however, they add friction and wear to liners and tips. The wire ironing feature knocks down these knurls, reducing friction and extending the life of liners and tips, therefore, enhancing spray performance.

improves current flow and reduces voltage loss. Thermion has minimized the number of electrical connections while maintaining a portable, quick set-up spray system. History has shown that poor lead connections can cause the equipment to malfunction in many different ways that are often hard to diagnose; thus, minimizing connections reduces problem potential.
