The plasma cutting process may be used to cut any conductive material, including carbon steels, stainless steels, aluminum, copper, brass, cast metals, and exotic alloys.
In this process, a specialized nozzle design narrows the arc and increases energy density. Because of the higher arc energy, high-definition plasma achieves superior cut quality on materials up to 50 mm (2”) with superior cut edge angularity, narrower kerf, and higher cut speeds than conventional plasma cutting technology. It's not uncommon with these systems to achieve cut part accuracies within the +/- 0.25 mm (0.010") range.
Today’s high-definition systems allow very high levels of automation and are intended for automated applications only. In the most advanced systems, virtually all of the machine operator’s expertise (required to get good cut quality on earlier plasma systems) is essentially captured in the CAM software that manages the day-to-day cutting operations.
With high-definition plasma, cut holes are round and have virtually no taper. Edges are square and dross-free. Cut-to-cut cycle times allow much higher levels of productivity. A single-plasma system can cut material thicknesses from thin gauge to over 182 mm (6”), using the same torch. The torch can cut and mark the plate through the same nozzle orifice.
