Plasma cutting is a process that utilizes a highly positioned nozzle orifice to constrict a very high temperature, ionized gas so that it can be used to melt and sever sections of electrically conductive metals.
Plasma cutting is a process that greatly improves the edge quality and squareness on materials thinner than 3/8" (10mm). Plasma engineers have known for years that to improve cut quality on thin materials it would be necessary to increase the energy density of a plasma arc to the range of 40,000 to 60,000 amps per square inch. This is a major increase over the conventional energy density of 12,000 to 20,000 amps per square inch.
Recent breakthroughs in conventional oxygen and nitrogen plasma cutting technology have enabled the development of plasma systems that produce dramatic cutting improvements over previous systems on thin materials.
