Plasma cutting has always been seen as an alternative to the oxy-fuel process. However, the important difference between the two processes is that while the oxygen-fuel process oxidises the metal and the heat from the exothermic reaction melts the metal, the plasma process operates by using the heat from the arc to melt the metal. The ability to melt the metal without oxidation is essential when cutting metals, such as stainless steel, which form high temperatures oxides.
Plasma is an effective means of cutting thin and thick materials alike. Handheld torches can usually cut up to 2 in (48mm) thick steel plate, and more powerful computer-controlled torches can pierce and cut steel up to 12 inches (300mm) thick.
Castolin has developed a complete high quality, Plasma cutting equipment range called AirJet based on the latest technology.
