- Plasma cutting is a process that is used to cut steel with different thicknesses (thicker steel material which cannot processed by laser cutting) using a plasma torch.
- In this process, an inert gas (in some units, compressed air) is blown at high speed out of a nozzle; at the same time an electrical arc is formed through that gas from the nozzle to the surface being cut, turning some of that gas to plasma.
- The plasma is sufficiently hot to melt the metal being cut and moves sufficiently fast to blow molten metal away from the cut.
