Laser cutting is the most modern method of thermal separation of material. It is very precise and very fast. Enables cutting of different types of steel and non-ferrous metals. The range cutting depends of the laser power source.
Plasma cutting is a process that is used to cut steel and other metals of different thicknesses. 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.
Oxy-fuel cutting, also knowing as oxy cutting is prefered to use in mild steel cutting. Oxy-fuel cutting are processes that use fuel gases and oxygen to weld and cut metals, respectively.
