FUNCTIONAL DIAGRAM
CUT-50/CUT50P Air plasma cutting technology.Plasma cutters work by passing an electric arc through air/gas
which is passing through the narrow opening. The gas can be air, nitrogen, argon, oxygen, and etc. The electric
arc elevates the temperature of the gas to the point that make it enters a 4th state of matter. We all are familiar
with the rst three state: solid, liquid, and gas. Scientists call the fouh state plasma. As the metal being cut is
pa of the circuit, the electrical conductivity of the plasma causes the arc to be transferred to the work.
The gas passes through the restricted opening (nozzle) which make it be squeezed at a high speed, like air
passing through a venturi in a carburettor. This high speed gas cuts through the molten metal.
Plasma cutting was invented as the result of ting to develop a better welding process. Many improvements
have made the technology what it is today. Plasma cutters provide the best combination of accuracy and speed,
and the ability of producing a variety of at metal shapes. They can cut much ner and faster than oxyacetylene
torches.
