Plasma cutting equipment with compressor is one of the variations of the plasma cutting equipment set. In that architecture the supply of gas for the formation of plasma stream is forced by the compressor. The supply of gas can be also from a cylinder or main line, but this approach does not give high performance and stability, especially in the situation with cylinders, because the gas flow is very high.
Most often the system uses the air, however, nitrogen, oxygen mixtures, and other gases can be used as well. The usual solution is a compressor delivering air under high pressure.
Power source can be either inverter or transformer type. The latter option is much larger in size and weight, significantly worse in energy efficiency and arc quality, therefore such plasma sources are gradually leaving the market, despite their high reliability.
