What are the air requirements for plasma cutting machines
Jul 11,2025
Plasma cutting machine, also known as plasma arc cutting machine, is a mechanical tool that uses plasma cutting technology to process metal materials. It is a machining method that uses the heat of a high-temperature plasma arc to partially melt (and evaporate) the metal at the cutting edge of a workpiece, and uses the momentum of high-speed plasma to remove the molten metal to form a cutting edge. The characteristics are: dual mode selection of fully automatic and semi-automatic cutting; Digital precise control of cutting length; Easy to operate.
Plasma cutting machines generally require compressed air for air requirements. During the normal cutting process of the cutting machine, the pressure and stable gas flow rate, as well as the dryness and purity of the gas, directly affect the quality of the CNC plasma cutting machine's cutting and whether it can start the arc normally. *A good solution is to add a large oil-water separator behind the installed gas storage tank. Before starting up every morning, open the oil-water separator and let the stored oil and water out. The plasma cutting machine ensures that the gas entering the CNC plasma cutting machine is dry and pure.
