CNC plasma cutting machine in the use of air as the working gas, what are the requirements for air pressure

In general, when the working air pressure is lower than the required air pressure value of the equipment, the air compressor input air flow is less than the specified value, the plasma arc will be weakened at this time, and then can not form a high-energy, high-speed plasma arc, resulting in poor quality of the incision, the cut does not penetrate the incision of the phenomenon of accumulation of tumours.

From the air compressor point of view to analyse the reasons for insufficient air pressure is mainly due to insufficient input air, in addition to the piston may be cutting machine air regulator valve pressure is too low, solenoid valve oil, air circuit is not smooth and so on.Suggest that users know exactly their own processing requirements, including cutting materials, cutting thickness and cutting time, through the above factors to purchase a suitable air compressor, when the air compressor can not meet the cutting requirements, we can obviously see from the air compressor output pressure display; in addition, we should also check the input air pressure before use, we should check the air filtration and pressure reducing valve adjustment is correct, the gauge pressure display can meet the cuttingrequirements before use.Otherwise, the air filtration valve should be maintained to ensure that the input air is dry and free of oil.
