Plasma cutting air compressor selection is important

The plasma cutting used in the market will choose different working gases according to the different cutting materials, of which the most widely used is air plasma cutting.Here you need to use plasma cutting supporting air compressor to assist the use of plasma cutting machine, then about the choice of air compressor we need to know what?

CNC plasma cutting machine in the cutting speed and cutting range than the flame cutting has improved, coupled with the maturity of plasma cutting technology since 2010 to 2012.There are more and more users in the market choose plasma cutting method, compared with the traditional cutting method, plasma cutting with high efficiency, high precision and high stability and other advantages, especially suitable for mass production processing and high-precision cutting requirements, in addition from the cost point of view, as a result of the removal of the cost of cutting gas, the plasma cutting relative cost is more economical, especially when applied to high-volume processing production.Especially when applied to mass production, its processing cost control will be more obvious.

CNC plasma cutting machine adopts air as working gas, what are the requirements for air pressure?How should it be matched correctly?

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, at this time, the plasma arc will be weakened by the speed of injection, and then can not form a high-energy, high-speed plasma arc, resulting in poor quality of the kerf, cut impervious to the kerf accumulation of tumours of the phenomenon.

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.
