Freeze dryer: there is large water in natural air, these water will cause short circuit and huge damage to the plasma power when arcing, the air used for plasma cutting should carry out cold and dry processing after freeze-drying machine, to remove most of the water. It can effectively protect plasma power, increase the protection wearing parts, the life and can improve cutting quality.
Oil-water separator: Because the environment CNC cutting machine in is harsh, there is often a lot of oil molecules in the air, If you do not dispose the oil molecules by the oil-water separator, it will cause the oil molecules gathered in the long run, damage the plasma power, at the same time the oil-water separator can further separate moisture in the air to further purify the air component.
Precautions: For air compressor, we should adjust the pressure threshold according to the actual situation of the plasma power, neither too high nor too low, and this is the key to protect the normal cutting. For the freeze-drying machine, we need to carry out maintenance, often discharge the water to avoid water accumulation. Oil-water separator filter should be replaced and cleaned on time, to ensure the separation performance. Overall, if cutting machines uses cheap air for arc cutting, it must be equipped with the appropriate processing equipment to carry out corresponding to the air. For the problems increased cost of equipment, customers will not care about, after all, compared to the stability and security of the cutting, these inputs are worth. In addition, these devices generally have a longer life, so customers can be assured.
