              How to choose plasma cutting machine?

              Sources:www.eyewnder.com | PublishDate:2019.03.16

              1. What is plasma cutting technology?
              Plasma cutting is a kind of processing method which uses the heat of high temperature plasma arc to melt (and evaporate) the metal at the cutting edge of workpiece, and eliminates the molten metal by the momentum of high speed plasma to form the cutting edge.
              2. How to compare plasma cutting with flame gas cutting?
              Plasma cutting can only be effective on metals that can be used as conductors - low carbon steel, aluminium and stainless steel are typical examples. When cutting low carbon steel, operators will experience a higher speed and deeper cutting effect.
              Flame gas cutting cuts metal by burning at high temperature or by oxidation. Therefore, its application is limited to ferrous metals such as steel, which can be treated by oxidation technology. Metals such as aluminium and stainless steel form oxide constraints for further oxidation. This makes it impossible for traditional flame gas cutting to deal with this kind of material. Plasma cutting, which is not resistant to oxidation treatment, can effectively cut aluminium, steel, and other conductive metals.
              And different kinds of gases can be used in plasma cutting. At present, most people use compressed air for plasma cutting. Air compressors can be purchased in most cities. Therefore, flammable gases and compressed oxygen are not needed as operating gases in plasma cutting.
