Now the plasma arc cutting machine mostly by gas pressure to control the flow of CNC laser cutting machine, because when the gun is constant aperture control gas pressure will control the traffic. Cutting a certain thickness of the material gas pressure to be used is generally choose metal CNC cutting machine, while if other special applications, the gas pressure needs to be determined by the actual cutting test device in accordance with the data provided by the manufacturer. Therefore, to achieve good cutting quality, which requires not only technical personnel according to the normal operation of the process, but also the need for technical staff have full experience cutting adjustment! Plasma cutting machine developed to 2012 CNC cutting machine, the working gas can be used (working gas is a plasma arc conductive medium, but also bring hot body, but also to rule out cuts in the molten metal) cutting characteristics of the plasma arc and cutting quality, speed has a significant impact. Commonly used plasma arc working with an argon gas, hydrogen, nitrogen, oxygen, air, water vapor and some mixed gas.
