Plasma cutting with different working gases can cut a variety of oxygen cutting difficult to cut the metal, especially for non-ferrous metals (stainless steel, aluminum, copper, titanium, nickel) cutting effect is better; its main advantage is to cut the thickness of the metal Time, plasma cutting speed, especially in cutting ordinary carbon steel sheet, the speed of oxygen cutting method up to 5 to 6 times the cutting surface smooth, hot deformation is small, almost no heat affected area.
During the development of plasma cutting, the working gas that can be used has a significant effect on the cutting characteristics of the plasma arc and the cutting quality and speed.
