CNC plasma cutting machine is a mixed gas by high frequency electric arc.Gas may be air, also can be a mixture of hydrogen and argon and nitrogen gas.High frequency arc "decomposition" or some gas ionization, become the basic atomic particles, resulting in a "plasma".Then, jumping into the stainless steel arc workpiece, high pressure gas blow from plasma cutting torch burner out, export rate of 800 ~ 1000 meters per second (about 3 Mach).This, in combination with plasma in various gas it emits high-energy returned to normal when the high temperature of 2700 ℃.The temperature is almost twice the stainless steel melting point.Making stainless steel melting fast, molten metal by a jet of high pressure air blown away.Therefore, the need to use smoke and slag equipment.
