Portable CNC Gas Cutting Machine

There are five main types of plasma gases used in CNC plasma cutting systems: compressed air, N2 (nitrogen), O2 (oxygen), H35 (argon-hydrogen), and F5 (hydrogen-nitrogen).CNC means Computer Numerical Control. This means a computer converts the design produced by Computer Aided Design software (CAD), into numbers. The numbers can be considered to be the coordinates of a graph and they control the movement of the cutter.
