9 CUTTING SPECIFICATIONS
In plasma cutting, the thickness of the material to be cut, the speed of cutting and the current supplied by the generator have
values which are related to each other; these depend on the type and quality of the material, type of torch as well as the type and
condition of the electrode and nozzle, distance between nozzle and piece, pressure and impurity of the compressed air, cut quality
required, temperature of the piece to be cut, etc.
In the diagrams we can see that the thickness to be cut is inversely proportional to the cutting speed, and that both these values
can be increased with an increase in current.
