8.1 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 as in Fig. 1, 2, 3, 4, 5 we can see that the thick-
ness to be cut is inversely proportional to the cutting speed,
and that both these values can be increased with an increase
in current.
