Cutting with nitrogen instead of air

Most MetalWise units from 130A up can use 99.995% pure nitrogen as the plasma gas, for a straighter and smoother cut.

Which units

The P-METALWISE/125, P-METALWISE/165, P-METALWISE/200 and P-METALWISE/260 list nitrogen at 99.995% purity as an option.

When it pays

Nitrogen costs more to run than compressed air, so shops tend to use it for parts where the edge finish matters, and air for everyday cutting.
