I don't know much about plasma cutters, but I don't think they use all that

I've got a little plasma unit with a built in compressor - not much air 
volume at all, really.  Since air is mostly nitrogen, it's about the 
same thing I imagine.  The oxygen in air probably has an effect, but it 
hasn't given me any trouble.
