[TheForge] dry liquid nitrogen vs air compressor & liquid oxygen vs oxygen cylinders

[terry l. ridder]

hello;

would anyone know of an online economic comparison of dry liquid
nitrogen dewar verses an air compressor?

the primary reason for having an air compressor would be to provide air
for a plasma cutter. a dry liquid nitrogen dewar supplying the required
amount to 'air' would seem to alleviate several of the problems of using
an air compressor. i.e. humidity, cycling of the air compressor, size of
the air compressor and reservoir, blowing down the air filters, etc.

also an economic comparison of liquid oxygen dewar verses compressed
oxygen cylinders for cutting and welding would also be beneficial.
