Plasma cutters require an air compressor to function (unless your machine has one built in). You'll need continuous air pressure to make cuts. If you have a small compressor you may have to wait in between cuts for your compressor to refill.
In respect to this, what kind of gas do you use with a plasma cutter?
Argon gas
Accordingly, what does a plasma cutter run on?
Plasma cutters work by sending an electric arc through a gas that is passing through a constricted opening. The gas can be shop air, nitrogen, argon, oxygen.
All plasma manufacturers include minimum air flow and pressure requirements in the owner's manual. If you do a lot of cutting, or plan to cut thick plate, we recommend using a compressor that is 1.5 to 2 times the plasma system requirement.
