Most common plasma cutters use closer to 7cfm but there is one that only uses 3.2. Normally if you are cutting and run low on air the unit will shut down until it's satisfied again. I have a 60gln and run out of air on a regular basis. Depends on the efficiency of the setup ( torch ). The air dryer is key as well because if your compressor runs solid for 20 minutes it will be spitting water as you cut which degrades consumables in a real hurry. The small units with built in air compressors are handy but I've never met anyone who is happy with them and I sold them for years. Can you imagine the size of the compressor in them? Cut Quick, Cut Short and deal with it I guess.
