I've worked in shops where they used straight CO2 for MIG welding steel. It works ok, but takes considerable more flow than AR-CO2 mix. I use AR-CO2 mix in my shop because I like it better, sure it costs more than straight CO2, but it also lasts 3 to 4 times longer than the same size bottle of straight CO2. Therefore making it cheaper in the long run.
