Mix your own gas.
I found that 90% argon to 10% CO2 was ideal for thin sheet metal that you want to look good. C80 was good for general purpose automotive where some rust would be involved. 50/50 was good for heavier steel that you want to look nice. Normally I just use straight CO2 for anything thicker than 2mm average.
