Subject: Pure CO2 for shielding gas?

My lincoln lists straight CO2 as a shielding gas for steel (if memory
servers me right).  Is this OK?  What else can I weld with pure CO2 for
shielding?

Thanks

But they don't serve beer with argon gas   8-)

(I don't know if you do this in the US, but standard practice for
domestic mig welders in the uK is to scrounge half-empty CO2 cylinders
