Alright, I've got a 220v mig welder and was wondering if I could use straight CO2 . Alot of the mig spools I've seen have Argon/CO2 or CO2 only listed on them. What are the pros or cons. The reason I'm wondering is I've got a 10lb and a 20lb bottle of CO2 both full so if I don't need to get another cylinder that'd be great.
If I should get Argon/CO2 mix what the hell's the difference in the mixes. Is more argon better or just stick 75/25?
Thanks
