Ironken trading the CO2 tank for an AR. tank is a no go, but I'm still thinking, and hope you and others " in the know" will keep me on the straight and narrow. How about if I swap the 75/25 tank for an Argon tank, keep 2 tanks---The CO2 for the majority of mig welding steel, and the Argon tank to use for spool gun aluminum, and when I have thin sheetmetal to weld. Assuming straight Argon is OK on thin steel. By now you must be thinking that I am an extreme cheapskate, and your probably right but it's more because I'm trying to add the ability to weld aluminum, bearing in mind that I may sometimes go 6 months or more without welding anything at all, which is why I avoiding buying a full Tig machine.
In the post above the only problem you cited about using CO2 with mig welding is burning holes in thin metal. Please anyone If you have others issues with using CO2, let me know before I do this ! Thanks for your time, JR49
Pure Ar is a no go on carbon steel. I have never tried it but, understand that Co2 stops sputtering and stabilizes the arc. I think weld.com has a vid on this very subject on Yootoob.
I don't think you are cheap....just making the most of what you got. I was too cheap to buy an extra cylinder of pure Ar for back purging so I bought a Smith dual flowmeter. I get it.
