CO2 is about half the cost of argon. If you are only welding mild steel, CO2 will work. Welding stainless steel or aluminum would require argon, but with a simple MIG welder, a small 20 pound tank of CO2 would be fine. The tank can be purchased for about $125 here locally, and about 30 bucks to fill it.

could you use a propane tank? and could you fill a bowl with CO2, then weld down in it to avoid having to flow gas?

Oh, damn...Not sure about the bowl idea...but nobody will fill a propane tank with CO2 for you.

What about welding inside a sand blast cabinet with a fire extinguisher connected? The CO2 wouldn't blow away in there.

ok thanks, I'm definitely going to look around and see if i can get a used tank and maybe a whole setup used
