Being a cheap so and so myself I don't use 75/25 for mig welding except for SS. 75/25 costs alot more and I've not justifyably seen superior results with it. Now the huge bottles of co2 must weigh over 200lbs full which for me is a pain in the keester so I use these little aluminum bottles.....In the past I've paid $15-$18 to get one filled and as much as $35 at welding supply stores (never went back there again) but now I pay $7. How? ''Grow Stores'' that sell medical MJ supplies have these little tanks as well and they fill em cheap....... [Image Can Not Be Found]

I hadn't thought about the little bottles, Bruce. I have one for sparkle water- on tap at the shop.
I haven't filled it in eons but don't they only put like 750 psi in them?

750psi is all you can get from CO2 no matter the size, steel or alu. In other words it's not compressed, it's like propane which is a liquid. Once you go below 750psi it runs out fast cause the liquid is gone. 75/25 is compressed to 2200psi though.
The little bottles last quite a while depending.........
