When I first got into kegging my homebrew, I was quickly disappointed when I learned that most welding shops only swap out tanks of CO2 – they don’t fill them. Well, that sucks because I just bought a brand new aluminum CO2 tank from Amazon. It’s nice and shiny and doesn’t look like I dug it up out of a swamp like an Uruk-hai. I would really prefer to keep my nice looking tank. Anyway, there is a welding shop called Southern Welders in Myrtle Beach that fills CO2 tanks while you wait, and they’re dirt cheap.
They fill my 5 lb. tank every year or so and they can also fill 10 lb. tanks. I’m sure they’ll fill any size you bring them. Here’s their contact info:Southern Welders Supply
