AWG, Gases and Welding Supplies, Cincinnati OH

Very professional, courteous, and knowledgeable staff. They went out of their way to trade my nice aluminum tank for one that looked the same. As of June 2015, a 5lb Co2 fill is $20 ($12.50 + $5.50 hazardous material charge + tax). If you have a small tank, you'll find a better price elsewhere (Listermann is $12).

These guys are knowledgeable about all things CO2. Very inexpensive and my guess is they are family run due to their friendliness. I was getting a 5lb. CO2 tank filled and the gentlemen took the time to explain all of my newbie questions and gave me tips on my kegerator.

Watch out for these guys, I drove 40 minutes for a tank, even called in advance. Sold me an empty tank even after being assured it was full (and charged for a full tank). "When you want a refill just pull around back, " I was told. Well, I needed a refill after getting home, you morons!

I needed a small fitting adapter for my oxy- acetylene torch, Bill (Mgr.) Called and found this fitting. This fitting cost under $3.00. You'd think I was ordering a $500 part (all the talking and searching that he did.)
