17 years ago
cylinder exchange cabinent (similar to propane) in front of Home Depot
in Irving, Texas (near Fry's electronics). Instead of propane, it had
argon,co2,nitrogen,acetlyene,oxygen, and trimix. I didn't see the
prices, but it looks like they have everything from a 15 cuf to 80 cuf.
Any other Home Depot's have this?
