Newbie - Clusters and lower / irregular heartbeat? in General Board Posted August 28, 2018 Ah, bummer! I may as well buy a industrial tank then huh, would be cheaper in the long (short) run. I had decent sized bottles on my MIG and for my torch and last time I had them filled was only like 11 bucks for the O2, and a medium size tank will be easier to lug around. $175 seems like a great deal for that size. I see a few on Craigslist and they are about. The same price for smaller tanks, but most guys aren't separating them from the acetylene tanks. You rock man, thanks for the quick research!
