cylinder info

[batcon]

I just returned from a trip to phoenix where I ran across a guy who was selling a miller 210 welder. I ended up buying it because he threw in a box of new clamps, a new spool of wire, and 2 large alum. cylinders full of gas and a reg. The problem is I forgot to ask (just assumed) if the tanks are cust. owned. I'm pretty sure they are. Besides calling the guy, is there another way of finding out? Besides getting them confiscated when taken in? I think he bought them because they are alum. and he was telling me they are expensive to buy now.

Contact you local welding/gas supplier and ask questions about their policy before you take the cylinders in.

Take a look at the ring around the valve cap and see if there is a name stamped or cast in to the ring. If there is no marking, the gas company won't be concerned about who owns them. They will be concerned about the hydro date stamp if it is out of date, but they will just charge you for the hydro test. I have never seen an aluminum welding gas cylinder, but that doesn't mean that they don't make them.

This is the first time I've seen them. They are light and easy to handle. I'll see if I can find a name or date on them. They do look good and heavy duty. I just tried the welder and it welds great.

There isn't always a name stamped and that being the case what you might try is calling a couple local suppliers IE Airgas, etc and give them the ol' "I'm looking to buy these cylinders and want to make sure they aren't stolen" story. Then give them all the info that is stamped/cast in the ring area that Pin_Head mentioned and ask them what it all means. Odds are even if it isn't their tank they would be able to tell you who it does belong to, if in fact in belongs to a supplier and not the individual you got them from.

And of course, post back what you find out from them.

I called airgas and he thought that just by the size they were probably cust. owned. Also by the plastic handle around the valve and no collar or ring at the top. I may need to get them hydro tested and he told me to " stay in control" and get it done by a local fire ext. co. They will do it in house and not lose the tanks. About $35 for the test.

Sounds like you got a aluminum co2 tank.

The ubiquitous DOT 3AL cylinder is used for more than just CO2, many manufacturers also manufacture them in 2015 and 2216psi service pressure models for usuage with N2/Ar/He/O2 etc.

It is true that some AirGas company owned cylinders aren't marked, but they could probably tell them from their serial number. My own cylinder I have at home looks the exactly same and has an AirGas sticker because I bought it from them. I'm not sure that your local welding supplier would know who they belonged to or if they would care. AirGas has the contract to supply all our gasses at work and of the 12 cylinders I have, only 6 have AirGas cast into the ring. The others have a bunch of strange names of companies that probably went out of business over the last 80 years. One cylinder has hydro dates back to 1917. We don't use any puny cylinders, so that is why I haven't seen an aluminum one.

These are not small, probably around 38'' tall' but not the pro tanks. And that is why the guy thought they were prob. cust owned. Now they do have a sticker on them, with the name of a welding supply house. I'm thinking maybe those were put on at a time they were filled or sold, I dont know. I have my torch tanks that I bought used from a guy, but they came with a certificate of ownership.

When I take my customer owned tanks down to the local metal/weld supply place to be filled, they just roll my old one out back and give me a new one. I don't think I've ever had a tank filled. They do tell me to keep the paper trail for the last couple of "fills" to show that I own the rights to a tank.

Just saying...

I've done that with my other steel tanks, but I want to keep these since they're aluminum. Much easier to handle.
