Gas fill question about Airgas

[firestorm13666]

Today i went to get my Tri-Mix tank swapped for a Oxy on was i would have torchs.Well The tank was the last of two i got in a deal with a old Linde Mig welder at a barn sale over a year ago. They were both 300CF so from my reading here i would have a time getting the filled. Well i got one swapped out for two 150CF C-25's for the price of the fill. Well with the other i went back to the place i took the first in hopes of smooth sailing with this one. But that was a no go i was told to take it to Airgas as it had AGA painted on it. Well i got to Airgas and had to deal with a **** that give me a problem every time i go there. Well he told me tanks this size are not owner size and asked if i had proof of ownership and i told him where i got them. And ask would i be able to trade it for a same size Oxy or the same in CF with smaller ones. Well after that comment he went off on a rant about its not mine and acted like i was a theif.Well he said he would have to ask the Manager about my questions. After this he went in the back and then came out and told the guy that handled the tanks to swap me out for a full one. All said just for the fill it was $30 and the tanks was out of date. Now to my real question :D on the reseat it has the size and then under it in prentices (customer owned cga 540).What does this mean?The one thing i can think of is that i now have proof of owner ship on 300CFer.Thanks

It has been a gentleman's agreement, between most of the welding supply dealers, for years, not to sell that size cylinder, but some one can stamp into the cylinder, anything they want to. If you really want to know get the cylinder serial number and go to the CGA and ask who's cylinder it is. John

You own it and now have paperwork to prove it..... I ran into the same with my 251 cuft oxy....on my receipt it states customer owned 251 oxy....

I said an agreement, not a law or restriction to sell them. John

cga 540 is the designation of the oxygen valve. You now have washed that cyl through the system. Keep that reciept and gaurd it with your life and all will be fine in the future.

I've never had any trouble swapping 330cf cylinders around here. Even if the necks are stamped. I have two that I picked up used. One was free and the other cost me $50.

Thanks guys that was what i wanted to hear:D.Well i guess in the end The deal i got over a year ago for a Linde VI-206 power supply,mig-31 feeder and two 300CF tanks became better then just a working welder.I now have the 300CF oxy and two 150Cf C-25 tanks that i own:D.Now i hope the *** hat at AirGas will be nicer next time u go.

Airgas is the same way here locally, so I avoid them. There are simply too many other supply houses that don't hassle you about tanks, so I don't bother with them. Of course, my largest tank is a 230-250cu.ft oxygen, so I can't speak on anything larger.
