I'm having trouble getting 02 tanks. I can't get in to my doc until probably February, and I'm almost certain that I'm going in to another cycle now. I've got my clustermasx and RJ (Mr. Happy's) regulator. I tried a friend of ours who is a welder, but he can't help me, probably due to legal stuff, but I'm not going to press him. I'm looking on e-bay and finding lots of welders tanks, but can't tell from the descriptions exactly what size they are. And if I were to get one, how do I get it filled?
Anyone have any suggestions???
Need your help.
Thanks
Sandy

#2 tank is equivalent to an H tank. 7,000+ liters/250+ ft3, 130#
#4 tank is equivalent to an MM tank. 3,500 liters/125 ft3 75#
#7 tank is close to an E tank with 550 liters/20 ft3 20#
The #2 or H tank is a pisscutter to handle.....heavy when loaded.
The #4 or MM tank is still heavy at 75#, but manageable.
No matter what welding O2 tank you get, it will (or SHOULD) have a 540 adaptor. The size of the tank isn't as important as the immediate availability of refills. Ya just don't wanna run out on a Saturday afternoon. Scratch that. Ya just don't wanna run out.

It is up to YOU to educate yourself and then help your doctor plan your treatment. If you just sit down in front of your doctor and say "make me better" you are setting yourself up for a great deal of pain.

Have you called and asked them to order it for you in the mean time? If you were near me, I'd give you one of mine! I just got my O2 for the first time and they sent me out the door with the max that my HMO will cover for a month, so I have 6 E tanks!

Here's an idea,
Go to your nearest welding gas supplier (they should be in your yellow pages under "welding equip & supplies" Tell them you are transporting live fish and need a "80 cubic foot oxygen cylinder." DO NOT suggest in any way that you are going to use this oxygen for your headache(s) or that you are going to be breathing the O2 via a mask. (I learned this the hard way. They can be very stubborn. Blame the lawyers.)
The 80 cubic foot cylinder is 36 inches tall (including the valve) and 22 inches in circumference. Full, it weighs about 50 lbs (thats a guess). At 2200 psi, the usual "full" pressure, this thng has a little less than 2,300 liters of O2. Of course you don't want to let the cylnder pressure go all the way down to zero. About 100 psi should be considered "empty" so you won't really get 220 minutes (three and an half hours at 10 liters per minute) out of a cylinder this size, but close enough for government work.
I bought an 80 cuft tank in November for $125. The oxygen in it cost $9. Last week, when I went for a "refill" (actually they just roll out another full tank for you) it cost me $11.00. This was in South Georgia.
When I got my cylinder "refilled," the retailer asked me, "You want to buy another bottle? I've got one here that a guy wants to sell for $80." I bought it. I've got a verbal promise that they will sell my tanks for me any time I'd decide I don't need them anymore. They think I'm transporting live fish.
You can rent/lease the tank (a.k.a. cylinder or bottle) by the year - but I figured I'd come out better buying than renting.
A couple of safety tips:
- always open and then close the valve on the oxygen cylnder a liittle bit BEFORE you attach the regulator. This blows out any dirt and such that may have gotten into the connector. Even the welders do this - it protects the regulator.
- always move the cylinder with the cap screwed down around the valve (when you see the cylinder - this will be very evident) If the cylnder falls over and knocks the valve off - it's happened! - the cylinder becomes a rocket! Actually! It could blast it's way though a wooden wall! Could ruin you day.
- After your regulator is attached, open the valve on the tank just a little bit (enough to hear the gas flowing) then after a moment you can continue opening the valve. It's not necessary to turn the valve all the way open. You can tell when the oxygen is flowing at a good rate. Opening the valve slowly step-wise reduces the possibility of damaging your regulator with a sudden drastic increase in pressure.
- Use your O2 cylinder with it standing up on end. Secure the cylinder to something substanial so that it won't accidently fall or get knocked over. The cylinder is supposed to be "safer" standing up than lying down. Migiht have to do with water/condensation in the tank. There's not supposed to have any - but you never know.
All this stuff about protecting the regulator is really about protecting YOU. You can get another regulator (eBay or Randy) but a busted/damaged regulator can BAD news for the person with his/her face at the other end of the tube.
What the cylinders are called is somewhat confusing. Most experienced welders get their cylinders by volume, 80 cubic foot, 124 cubic foot and so forth. The cylinders that you'll see mostly mentioned here are medical oxygen and go by letter designations (e, m, k and so forth). it's probably different in the UK - everything else is. Anyway, you are buying welding oxygen so make the supplier think you know what you doing, and ask for a "80 cubic foot oxygen cylinder." That'll make you sound like a pro.
I know this may sound complicated and a little intimidating. But after you've done it once or twice - it's a piece of cake. And then YOU will be the expert!

THANK YOU Squanto! This goes in my file for future need-which I know I will. (Right next to all the great stuff from Mr Happy and in sight of my clustermasx from Ben- a prized possesion.)

Another option.
Oxygen tanks can often be picked up at your better local auto parts store, like NAPA, as well.
They may be on scheduled deliveries from the gas wholesalers. Who run to auto parts stores as well as medical suppliers.
Just say you were told to pick up a smaller one up by someone, (for a cutting torch) and plead ignorance. They will want to sell you an acetylene tank as well but you definately dont want that.
Then heed squantos advise.
