I don't think the stamping applies anymore other than hydrotest date. Some gas suppliers will sell you any size bottle. Some suppliers will only swap out their own bottles. Like Airgas. It depends on who you deal with
I have had over a dozen different welding supply employees tell me time and time again in 3 different cities that the one single indication of a lease bottle is the company name on the neck ring, or collar.

@@akbychoice yes true but once you go get it refilled you are issued a different bottle correct? One that's already filled and most likely will nvr see that one again lol.
You can do a internet search to find a place around where you live to have your tanks recertified. I have never waited more than a week to have any of my tanks tested and that includes all my scuba tanks. Also if you have a few tanks that need to be tested you can negotiate a better price.
I swap on purchase as a rule to get current hydro dates. Many LWS are casual about the little cylinders so long as they've no arc marks etc. Blank neck rings are common to milsurp cylinders which of course you can exchange when they need hydro but those tend to disappear on the east coast so you may end up with a marked cylinder in return. NONE of the welding supply rules are actual laws and merely reflect over a century of industry consolidation. Another note is you'll still see ancient Linde cylinders marked with swastikas and that is NOT at all related to the Third Reich but was a mark used before WWII because it was a good luck symbol for thousands of years. They are NOT WWII surplus either. Many are stamped with a square to alter the mark. CO2 cylinders besides being useful for MIG welding are great for seating tire beads (get the correct regulator!) and the usual off-road "power tank" uses.
I rented my tanks for a few years before buying them. When I bought them they didn't give me different tanks they would just exchange them when empty so I always had up to date tanks.
@@SteveRivett Not the tank, the neck collar. The collar is not part of the tank. It's peened on under the cap thread. When a gas supplier acquires another company they sometimes have hydrotesters remove the collar and put a new one on with a galiso neck collar tool. They can also have what is known as a slip collar put on, it goes over the existing collar. Or they have the collar grinded smooth and the new company name engraved on it.
3600 PSI is nuts. I watched a half full oxygen bottle fall over in a shop. It knocked it’s valve off on a welding table. Had no regulator. It took off, blew threw a steel wall.

I found a argon bottle. Thought it was a lease. Took it in. They told me it was mine and swapped it.
Leased bottles found in the dump or abandoned are often stolen and the company is usually glad to get them back so they a accept them as trade in. Here in the U.S., it's almost impossible to get your owned bottles back unless you are dealing with a local company in a small market and they will refill and rerurn it...not usually same day so it's best to have back-up bottles until refilled is available. This is usually due to refilling being scheduled based on number on hand and number needed.
you mentioned picking up bottles out of the dump and trading 2 smaller ones for 1 bigger one at the welding supply if I understood, then who owns the 1 large bottle? it still belongs to welding gas supply co and you have to lease it??
Hi I was wondering if you could please help me determine which of the two my cylinders are ? I picked them up from a friend but I’m not to familiar with these tanks. Any help would be surely appreciate it. Thank you.
Thanks for the video. I got 4 300CF Oxi tanks and the stores in my area are such a PITA that they didn’t wanna trade for a single 125CF argon bottle. Only exchange for more oxi. I had to sell them and was forced to buy a tank from them. What a bummer.
I bought brand new harbour freight small bottle's . When I went to get them filled up they traded them in for there used bottles and I notice there's were a little smaller than mine. I was kinda mad that they kept my bottles but he said it was the RULES for there company to trade them in. So I don't know if they are my bottle's I just trade them in every time I get them filled?
yes, that is common for small bottles. You should still be able to take them to tractor supply or anywhere else still. This is sort of good in that you don't need to worry about expiration.
I would like to find a way to locate stolem bottles even though I told the local gas supplier they were stolen they still want to charge rent or me pay for them, I thought they should have insurance for such occurances.But this is my first time down this road having something leased that gets stolen
Our dump is fairly self service with an attendant at the entrance recording what you are dropping off. They have general areas for leaves, steel, waste oil, and propane tanks. I always check the propane tank area as it tends to have these gas bottles mixed in with them. The tanks just happen to be next to the waste oil so I always bring waste oil with me so that I can get a reason to go over to that section.

I am not sure what LSC stands for but the tank is out of date and won't be filled without a retest. You could call a local gas company to see if they know what LSC stands for. You can probably sell the cap for 5 or 10 dollars. If you put it on Craigs List somebody may buy it even if it is a lease because they may have a lease account and be able to exchange it.
They only sell the extinguishers as kits with the bottle, they do not lease bottles with the purchase of the extinguisher. They would probably provide a letter to show the refiller if necessary.
The quickest way to tell who owns a bottle. If the manufacturing date is near 100 years old, it looks like it's been through 2 world wars, and the last retest date is 30 or more years ago, It's a company bottle and will be in the corporate rental/lease service forever. If it's manufacture date is less than 5 years old, looks to be in mint condition and has no retest date. It's privately owned, always expired and thus unfillable and somehow untestable you will need to buy a new one instead.
Good morning, I bought 4 big gas cylinders from someone off of Craigslist. After educating myself about rentals and customer owned bottles, it's obvious all 4 cylinders are rentals. Do I have any recourse? Do you think it was illegal for the guy to sell them? Illegal for me to buy them? This occurred a while ago, and I know I'm outta luck, just trying to figure out what to do with them... Thanks
At the point he sold them it is THEFT and you just bought stollen goods, the company that owns the bottles could get both of you in some serious trouble if they want to, they also could send the cops to recover the stolen goods and you are just shit outa luck if you can't prove who you got them from.
I've been given large Airgas neck ring cylinders by my local Airgas because they lost my blank neck ring government cylinders. I've never heard of anyone (I've welded since the late 1970s) get popped for having large cylinders. They are not like cars with VINs, they're just a way to vendor lock certain size cylinders. If you buy gas from that company they don't lose anything. If you don't have a welder bro with an account who can swap them for you, you could lease one then exchange all four on that lease which is no different to the company than swapping one cylinder four times. Just exchange them one at a time. This is very much a case of "no one who matters gives a shit" despite what spergies sperg about. They are not serially controlled. Alternate option is high pressure cylinders make great bowling ball mortars. I had two empty helium cylinders that failed a visual inspection (ancient Lindes) so I dumped the residual helium then bandsawed them to size and gave them to my blackpowder bro. See bowling ball mortar videos for how to.
If you got them for a song you are still probably ok. I know my local will happily give you a free exchange on one of your owned bottles for bringing in a missing rental bottle which is probably a win win. Some incentive to not turn it into yard art and they get a fairly expensive bottle back cheap.
Just go to your local welding supply and give them back. You might be out a few bucks but think of it as the price you paid for a real good lesson in the school of hard knocks.
Not sure I understand. I buy a brand new (say150 bottle) expensive. Use it once, go to welding supply where they trade it out for a full one and I never see mine again. 🤔🤪🥴
Same here! Mine was an htp, a nice orange bottle 55, and they gave me another brown bottle...are they gonna take it from me? Or charge me extra if I refill it somewhere else???✌
@@JackHudlerI ment to sent that to another comment. You are on point! Exchange is the way to go! I have cylinders over the past year that date back to 1948 still in use.
What you are buying is the right to swap cylinders for a full one and pay only for the gas. Think of it as a kind of license and not as an actual cylinder. I have seen cylinders that say CUSTOMER OWNED on the neck ring. If I had one of those I'd take it to a place where I can get it refilled and get my own cylinder back. In Seattle that business is called Fire King.
With the large tank that you own I'm assuming what you do is take it in and actually have it refilled. Is that correct? Do any of the gas companies actually do an exchange on the large tanks if you own them or is having them refilled the only option?
it depends, on TSC they only swap bottles and they only do small ones. Bigger locations will refill bottles with a good certification on the spot except for acetylene which needs to go somewhere to get refilled. If you own a big tank you can expect to have to recertify it and get it refilled as they probably won't have another customer owned bottle to give you.
No, you wouldn't want to do that as acetylene tanks are filled with acetone and a porous filler to keep things safe. You can buy MAP gas which is in small propane bottles and burns a bit hotter than propane. You can also get MC tanks of acetylene which is about the same size as a propane bottle. A B tank is the next size, B & MC tanks are popular with plumbers and can be used without oxygen for soldering.
@@SteveRivett I learned this years ago in welding class of what MC and B stand for on acetylene tanks. MC stands for motor cycle and B stands for Bus as they used acetylene for running the headlights!!
The plus means 5 years. The star is an additional 5 years. So a plus star equals 10 years. Abd because one is out of date doesn’t mean it’s no good. They can still be exchanged. Abd when exchanging, you can trade an argon for an acetylene or an oxygen for helium. Any tank is exchangeable for another type of gas.
I have been in the industry for 25 years. You are incorrect. The + means they can fill it +10%. The Star means it is good to fill for 10 years. Most of the big gas companies have the exemption to + and or * a cylinder. The small players do not have the exemption to do this.
@@adrewdog that’s good info. I think there is a lot of misinformed people that spread so called knowledge about that plus. I have been good that my multiple people over the years. I’m not saying uoyr incorrect because it makñes more sense than what I’ve always. been told. I always wondered why in the hell such a formula was used and now I see why. It wasn’t. lol good info brother.
Then you own it. Surplus tanks are common. I have several ex-USN cylinders. Best place to ask welding questions is the Weldingweb forum. TH-cam is for videos but no depth.
my understanding is that people use nitrogen because it is usually drier than air. That makes it more consistent. I have a valve body for filling tires with the CO2 bottle when off-roading but I have not used it yet. That could create more heat in the tires as it is heavier than air.
The amount of misunderstanding / misinformation here is astounding. Sad. e.g. showing a tank with a company's inventory sticker on it and saying it is yours is just wishful thinking.
When National Welders refilled my customer owned blank neck ring ex-government surplus tanks they got Airgas stickers (and fresh paint) like everything else they hydro. Never be too sure regarding cylinders as each franchise has plenty of freedom. I've been given marked cylinders in return when they lost a couple of my blank neck ring cylinders. Many LWS don't really care since cylinders exist to sell gas and can be in service nearly a century (like the pre-WWII Linde cylinders with their old good luck swastika stamping) lasting through decades of welding industry consolidation.
It's actually quite easy. I don't overthink it and have bought used to exchange for decades. I get used cylinders easily just by knowing which older brands either of my local welding supply outfits will fill or exchange. Bonus, they often sell so cheap they go for less than the gas, like the three B tanks I bought at auction two of which were full... for thirty bucks. Having oxygen, acetylene, nitrogen (I do my own truck AC work), MIG mix, argon and CO2 cylinders in quantity is insanely handy. So was stocking up before prices went nuts.
Depends on your welding supplier and cylinder size. Most "owner size" cylinders are exchanged without problem in most of the US but it pays to know who does and does not. If you have an old independent shop who fills onsite that's great, but for example most Airgas only fill theirs and the companies they bought from (and blank neck ring owner cylinders in any size, I bought several as government surplus.
The TW stamp stands for tare weight; what the bottle should weigh when completely empty.
I don't think the stamping applies anymore other than hydrotest date. Some gas suppliers will sell you any size bottle. Some suppliers will only swap out their own bottles. Like Airgas. It depends on who you deal with

When National Welders refilled my customer owned blank neck ring ex-government surplus tanks they got Airgas stickers (and fresh paint) like everything else they hydro. Never be too sure regarding cylinders as each franchise has plenty of freedom. I've been given marked cylinders in return when they lost a couple of my blank neck ring cylinders. Many LWS don't really care since cylinders exist to sell gas and can be in service nearly a century (like the pre-WWII Linde cylinders with their old good luck swastika stamping) lasting through decades of welding industry consolidation.
Comment......sounds like all this is more trouble than it's worth.....I think I will just buy new for what I need.
It's actually quite easy. I don't overthink it and have bought used to exchange for decades. I get used cylinders easily just by knowing which older brands either of my local welding supply outfits will fill or exchange. Bonus, they often sell so cheap they go for less than the gas, like the three B tanks I bought at auction two of which were full... for thirty bucks. Having oxygen, acetylene, nitrogen (I do my own truck AC work), MIG mix, argon and CO2 cylinders in quantity is insanely handy. So was stocking up before prices went nuts.
Your talking abunch of bullshit man we aint worried about done of that bs in arkansas
Depends on your welding supplier and cylinder size. Most "owner size" cylinders are exchanged without problem in most of the US but it pays to know who does and does not.
If you have an old independent shop who fills onsite that's great, but for example most Airgas only fill theirs and the companies they bought from (and blank neck ring owner cylinders in any size, I bought several as government surplus.
