How to get your used Welding Tank for FREE !!! and make extra money $$$

[@barenthoffman2840]

Fabulous Info. You are a generous man for sharing your "hustle" strategy!!! I've already bought and sold several tanks, and well on my way to a set of "Free" tanks for my MIG/TIG welder.

[@PranaTech]

Thank you my brother! It brings me great joy to hear from people like you who can take information and implement it and make some money! I’m a deep believer in karma and what we put out into this world we get back in so many wonderful ways. Thank you for your kind gift through your super thanks donation. Certainly not expected but greatly appreciated. Peace and love to you my friend! 🙏❤️😊

Thanks for the video. Bought 2 helium tanks for $150 total. Swapped one for 75/25. Sold the other for $225. Great side hustle!

[@PranaTech]

Hi Matthew, thank you for the great comment! That’s a great deal! I’m glad to see someone else capitalizing on this largely untapped market. 👍😁Don

[@2XXEquiz]

Wait, I have a question. I am new to welding and I have not buy any tanks yet but can I use a helium tank? I think you answered this question in some way but more specifically I am referring to those used at party rentals.

[@PranaTech]

Yes, as long as it is a large high pressure tank and not the little pink helium tanks that are sold to the public for parties. Just make sure that your local welding supply will exchange a helium tank for a argon or argon/Co2 mix tank before you go buying one. I don’t want you getting stuck with one. 👍😊

Dude! This Didn't cross my mind until I watched your vid yesterday 19May2021. I looked everywhere and as I was realizing "Everyone is On To The Secret" , "As A Last Resort" I checked Fb (I hate Fb and Refuse to even look at crap on there!) found a 300cf "Nitrogen Tank" for $50. Just went and Snatched it up today. Gave $70 since he included the bottle cart! Thank You! Got this to exchange for 100% Argon for myself but will Now be Actively Hunting for these ! Don't worry, I'm in KS so won't be edging in on your territory!

Hi George! Wow, those are great deals! Sorry I didn’t get back to you earlier today, I was gone welding all day. It looks like you can get the valves on Amazon for $22 plus shipping.www.amazon.com/Sherwood-CGA580-Inert-Cylinder-Valve/dp/B01H0G47WS/ref=sr_1_3?crid=HSVCWI62695S&keywords=580+inert+gas+valve&qid=1680394621&sprefix=580+inert+gas+valve%2Caps%2C152&sr=8-3 😁👍

[@KevinK5516]

Great video but a word of warning for others before you go running out and buying tanks is to call your local gas suppliers FIRST to make sure they'll accept exchanging a tank from a different type of gas. I had found two 281 CF oxygen tanks on my local CL for $100 each and was about to pick them up but then called up the gas suppliers first before buying. Everyone I talked to said they would only do an even cylinder swap for a cyclinder with the same gas valve. This is the Bay Area of Northern California. I'm jealous of people living in areas where the gas companies are more chill about the exchanges. My local Airgas store just quoted me ~$800 for a 125 CF bottle of Argon if I did not have a bottle to bring in for exchange!

[@PranaTech]

Hi Kevin! Well that is a real bummer! Here in Tucson, the dealers are so short on tanks that all they care about is the steel. Airgas told me the other day that they are only exchanging tanks now and aren’t selling any more tanks because they only have a supply enough for exchanging. The will order a tank for customers but it will be about A year and a half to get one. They have over 3500 tanks on order right now.☹️

[@ldgillette]

Our local Airgas store overcharges something terrible. I find the local Central Welding Supply reasonable (Fairbanks, Alaska).

[@glasslinger]

Something you didn't mention is leased tanks. A lot of the tanks you find around are property of a company and are NOT abandoned. These tanks will NOT be accepted by a shop to be exchanged or filled unless you have the lease papers. The tanks are usually stolen. Most leased tanks have the name of the lease company stamped on the collar right below the valve. Steer clear of leased tanks since you can be charged with possession of stolen property.

[@PranaTech]

Very good point! Thanks👍😊

[@earthstewardude]

BS! They're not usually stolen - people die and the family members find them in the barn or garage... etc.

[@glasslinger]

@@earthstewardude Not BS at all! I have a neighbor that runs a welding supply store and he gets people all the time trying to get cash for stolen tanks. Some are simply lost tanks but the cops don't distinguish. "But officer, I just found that bag of money on the side of the road! It can't be stolen!"

[@earthstewardude]

That's correct! I get most of my gas tanks from widows. I have come across so many tanks with company names that are long out of business! I have 3 companies here that will exchange with me because they know I'm a straight up guy who finds them from the widows or kids of dead guys.

[@PranaTech]

I have suspected that some of the tanks that I’ve gotten have been from deceased as well. I haven’t asked, but it sure looks that way.

[@BURNETTWEALTHGROUP]

Maaan you’ve just set me up for a goldmine. I don’t how many times I’ve seen these tanks free and never gave it a second thought. Now I’ll never make that mistake any more. Like that at the end of the video you gave a little info on the tank markings that’s very helpful, plus I didn’t know you could put different gases in any tank. I thought they were tank specific that too is an eye opening moment for me. Tank hunting now lol

Thank you! I really appreciate your kind words!🙏😊 I haven’t had any luck with scuba tanks. I have looked at them and there are a lot available here as well. The tanks need to be something that the welding supply uses. They just don’t know what to do with the scuba tanks so I just leave them alone. 👍

[@PranaTech]

Hi Luis! I’m glad you’ve been successful with this! I would not stop just because Praxair asked for a hazmat cert. You only need a Hazmat certification if you are a commercial company. Those laws don’t apply to your average citizen. You are allowed by federal law to transport your tanks and exchange them without any hazmat certification. Don’t let the man keep you down my brother! It is your right to make some extra money this way and they can’t prevent you. 😁👍

[@landandsea333]

My local welding shop said they arent as concerned about a tank needing to be hydro'd but newer DOT requirements specify a tank can't be refilled anymore if the PSI number is under 2000. Does anyone know what to look for on the tank?

[@PranaTech]

Yes, most modern tanks have a DOT stamp on them and the last 4 digits is the test pressure rating for the tank. Most of the tanks I find are 2200-2400psi ratings. Hope this helps!😁👍

[@Max-ye9xg]

Hello good video a tank which is tested and has the date and no plus but only a star, is that five years

[@PranaTech]

Hi Max, if it has a star, it is a 10 year tank. The plus just means it can be overfilled by 10% 😊👍

[@user-fb3td6cl9d]

How about tanks that had liquid petroleum gas LPG that's used for even domestic cooking? Are they high presure tanks good enough?

[@PranaTech]

Hi there. No LPG tanks won’t work. The welding supply houses won’t take them in exchange. Sorry.☹️

[@barenthoffman2840]

Are the Army tanks considered "owned" tanks and are they exchangeable?

[@PranaTech]

Yes, they are decommissioned tanks and are sold out into the public domain to become part of the inventory that is out there. They are some of the highest quality tanks that I have come across. 😊👍

[@nelsonsantos770]

The oxygen bottles, what can you change it for Argon? C25?

I always take a picture and ask the guys at the welding supply if they will exchange it. I’ve been burned a couple times that way. If I get stuck with one, I either grind the name off or cut the tank and make it into a garden bell.😁👍

[@josephbebout8259]

will gas supply company take tank with other company collar marking

[@PranaTech]

Hi Joseph, here in Tucson it is a crapshoot. If the company on the ring is still in business, they won’t take it in trade. I’ve gotten to the point now that I just call them before I purchase the tank and make sure that they will take it in trade. 😊👍

[@provenancemachining]

The problem is fighting with a big gas company to even take that tank for fill-up and not try to get you to take their own on a lease. All I have close in my area is Airgas and nexAIR, and from what I understand, they make it such a pain in the balls to fill up a customer-owned tank (125cu or more) that it almost forces you to rent their tanks just to avoid the hassle. There really aren't any small local welding shops in my area anymore, and if there were, they were bought up by Airgas. Otherwise, this is an awesome way to save on bottles as long as you can verify the DOT stamp and inspection date.

[@PranaTech]

Well that stinks! Here in Tucson the competition is pretty widespread and we have enough smaller companies that they can’t pull that crap. Airgas tries to charge $50 for a tank that is out of hydro test and so they lose a lot of business because of this. The smaller companies only charge $10-$15 dollars when you exchange a tank out of hydro. Airgas definitely has the worst reputation here in town.

[@ldgillette]

I hate AirGas. Fortunately we have two competitors here with better prices.

[@larryschmidt977]

the oxygen and acetylene tanks may be considered the same for purposes of buying and selling empty tanks but they are certainly not the same inside acetylene has acetone and a porous mass inside the cylinder, oxygen tanks have no such stuff, hence you also can't fill an oxygen tank with acetylene or vice versa

[@PranaTech]

Hi Larry! Yes, you are absolutely correct on all points! Acetylene is a low pressure tank and has much thinner steel so I generally stay away from them because most shops will only exchange a high pressure tank for another high pressure tank. At least that is the case here in Tucson. 😊👍

[@barenthoffman2840]

It seems like the 50CF-125CF size tanks sell easier than the larger 200 CF+ tanks? Curious what categories you list them in when you sell... "Tools" or "Business" or "General" ?

[@PranaTech]

Hi there! Yes sometimes the smaller ones do sell faster. It does seem to depend on the types that are looking at the time I list though. The DIY garage guys tend to prefer the smaller tanks and the more serious guys tend to want the larger tanks. I sold two large tanks to a guy a month ago and was wishing I had more. I usually list in tools but it seems most people find them by search terms rather than categories of listing. 😊👍

Is this kind of tank is good enough to use it for welding gas? Should I empty or cleaning the tank first? Thanks in advance.

[@PranaTech]

Good morning Sar! That is great that you got your tank for free! I am going to assume that it is a CO2 tank since you said that they were using it for sodas. If it is CO2 then it will work great for Mig welding just as it is. You will need to get a specific regulator designed for CO2 tanks and welding. There are a lot of CO2 regulators that are made for growing or soda dispensers that don’t have accurate flow meters for welding. Have fun and let me know if you have any other questions. 😊🙏Don

If not or if they are hundreds of miles away from me, I just grind the name off the ring and paint the ring flat black. If they are a local company, I call them and ask if there is a reward for one of their tanks. Sometimes they will give you a refill of your other tank for free to get their tank back.

I sold a couple tanks last week and one of them was to a guy from Mesa who drove down to get it because there is nothing available in the phoenix valley. I called airgas the other day and they said they have 3400+ tanks on order and the wait time is over a year to get one now. So if you see a tank come up for sale, grab it. I’m not very active in the tank game anymore due to the amount of welding work I have right now, so I won’t be competing with you for the used tanks. Mathesons on Grant rd. Just west of Oracle rd. Is the best place to exchange your tanks when you find one. If it is out of test date they only charge $15 where as most of other shops are charging $50 or more. Let me know if you have any other questions and I’m always happy to help. 😁👍Don

Propane tanks work?

[@PranaTech]

Hi there, I believe it will work because they are rated to 300 psi. You would just need to drain it and flush it clean before welding on it so you don’t shorten your lifespan.😊👍

I believe a 20 pound co2 translates to a 60 cubic foot tank. Yes, most shops will trade in two tanks for a larger one, but I would confirm that with your local shop before you start buying the used tanks.😊👍

Hi Edwin! Here in Tucson the answer is yes. They don’t care about the gas,only the steel of the tank. Others have informed me that it is not the same rules in other parts of the country. Best thing to do is call your welding supply places and see if they will exchange it. 😁👍

Learned a lot through this video Sir. I too live in south Tucson so we must be close; may have even crossed paths at the stores? In any case, I'm a recently retired Vet and looking into buying my first set of tanks. I come across many but stuck with SMAW and Flux core welding mainly but now moving to MIG shortly. If willing, I'd sure like to connect and meet with you to learn more about these date markings if you're willing to share. I was going to start interfacing with Mathesons' but would be curious to learn if you would recommend a different place. Thank you again!

[@PranaTech]

Hi there! Glad to see another Tucsonan on here! The markings are pretty straight forward. Just make sure the date is within 5 years unless it has a star and then it can go to ten years. Even if it is out of date, Mathesons will still take it and only charges $15-$20 for the hydrotest when you exchange the tank. They are still by far the best to deal with here in town. 👍😁

Awesome video! Thank you for sharing this knowledge with us! Just did a quick search in my local area and found someone with a few 300cf tanks for $100 each. Are these bigger ones harder to sell due to their weight? And how much does it cost to refill these with the 75/25 mix?

[@PranaTech]

Hi Bernie! That’s a great deal on those 300cf tanks! Here where I live it’s about $58 to fill a 300cf tank. As for difficulty in selling the tanks, every area is different. The 300cf tanks only weigh 15 pounds more than the 250 so weight shouldn’t be a problem. The larger your metropolitan area is, the easier it is to sell them because the demand is higher for the tanks. Here in Tucson I could sell those tanks all the time for $350. Sometimes I have to wait a week but usually they sell in just a few days. I would call your local welding shops and see what they get for a tank and then undercut them by $100. This makes you some cash and gets the buyer a good deal and everyone wins. Hope this helps. 😊👍Don

I saw your video and picked up an empty helium tank (size 5) this weekend for $35. I'm trying to learn on a 1980 Eastwood Mig welder. Problem is I'm hoping to downgrade to a smaller tank. So far I haven't found a place willing to do the downgrade to a smaller tank. Second problem I'm having is the first couple places say they will exchange like for like (Helium size 5 for Helium size 5) but there's no helium to be had around here. Will they accept a tank with stickers removed? Then I can say it was Argon/CO2 and try and sell it like you do?

[@PranaTech]

I would try and find a shop that will exchange it for Argon/co2 but if not, I would remove the sticker and try it that way. Then sell it and buy a smaller tank and pocket the profits. $35 is a smoking deal. 😁👍 Where are you located?

[@calmseas9263]

Great video. I bought a full-size 125 tank on OfferUp. I wonder though, the collar has a stamp. I saw on another video with a word of caution about rentals being sold i.e... theft. This one doesn't say rental or anything. Any thoughts? Either way, thank you.

[@whazupmike]

After watching this video, I bought 320cf Helium tank. I called the local store and they said right away if it’s personal tank or rental. He says it’s most likely stolen. I check the tank and it doesn’t say rental but it does say Praxair name is on it. Do I assume this was a rental and wasn’t returned ??

[@PranaTech]

Hi Mike, what I do is take a picture of the tank’s marking and then show the guys at the welding supply and ask them if they will exchange it. I tell them that I am considering buying this tank. If they say no then I don’t purchase it. If you have already purchased it and they won’t exchange it then the only option is to grind off the markings and repaint the tank or cut the bottom off and make a garden bell out of it. Big garden bells are selling for $600 to $1200 in my area.😊👍

@@PranaTech used to be easy to have any tank refilled but it's changed in last 10 years. Gas companies here are picky. They only want to re-fill their own branded tanks. Usually you leave a deposit or lease a tank from them which can be expensive. eBay and market place are full of tanks for very little money. You can't even really weigh them in for scrap either as scrappers won't take pressurised vessels.

Wow, that’s a tough market for guys trying to make a living starting out welding! Leased tanks here in the US are very unpopular and have virtually died out in most areas because everyone figured out it was a scam. Sounds like that would be a good business to start over there. Filling tanks for shops that have their own tanks. For the price you are seeing for those tanks I would buy them up all day even if I couldn’t get them refilled. Over here people pay $600-$1500 for garden bells made out of old welding tanks with a custom artsy stand to hang it from. 😊👍

Hi, I just came across your video, I have been given 3 tanks. This guy just wanted to get rid of them, he does auction sales and I guess they would not sell. My question is, how do I tell what gas is in them? I live in Canada so things might be different here. I wanted to start using oxy/propane. My father always used oxy/ acetylene, but here in Canada you have to get a filling contract for acetylene. So I never bothered setting up my torches I bought some new hoses but before I hooked any thing up I wanted to know what was what. It has been a long time since I have used gas of any kind. I would appreciate any advise you could give me. Thanks Luke.

[@PranaTech]

Hi Luke, I would just take them in to a welding supply and exchange them for the gasses you need. They usually don’t care what gas the bottle was. They just purge them and refill them with whatever gas they need or sells best. I would think Canada would be the same.😁👍
