- Here is a "How to" on making compressed oxygen for a oxy torch. If you are using oxygen, hopefully you understand the risks involved and use the appropriate flashback protectors. Oil free is a must. I thoroughly cleaned the tanks that I repurposed. I have been successfully using this system for 10+years
Here is the link to the wire hose clamp video

So about 2 years ago I wanted to start blowing glass so naturally I needed more of a torch than just a propane torch. I discovered oxygen and as I was learning about the fundamentals, I stumbled upon this video. I was amazed at how simple yet genius your whole set up was. Like you, I've always wanted to be self sufficient. Well today I finally picked up a free concentrator and I'm so stoked. You inspired me and I really appreciate it. Cheers
Thanks heaps! Definitely has some risks to it. But you just need to understand and take due caution. Good luck with it

Hey I'll just throw it out there if you are working with small pieces of glass MAPP pro gas is more than adequate. Especially, if you have fire bricks for insulating the heat but when I'm in a pinch and need to patch lab glass MAPP works just fine.
I was partially relieved when you mentioned that your compressor is of the oil-free variety. Care must be taken that all components (fittings, hoses, tanks, etc.) that come in to contact with compressed O2 are cleaned for oxygen service. Failure to do so can be catastrophic!
Can you explain it, or is it just the plain old catastrophic fearmongering.
Nice to see a fellow Aussie getting about it.... top job bloke
You shouldn't use propane tanks unless you've unscrewed the valve and washed them out first. The scent they add to the gas is oil based and can pool in the bottom. It may not be a problem since it's VERY hard to get an ignition source inside of an air tight cylinder. Even still it's just bad practice to combine a fuel with a pure oxygen source in an air tight pressurized container.
I was going to say the same, you have to be careful that there's zero fuel contaminants.. Just get a old balloon gas bottle and an inline regulator, much easier
Mate!! You've restored my faith in young Aussies!!! Thanks for sharing
Hi seahippies, have you become a flat earther yet?
That's a genius idea with the bag a kind of buffer tank.
Thank you, great ideas presented well. I bought a used O2 concentrator a couple of years ago for this purpose but couldn't think of an easy way to pressurize it. I can work with your idea.
Excellent contribution, thanks for posting.
Very nice how-to video appreciate your time and effort thank you
Fantastic. I was wondering how to solve my problem and here we are. Thanks
Did you setup an oxygen torch?
F'n awesome!!! I bought a 5 litre/minute oxygen concentrator 2 weeks ago and have been thinking of ways to compress my oxygen to higher pressures that I can store for later use and use for studying/cutting as well as glass blowing. I had been searching around for CZcams videos or guides on google but was unable to find much until now! Thank you all look much. Fantastic idea. I know what I'll be doing tomorrow on through the weekend.
Glad to hear it bro. Good luck
I think just using a 4 feet diameter latex balloon that cost 3$ for storing the oxygen is much safer then compressing it in any tank, also 100 times less expensive.
@@simpledate you think filling a 4 foot diameter latex balloon is safer to have around a cutting torch that will have burning metal Embers flying around would be safer than it being in a steel tank what happens when a spark hits the balloon and melts through it
That bellows setup is ingenious.
Great Vid! Stuff has become so expensive , I am ditching the bottle, looking for a concentrator. Pressurized O2 has been beyond my scope. Thanks ! This is very encouraging.
You the man. This is awesome!
Dude this is awesome! Can you make another video with a step by step please? I’m looking for a way to do almost exactly what you’ve done there and I want to copy your method
The only video I’ve found helpful too what I’m trying to conjure up
did you succeed?
To be honest I forgot what I was even working on going back on this lol
Now that’s cool ingenious!!!!
One word-- BRILLIANT!!
That is brilliant Mate! I have been looking for some method of doing this and now I have found it. Many thanks for sharing.
I was concerned about compressing the Oxygen until now, the diaphragm style compressor had not occurred to me until I saw your method. I have old oxy bottles thrown as they were out of service for full pressure, however still fine for a couple of hundred pounds or so.
You have given me an idea however on how to make a piston type pump that is isolated from oil of any sort that will pump to much higher pressures.
Thanks heaps for sharing this GOLD! John, Sralia mate.
'Mate' looks a little unnatural, when written, I think, especially with the capital. I'm not sure why. Man, Bro, Dude, and Home-slice, all fine.
Awesome bro thank you 😁
Thank You Bro . looking forward to cutting steel and heating metal parts for the shop
did you succeed?
Cool video. Double thumbs up.
Thanks, great idea
Great idea. A couple of comments anyone that wants to attempt this should consider. 1) LPG tanks contain residue of Ethyl Mercaptan which is what makes LPG smell like LPG 2) consider getting an empty oxygen tank on gumtree etc. plenty around, many for free 3) You should connect a vacuum pump to your circuit. Easily done with a refrigeration manifold and pump. You should not contaminate the pure oxygen with the air in the pipes and tank. 4) OXYGEN is explosive when it is in contact AT PRESSURE with many oil and greases including SILICON oil. You have used a oil free pump which is excellent, however this would also be vacuumed before taking the oxygen 5) LPG and oxygen is not as dangerous as ACETYLENE. If you ise acetylene connect FIRE ARRESTORS to both tanks
Awesome thinking love this. It good to know things
dude, your the end of a leg (legend), thank you so much for this idea, i am for sure doing this, so fed up with buying bottles all the time to, thank you bro.
Ashley Smith : cheers mate. Good luck with it!
manny thanx brother ;o), will drop by when im done mate.
Awesome video thank you
If you can score a Homefill oxygen compressor you can refill high pressure cylinders. I use medical cylinders for light mobile LP cutting but currently transfill them from larger cylinders (oxygen is cheap enough commercially and I've two gas suppliers within 20 minutes). Homefill compressors are often used with the (ripoff priced) integral regulator medical cylinders which are not repairable but you can harvest their QD male if desired to connect to the compressor then buy a whip and proper fittings for your cylinder. I use a Tee so I can use an ordinary oxygen regulator to monitor pressures and dump the line after the cylinder is full. Pilots use "transfill whips" similarly.
you are very clever. gday from California
Thanks heaps mate!
Wow. Thats awesome. I have an O2 Concentrator I bought for $5 from an auction (5l/min). I verified it by blowing it on some burning chopsticks. Ive got MIG, TIG, stick welders but not Oxy/Acetylene (have the equip, but no tanks). I only need it to get something cherry red every so often. Im thinking about this route.
They also make concentrators that can put out up to 10L/min. I have 2 patients at work on them.
Do you have a video showing how you made the tilt switch?
Thank you sir!
Amazing !
Very awesome!!!!
Peter Thomas-Hall; Tyvk 4 sharing ur ideas! I have never seen desiccant used in quite that way before; my background is in airbrushing, and I live in a very humid area, so a moisture trap has traditionally been sufficient for my use, since I haven’t actually been storing gasses. So, I have to ask if a moisture trap might work in a setup that’s similar to yours; and also, how do u maintain the desiccant that u use-does it just get emptied from its’ container and re-dried in an oven, like a person can do with silica gel?
Glassblowers been doing this with home fills for years. Great video
I have a concentrator, and i want to do a system on my on. Do you have some info on that
flashback, most important. your good workshop can blow up without it.
Awesome!
I have a 10L unit, reckon it would be enough to cut metal with?? I found it and a 5L unit on the side of the road and both work just fine. The 10L even has a battery backup built in that still works lol. The silica gel beads are def a good idea. But the compressor and tank idea were awesome thanks.
Hi, thanks fo the video... Was looking for the link to the hose clamp video, but it's not in the discription. I liked and subscribed and will check out your other videos.
Just in case you never saw it,
czcams.com/video/rC5GcER3wk8/video.html
Nice one 👍
Just my 2 cents. Long time auto mechanic my welding gas supply guys once told me Just. Even. Opening up the oxygen tank valve too fast can’t cause an extreme fire as it rushes past the regulator and mixes with oil ect forget exactly the comment , but tread very carefully those guys know what they are talking about at the bottled gas supply houses.
That's mostly true, but the guys at the bottle gas supply use oxygen cylinders that are compressed to ~2,400PSI, this guy is using
Nice 👍 very smart.
Can i use it for fish tank?
Hope you have flashback protection
PETER: QUESTIONS: I have little experience, unfortunately, so I apologize. 1. I heard somewhere that air compressors are often 'leaky', compressing some (of course) but otherwise losing something like 30% of the air one tries to compress. Is this the case, or was I misinterpreting what I thought was going on? Is it 30% backflow and therefore inefficiency, not leaks proper? If it does leak said gas, does it matter for these purposes since it's just oxygen into the air from whence it came - just a little wasted energy, nothing more? 2. When I look at compressors they always seem to have a large open grill, but you seem to have hooked up tubes. If I remove the grill part, will there be a port where one can hook in a tube (and is that how you did it)?
Brilliant.
Some of those generators have output rating at 20 psi so you can connect directly to the torch. I've been able to braze copper tubing up to 1 1/2" that way
Bravo........tire tube Simi........cool it with dry ice......make liquid o2........cheers
Ingenious.
Can I ask you why are you not connecting the big cylinder to the compressor all the time to fill it up?
Do you know all the models of oxygen fill machines a private user can buy to refill their oxygen tanks for their torch?
Smart move with the tilt sensors
THANKS FOR THE VIDEO!
Nice!
It may be oil free, but I wonder what effect the oxygen has on the other components of the compressor. Some have polymer based diaphragms.
what line presure do you get out of your oxygen generator pete?
Does the oxygen concentrator have enough output to supply the intake of the compressor without causing problems?
Is the on/off switch like a bi-stable vibrator circuit so when the switch to start compressing is activated, allows power to flow to the compressor, compressing the oxygen into the tank, deflating the bag eventually hitting the off switch, and cutting power to the compressor side of the bi-stable?
Otherwise, the compressor would kick on, compress some oxygen, deflate the bag just enough to unpress the switch, and rapidly repeat itself.
I guess im just interested in the electical side of how you turn the compressor on and off. Kinda wrote a lot there and I hope it made sense.
Very smart
thats awesome
Hi Greate video. I like to make a system like that for glassblowing. But why do you have the system with the bag? Im not sure that i understand it right. Are you filling the tank on the generator with oxygen
Is it important to use a dessicant if I'm refilling O2 tanks for agricultural use? I use them to infuse irrigation water with O2. Thanks!
Would those HHO generators work in this case if you couldn't get your hands on a medical oxygen maker?
How long does it take to fill the compressor tank
Medical grade O2 cuts so much nicer than standard welding grade O2.
Can you use this same setup to fill a "E" Size Aluminum 680 Liter Oxygen Cylinder at 2200 PSI? what kind of oil-less compressor is needed? the dedicated oxygen compressors of this capacity cost $5000!!
I believe that you believe that it will cut metal are you ever going to make a video demo please when you have the time that will be awesome good day mate cheers
Dive buddy of mine tried generating his own breathing gas (nitrox) and had not O2 cleaned his equipment properly and nearly burnt down his property. Anyone who thinks that this stuff is safe is wrong, but it will be okay until it is not. That is when you find out why it needs treating with respect, and why there are no cutting corners.
If I was him, I’d be using an empty G size oxygen bottle as the holding tank after the compressor. The lpg bottles have a lot of contaminants left behind from propane/butane mixtures.
Skill issue
How much are them machines
Can you go in depth on the electronics please
Thx.
Can u help me find a oxygen generator?? Can not find a cheap one
That bag deal had me convinced you're too smart by half. But the desiccant in the compressor tank fixed that. :) (use an inline on the output - I know you figured it out.) But it does beg the question of how the water got in there.
I found about a dozen of those machines in the park trash bin about that 2017 timeframe. They were from a rental house.
wow what a great idea. I was actually a little confuse how you draw bag of oxygen into air compressor, until i realized you have another tube coming out of the bag connected to the rear side of the compressor. When compressor kicks on, compressor uses it own power to suck the oxygen from the bag into the tank and stored it there. All make sense now~~
Where do you connect the hose coming out from the bag of oxygen to the air compressor?? I don't see how the oxygen goes from the bag through the compressor into the store tank . Please help !!!
Make sure to use flashback arrestors if your oxygen has too much other chemicals May flashback maybe you scuba pump 2 high-pressure cylinder
Make a much larger bag and put a massive amount of desiccant on the bottom of that. Should keep it from reaching the compressor.
Hi, I ordered an oxygen concentrator for a small torch, I will use it at its normal pressure. The configuration is propane-oxygen, according to tea should I use a protective valve on the pipes? The low pressure of the machine (max 1 bar) on the oxygen line could create problems with the safety valve? A thousand thanks.
did you succeed?
what type of desiccant are you using for the air filter and that of which is inside the compressor? just straight silica gel, zinc?
Just silica. There are definitely better desiccants, but it works fine.
Just what I've been looking for! Does it work with methane - oxy torch?
Connect one and see. Glassblowers routinely use oxygen concentrators without the additional apparatus and run them in parallel for greater volume.
What did you do to connect the oxygen concentrator to the air compressor? I have a similar air compressor to you but it doesn't have any sort of air input, and I can't find any compressors that take an air input for a reasonable price.
did you figure it out?
Where do you connect the hose coming out from the bag of oxygen to the air compressor?? I don't see how the oxygen goes from the bag through the compressor into the store tank . Please help !!!
The inlet of the compressor. Usually they have sound mufflers there so look for that.
So how you get the oxygen from the concentrator to the air compressor?? What kinda fittings you workin with??
Mostly nitto style fittings
I saw someone on CZcams that was making their own oxygen and hydrogen from water and was compressing them separately with like 12v compressors and a similar bag system
Is there any chance the compressor might create a spark and blow itself up? Might want to be on the other side of a block wall while the compressor is running just in case...
There is.
Brilliant, thanks! Have you used HHO generators or torches, don't know how they compare but I've heard they're great! Cheers!
There is some risk here. The risk is not compressing oxygen or some minimal propane let in the tank. Compressed gasses are safe if used properly. The risk is oil leaking out from the compressor. If you happen to get the correct ratio of oxygen to oil vapor....badness. That is probably unlikely but it is possible. I am wondering if there is a safer type of compressor to try this.
So it is an oil free compressor, and I opened it up to check. PTFE seals. That is mandatory
@@paliaspip Nice work.
Oilsssss in the lpgg bottle.😱🤬💥
Amazing Dude! … how long does it take to fill up that big tank?
Takes a few hours, but eventually gets there.
Are you not concerned about any potential sparking when cylinders in the air compressor moves?
Oxygen needs a fuel source in order to react. The compressor is an oil free type. If there was oil, that would be big problem. Likewise with the cylinder, needs to be be completely free of oil
Thank you sir , do we need flashback arrestor when we use oxygen generator and gas for soldering jewelry ?
100% needed. Very important
Rio Grand . com says no flashback needed with the Oxygen concentrator.
I hope you carefully cleaned off the propane tank from any gas, grease and paraffin decomposites inside? You probably also know that pure oxygen (esp. when compressed) tends to react very impressively with all oil, grease and alike stuff? You are lucke nothing bad happened so far. But - believe it or not - i have similar ideas :-) I guess oxygen at 5 or 10 bar is not as agressive as it is at 200 bar from industrial tanks. The regulators can suddenly explode when opening the valve because of slightest contaminiations with grease or just dust and debriss coming from inside wear! It is rare but such incidents have been reported esp. from aluminium regulators. So take care!
It's not really a problem so long as you don't just throw the valve open. You can cause that kind of explosion with an argon tank if you screw it up just right.
How would you clean a tank like that from the inside??
@@marceloovg1873 i use some solvents like petrol, benzine e.g. and a vacuum pump. Let the solvents rest for some days and turn the tank every now and again, also apply some heat gently. Let the solvent drop out - use some pressure to get all out (turn the tank). Then evacuate the tank and apply heat gently. Let it on high vacuum for some days. You can be sure that you have 99.9 % of all solvable debris out of the tank.
@@richardnanis thank you for the information
Its great!!! Sir can does the oxygen output from the oxy generator continously? So that i can directly put it in a reservoir tank.. Instead of bag? Thanks
Yes, it is continuous but very low pressure
Thanks sir. To pressurized... I need to set up another high pressure comoressor to refill at least 250 psi...using two units of oxy generator
..Would it be possible sir? Thanks again.
Salut! Moi c'est Diallo depuis ingénieur Biomédicale j'amerai voir comment faire un entretien général sur les concentracteur d'oxygène over flow
What is the name of that oxygen generator? Is it a "consintrator" is it producing hydrogen as well? You said, "90% oxygen"
Have you tried cutting with it. To my knowledge you need nearly pure oxy for cutting as medical grade is not pure enough. Can you please let me know if you have had luck cutting with it.
Yes! Cutting works like a charm. That's why I wanted to pressurise the Oxygen. You only need 40psi oxygen to cut, but 100psi crams more in the tank. I found no appreciable difference when cutting with the 95% pure medical Oxygen, compared to the 99% pure bottled Oxygen
Why are the machines so loud?how can you make it be quiet, no so loud 🤔
I think you forgot to post the link to the video where you show how to make the hose clamps.
Here it is czcams.com/video/rC5GcER3wk8/video.html
good .gues👍
awesome bro, any more of those available. the cheapest one in adelaide is like $2000.
Clayton Revie I purchased a develbise 5l/m oxy con unit for $100 used on craigslist. I have been happy with its performance when added to my oxy fuel torch, but need higher pressures and a store of oxygen for cutting. I had thought about running my oxy con output through to a compressor inlet, but doing so would damage my unit as a compressor would suck air through the oxy con's molecular sieves. Now I know how to overcome that problem. Hopefully you too can find yourself a used an inexpensive oxy con unit.
If I have 5 oxygen units, could I get enough if I ran them simultaneously? Incoming video...
TheRainHarvester no. You just need one and a a way to compress it
