In this Instructable I will show you how to make a simple, cheap and effective HHO torch that can melt small pieces of metals like tin cans. This can be used in various applications it can be connected into your fire torch or in your car which is also known as the HHO Hybrid Generator which can reduce your fuel consumption although I don’t have a car I am still a 12 years old boy.


A lot of people are asking what and how does a HHO Torch/Generator works. It is simple a HHO torch/Generator separates water molecules into gas, now you will have a mixture of Oxygen and Hydrogen gas which can give a powerful kick or flame.


- You can connect this in a fire torch pin which I will show you how to make.
- You can use this for your car to reduce fuel consumption. But this will not be mentioned for this Instructable, it would be better of you Google it.
- You can use this to weld o melt thin metals

Warning: It is not my responsibility if any of you gets injured or burned so don't blame me for your mistake. Luckily I made some safety features which are already tested and prevents some common problems with HHO converter like explosions and implosions which creates cracks or even explosions. Hydrogen are highly explosive especially of you mix it with Oxygen. Batteries not included.

Be sure to rate this a 5 star. This instructions are very rare and hard to find.

Step 1: Materials

You Will Need:

- Vinyl Tubing/Fish Tank Tube 2m (50c)
- Air Tight Container x2 ($1) 
- Fish Tank Tube Connectors x3 (30c)
- Stainless Steel Plates x12 ($2)
- Wire 1m (20c)
- 12 Volts Battery (revised)
- Inflation Pin (10c)

Cool project, well written and documented. I've had a build for one of these on the agenda for a while, because nobody answers any questions about them. <br> <br>Compared to a normal torch how would the flame be, in terms of heat and gas flow?
This type of torch should produce 5000-6000 F
Nice ibble'! I really wanna try it but in Singapore, 12 year old boys like me aren't often seen cutting steel and making a torch...
<p>well now that you're 18, I hope you give it a try :) </p>
PS: The clingwrap pressure valve was ingenius!
This is awesome!! A must try for this weekend!!!
AWESOME! This is a very good Instructable! Thanks, I will try to do it!
such a nice job
Best guide on making HHO torches. Thanks this is just what I need.
Nice. I have something similar and used an inflation pin but I keep getting flashbacks. Any ideas? Does this happen from too little HHO flowing?
No, this just happens due to burning. The same thing would happen during welding except that you have a backfire/flame arrestor. With this design you will also not have stable PSI which is possibly another issue. Not using an arrestor is dangerous. You can either use an oxygen/hydrogen arrestor (used for gas welding) or appropriately a Gas Torch Mount Flashback Arrestor (I would suggest the latter but either would be better than none and the welding one should run around $10).
Thanks for the reply. I did have a flashback arrestor similar to what is shown in the picture - a jar with the gas running through the water. But the flashbacks kept blowing the lid off the jar. I tried to let it run for a few minutes first to see if there was a problem with air mixture. Maybe it's something like what happens on a vehicle? If there are any leaks in the exhaust the car will back fire. Maybe I don't have a well sealed line?
HHO is the recipe for an explosion the perfect mix of fuel and oxygen, to get a sustainable flame you need to introduce an inert gas to reduce the burn rate of the HHO, you need to add an air compressor to the system and as air has a high percentage of inert nitrogen gas you can achieve a sustained flame. I know a guy who is tinkering at HHO production and he has achieved a sustained flame by this method.
use sheild pro 31, will get a BETTER! result ;) ARGON removes impurity from the atmosphere ;) think about it, pressure + nitrogen, perfect! run at about 30 psi on a 4000kpa tank, your tank will outlive your plates! :P
<p>Ummm... Argon doesn't REMOVE anything. It is an INERT gas, as such it doesn't react with other stuff. What it does in welding is provide a SHIELD preventing regular air from coming in contact with the weld pool which in turn prevents all sorts of nasties such as oxides, etc. from forming in the molten metal(s) and the flux binds and floats up other impurities into the slag crust.</p>
I would say that the problem is that you have a complete recipe for combustion. A burn or explosion needs three things to happen. Oxygen, fuel and a source. The HHO is both fuel and oxygen in one, so having an air leak would not cause this problem. A venturi-type regulator like on some low-end grills would not do anything either. To be honest, the only flammable gases I have ever really worked with have been hydrocarbons, and usually the containers had a gas mixture too rich to backfire. I dunno how you can solve this problem, but the idea of PSI being a problem might help somewhat. Perhaps pumping it into a bike inner tube?
producing too much oxygen will kill a fire, you need a correct ratio to burn, you add more O2, and you can cool or even slow the burn rate down, but a no flammable gas like argon, burns but does not explode, thats why they use it in welders, it stops the vortex created with a burning flame, and takes the oxygen, and every other known impurity out of the weld, they use hydrogen and argon to get a hotter weld area. try it - you can pick up a small gas bottle for about $30 from Australians masters/bunnings, i use it for nitro cars ;) 20 argon / 40 nitro / 40 diesel, its a great mixture, and boy oh boy does it give a bang!, but i use argon to delete the need for brace in the chamber and to remove the carbon build up...... and my engines run almost 100 degrees cooler, stop engine was 250 - 260 now i can get it as low as 110, and add more fuel!!!!!
<p>try adding small amount of alchol to your bubbler it bwill improve the flame and less flash back a small fuel filter can be use as a flash back arrestor</p>
<p>great fun idea. I'm a welder and an electrian. this could be a tool to shrink wire wrap. thanks. keep up the good work.</p>
<p>TIP: put a small piece of a stainer or alike on the end of the pipe where the gas enters the bubbler. This should even out the pressure for a more stable flame</p>
<p>can I hook this upto a bunsen burner</p>
<p>IF you send enough electricity through it then yes</p>
<p>I don't know about how much this outputs, but I'd imagine a bunsen burner needs more gas for it to run smoothly.</p>
<p>What is the purpose of the bubbler? could I exclude it?</p>
<p>Yes, but you will be at risk of your whole setup exploding when you ligth the torch</p>
<p>Think of it like an opto-isolator or simple diode. While it could be removed and the torch remain functional, it's about as advisable as driving a car after removing the brakes and steering wheel., sans seatbelt If, for some unfortunate reason, your flame were to enter into the tubing (too close to your cutting surface or not enough positive gas pressure could both cause this (really, these are both the same thing)) it would travel down the tube and then -- in theory -- be interrupted by the bubbler. Without it, it could travel all the way back to your gas source. Remember, fire requires oxygen to burn, but we're supplying more than enough oxygen <em>inside the line</em> from the electrolysis to fuel our flame.</p>
<p>Fill bubbler up complety and its just a HH torch i would say</p>
<p>Can we run burner on HHO?</p>
<p>I get ans from reply @<a href="https://www.instructables.com/member/Divisible_By_0" rel="nofollow">Divisible_By_0</a></p>
<p>hey does it prevent flash back.....</p><p>when power supply is not enough to produce enough pressure in tube, hydrogen in the tube that u would hold will burst till the secondary small plastic bottle.</p><p>BUT IT WAS nice and handy. </p>
<p>Mixtures of oxygen with flammable gases explode with a loud bang on ignition!</p>
<p>And that's why we're using it. If you burn it in small quantities the BANG is replaced by a hot flame.</p>
<p>Does it really work? The last time i did such a thing the O/H mix exploded into the electrolysis container</p>
I was thinking of using lithium for the electrolytes and either a multi cylinder rig or a multi helix rig for the electrode. To be honest I don't know much about any of this and am just fancied by so I want to experiment. However, if I'm way off the mark please let me know. Also I was thinking of using a solar battery set up and solar heating with mirrors and possibly a lightly concentrated magnifying glass (if necessary) to heat up the solution. Also theoretically speaking wouldn't it be more efficient to have your little plastic wrap pressure release valves open up into a separate air tight reservoir. This should prevent total lost of the gasses as well as prevent the flames from burning wildly. Having said that you still want to add an additional pressure release diaphragm/ valve exiting from the secondary chamber. Any ideas and or comments are appreciated. As I said I know very little of the subject matter. The end result for me is to use it as a source of heat/ energy for a fallout bunker.
<p>mention sanding the plates pls</p>
Where did you get the stainless steel? I can't find it anywhere cheep like that
can you put a vid of it working in the 'ibble? Thanks
<p>12 you are amasing but i would have liked it working</p>
Could you fit a non-return valve to the outlet so pressure would have to build up before it opens? <br>I think the aquarium ones open around 1/2~2psi?
Yes you can!
Hey lol man...I'm not all science,kinda person...with that said...by now...you have a car? Just wondering,if or what this unit could do? Also you say u have plans for a bigger? Did I miss something? And what would it do as far as on a car?
crazypj, add a air pump the the mixture ;) you know the blubbers too ad oxygen :p, these run at about 5 - 8 psi, add a ball value too it, and that will give you a little more pressure, and a good oxygen and hho mix, you still need oxygen for fuel to burn in this atmosphere, thats why they have a oxygen tank on the space shuttles, because they use liquid hydrogen to send them into space, also, depending on your output, try adding small house, and a bigger bubblier :p
I had no pressure release system so mine exploded and parts whent everywhere
why do you not show it working?
Back then, I was 11 when I posted this guide. I didn't have a videocam before, nor a smartphone.
<p>have you improved on this design since then?</p>
<p>Would highly recommend installing two check valves (sure one is great but two is even better) one at torch end and one more near the tank. I found some cheap ones online like <br><br>CVU-2-KV</p>
<p>It would be a good idea for more safety including an arrestor too to the pipe. Even adding brass wool in the pipe to stop flame from explosion.</p><p>Thanks</p>
<p>Well done! I've been tinkering with hho for a wile now and I now have a wet cell made out of pvc with 10 plates of food grade stainless and it works wonders! Wilth my experience I would recommend that you use something other than salt or baking soda for your electrolyte: salt creates chlorine gas and is hard on the plates and baking soda produces small traces of carbon monoxide and dioxide wile it harshly eats away at stainless.</p>
