HHO Torch Tear Down and Use

[@Killianwsh]

Hey Rob, I've got almost the exact same HHO torch (It's also known as KNALL gas. there are some very interesting videos in German on the subject) . The primary difference being that mine has a generated pressure gauge on top of the bubblier , where yours has the manual pressure release valve. I think you might be getting poor performance if you haven't let the pressure build up until the pressure switch inside kicks the machine off. It will need to run for a couple min. initially and then will take between 30sec to a min to build pressure back up and kick off again when in use. When the pressure is built up fully and your tank is close to full you'll have shorter runtime as there's less pressurized gas avail. , however , When you have it at full pressure you'll have about 30sec of full gas pressure to work with and what it can do is astonishing! Try just turning the machine on and let it run till it shuts itself off. then have a empty aluminum soda can ready. you'll likely have to work fast to witness the full effect, but when you light the torch, spin it open quickly and pass the mini light saber across the face of the can. It should slice through it like tissue paper! then shut the torch off and try the same test with the lid of a steel soup can! It's not quite as impressive, but it's CLOSE! Now for the first of the very curious properties.... let it build up pressure again, light it and open the valve as before, but instead try passing your fingers quickly but not FAST through the flame (Yes I am serious!) lol with an oxy/ propane or acetylene torch with even close to the same cutting power you'd 3rd degree your fingers almost instantly, but this flame feels no hotter than a pocket butane lighter! I'll see if I can post a video of me doing it with my torch as well as the can tests later today or tomorrow. :)

Hi Boss Terry here thanks for video It brought back memories from the 1980 s when I read professer Brown added Epsom salts or maybe it was bicarb soda to the water and welded a bronze tube to a housebrick and no scientist could explain why cheers

[@Scipiworld]

Key thing to note is that electrolysis, while one of the most versatile tools in the chemist's belt, requires very high amps to produce meaningful quantities of product. So the reaction for alkaline water electrolysis is as follows: Cathode: 2(H2O) + 2(e-) -> H2 + 2(OH-) Anode: 4(OH-) -> O2 + 2H2O + 2(e-) Overall: 2(H2O) -> 2(H2) + O2 Now we see here that we need a mole of electrons for every mole of water we break. Every two electrons liberate two hydrogen atoms and one oxygen atom. The charge of a mole of electrons is Avogadro's Number times the charge on an electrons, so one mole of electrons is Faraday's Constant at 96485.33C/mol. Amps are just coulombs per second, so at 20 amps, this device here is outputting 1/5 of a millimole of hydrogen per second. That's not even a quarter milligram of hydrogen fuel into the flame every second. Now hydrogen has remarkable energy density, so it doesn't take a lot, but this amount of fuel is super tiny. The secret is to get the most out of your electrons. Electrolysis of water is 1.23V, so the cell voltage should be as close to that as possible. 1.7V is great for high efficiency cells. Anything too high over 1.23V is wasted as restive heating in the water. Two ways to do this: Option one, get very high surface area plates in close proximity. This drops the cell resistance to allow for very low cell voltages, closer to the 1.23V ideal. The other option if you don't have a source capable of low voltages and crazy high amps is to wire up cells in series. Of course, continue to aim for close, high surface area plates to minimize resistance, but then wire up each cell for an optimal voltage drop. Also a pro tip: try separating the hydrogen and oxygen gases. Brown's Gas (HHO in 2:1 ratio) also combines with atmospheric air and leaves unconsumed oxygen, making an oxidizing flame that likes to cut stuff. A ratio of 5:1 is great for welding and can even clean up rust quite well since hot hydrogen can reduce iron oxide. Fe2O3+3(H2)->2(Fe)+3(H2O). Separating your gases also makes them storable (HHO is explosive and bad to keep around), so you can compensate for the overall slowness of electrolysis by generating gases while not in use.

[@UpcycleElectronics]

I'd love to understand a practical HHO separation process from the top down and in laymen terms. I was super interested in messing around with this a decade ago, but never got very far past a simple working cell. I was curious about off-grid solar energy storage using electrolysis for excess energy storage. Separation of the oxygen is obviously critical, but doing so with cheap, simple, easily accessible DIY technology was something I never figured out.

[@Scipiworld]

@@UpcycleElectronics HHO separation is something that is easy to pick up, but hard to perfect. It's worth experimenting with different set ups until eventually landing on something that works. First, you need to select the right electrodes for handling the conditions of your cell. The cathode will produce hydrogen and the anode will produce oxygen. Oxygen in the air is O2, or two oxygen atoms stuck together, but when performing electrolysis, there is a fraction of a second where the oxygen is monoatomic without another oxygen atom. This is very unstable and will oxidize the anode easily. This means steel electrodes will rust super fast, as will many other metals. Some electrodes such as nickel will catalyze the reaction, such as nickel cathodes. Second, you need to select an electrolyte. This will determine the chemistry behind how the cell works. Pure water doesn't conduct electricity, so an electrolyte is used to improve the conductivity of the water by adding ions. Unlike wires which transmit electrical charge using electrons, electrons don't travel well through water and the ions in the water do the moving of the charge. If you use an acidic electrolyte, hydrogen ions transmit the charge, if you use an alkaline electrolyte, hydroxide ions transmit the charge. Be careful when selecting your electrolyte, some electrolytes like to compete with water in electrolysis. For example, if we use salt water (NaCl) as an electrolyte, the chlorine beats out the oxygen and your cell will produce chlorine gas instead of hydrogen. My personal favorite electrolyte is a 25% solution of potassium hydroxide with a nickel cathode and a graphite anode. Now you will need to evaluate your cell. Consider the following formula: Vin = VH2O + IR or R=(Vin-VH2O)/I Vin is the input voltage VH2O is the electric potential of water electrolysis, this is 1.23Volts I is the current in amps R is the effective resistance of your cell Your goal as the experimenter is to make R as small as possible. Maybe you change your electrolyte or adjust the concentration. Maybe your electrodes could be changed or maybe they are corroding from the conditions in the cell. Maybe you can try getting the cells closer together. Maybe you can improve the surface area of your electrodes. Lots of options. Safety tip: Make sure your electrode is compatible with your electrolyte. Aluminum in strong acid or strong alkaline will produce hydrogen, but the aluminum will also aggressively react with the electrolyte. Always start small.

[@reincarnatethylacine3745]

Hi Rob. To change the heat of the flame you can play around with different solvents in the bubbler. Water seems to be the least efficient and I've played around with various mixtures of acetone and alcohol with mixed results. A flashback arrester becomes absolutely essential with volatiles in the bubbler . My small machine is supposedly capable of generating 150 litres of HHO an hour with a 5 litre electrolyte reservoir, so I'm guessing that your example would be somewhat proportionally less productive. If that is the case I wouldn't expect too much of it as I have come to consider my 150 litre machine as a bit of a toy. Never the less I was encouraged enough to splurge outlandishly on a 400 litre per hour machine with the goal of welding aluminium. The bigger machine only arrived quite recently and I don't really have any experience with it. With water in the bubbler it was struggling to overcome the oxide surface on very thin 2024 aluminium but more experimentation is to come.

[@brucewilliams6292]

I sincerely appreciate your taking the time to make this video with the tear down. I'd love to have a torch setup like this if it was powerful enough to do some brazing ect. but for now, I'll have to stick to gas. Thanks again.

[@ReWir3d]

Hello, Robert. Love Your videos! Many years ago I was working on something related to glass blowing and a group had developed an HHO torch but were chary about providing information on their process. We sussed out that it was some kind of resonant cavity that perhaps when pumped along with the DC power would liberate HHO in considerable quantities; a lot quicker than any torch could handle!

[@verdantpulse5185]

To see the flame better, replace the water in the flame trap with alcohol and a trace of boric acid. The boron entrained will make a visible green flame. It's made for jewelers in areas with tight controls on compressed fuel gasses. With no stored fuel, the explosion hazard is minimal.

[@universebecomingltd]

* high five * on the blind installation after 12 years, you may have me beat procrastination wise! HAHA! 🤣🤣 The torch with the red and green knobs is called a Smith Little Torch. Just about every jeweler on the planet has one of those, including myself. Given that the hydrogen torch is a Chinese model the Smith Little Torch is most likely a Chinese knockoff. In fact, it's actually pretty difficult to find somewhere to buy one that isn't a Chinese knockoff. They typically use propane and oxygen.

[@ThinkingandTinkering]

interesting - thanks for that mate

[@waynoswaynos]

That's not an HHO torch, its designed for health purposes. The gas is bubble through water converting the water to H3OH, they say. Its rejuvenating. So its not just a flash back arrester. Also a cannular is worn and the gas is breathed for lung problems and general wellbeing. You can for example put a bag over your forearm and pump the gas into it and carpel tunnel goes away. Spray it over burns and they get better fast. Its a poxy HHO torch but excellent for its intended use. If you want a real water torch find Severs on youtube and see what that dude sells. Very good machines big and small. Big flames. Very clever inventor.

[@flashlit123]

That looks like the exact HHO torch I have. I haven't used it much but it does work to polish the edges of plastic if you are careful not to heat it too much which causes bubbles and burning. I also used it to solder heavy copper wire. Tried to solder copper pipe but couldn't get enough heat for that. I used sodium hydroxide drain cleaner and just adjusted the concentration to get a reasonable current draw. I drilled one of the torch tips out slightly bigger but it didn't produce enough gas to keep the bigger flame burning very long. No idea how long the device will last but it is an interesting idea that has some uses. Blowing some bubbles into soapy water is a simple way to show the explosive power of the mixture of hydrogen and oxygen. Would be interesting to see the difference between the sodium (or potassium) hydroxide and urea electrolyte. This gas CAN float a balloon but you might want to try the soap bubble experiment before deciding to risk a balloon's worth of the gas.

Hi, i built my own years ago ! you cant see the flame, but it can get very hot, the gas is Very explosive, try sticking the torch into a plastic glass full of slightly soapy water and you will get bubble forming on the surface, put some safety goggles on and light the bubble with a long lighter, if you thought the starting welding made you jump ??? lol

[@darrenpyott6291]

I’ve got the same or similar one, basically an electrical gas bomb! No flashback arrester for the HHO gas it generates. If the flame was to flashback down the pipe to the bubbler you would be looking for some new underwear and possibly first aid kit to remove shrapnel! It’s a great tool for polishing / finishing plastic to give a glasslike finish. As you discovered, also good for removing components. The flame is small but extremely hot and can be used for small brazing jobs or silver soldering small items. A useful tool but seriously, put a flashback arrester between the bubbler and torch head. Fill a latex glove with the gas, tie it, put it on the ground and light it with a blow lamp at arms length, you will see what I mean! (Ear defenders recommended!) imagine that power in a sealed metal bubbler!

yea been thinking of building one of these diy style. yea the hydrogen flames by itself isn't much use. give it a good oxygen source to go with it and you can cut through just about anything. although those off the shelf units are weezy at best. needs a VERY high flow rate to really get cooking.

A local plumber here a few months ago thought he'd save lugging oxy and lpgas bottles to a job so he got a good flame, put it out and topped up a small lpg bottle with it... easier to carry one small bottle, right?

[@transistor754]

@@ThinkingandTinkering I'm just saying that having a stoichiometric mixture in one container like these HHO generators is an explosive situation as opposed to mixing at the tip in air as per conventional two gas torches where each gas line has a flashback arrester. P.S. I really like your channel, please keep up the great work.

[@TheEmbeddedHobbyist]

The torch is a jewellers torch, very hot flame but little power I was one for working with silver. Normally the bubblier is filled with M.E.K or something like it to control the flame temperature as the torch control is only on/off. You mix the other gas to alter the gas/air mixture. Great for small work but no good for anything bigger than a ring. The other torch is a Smiths Little Torch, either oxy/acetylene or in my case oxy/propane. A quick google will show you all the different heads than can be added to the torch.

Is it really just putting a straight steady amperage and voltage into the electrolyser? Does it actually say to use a electrolyte in some instructions on the machine or did someone tell you to do that? I was kind of surprised and disappointed it wasn't using a pulsing lower amperage signal especially since it uses the PWM chip. can you actually measure the signal to the chamber without any electrolyser in it?

I have one, and modified it for Hydrogen therapy. That's apparently the fountain of youth.. Here's what you do: instead of 15% lye by weight, just use a tiny bit. less than a teaspoon. So little that the amperage gets only up to 3 amps. then add two bubblers, one high one for washing the gas and one for drinking water. After the second bubbler you can connect a canula for breathing the gas. I use distilled water for all. With more lye, you get more gas, but it needs to stay below 4% in the lungs so that no explosion could possibly occur. With more lye or more time instead of a canula you can fill up a bag to apply hydrogen to a limb, ideally something like a veterinary plastic glove. Careful, because the gas is still explosive, avoid static electricity, but that's just a loud bang without serious damage. an explosion in the lungs would be serious.. Look up the health effects, podcasts by George Wiseman and others.

[@lisakingscott7729]

I was looking for a way to make oxygen for gas welding, rather than having to buy consumables. I remember seeing this video ages ago and did some quick calculations to see whether something like this might be practicable. Doing the calculations of the amount of oxygen and hydrogen it could generate, if running at 3kW, assuming relatively decent efficiency (it won't be)... 237.26 kJ/mol water => 237.26 kJ to electrolyse 18g water. 3kWh = 10.8MJ, so 10800/237.26 = 45.5 mols per hour of HHO or x 18 = 819g/hour of HHO produced. Comparing with typical oxy acetylene usage rates, 45.5 mols oxygen is over 1000 litres per hour at STP. This is way more oxygen per hour than would be needed to weld 6 - 7mm steel with oxy-acetylene, which most tables reckon about 650L/hour. Given the inefficiencies of electrolysis, even if 30% input energy wasted, this could actually be useful. A simple rectifier and thyristor circuit could be used to control the gas production (DC to allow oxygen and hydrogen to be collected separately). So this if my calculations are right, a scaled up version looks like a practical replacement for oxy acetylene, or if the gases were collected separately, the oxygen could be used with a different fuel and the hydrogen collected for other uses. I'm not sure whether hydrogen embrittlement may be an issue welding steel.

It may have already been said, but the torch with the two nozzles is probably designed for separated fuel / oxidizer tanks where you can then adjust the output of each to control flame properties. I suppose two of these units (with oxidizer / fuel already mixed) could be put through it for increased flow rate capability though. You say the power supply is putting out 12V. Surely that is not over one alkali cell? I think that would be horribly inefficient. Maybe there are multiple neutral plates in the cell? If it was 12V over only two electrodes, I'd think no wonder the anode has corroded.

the two pronged torch might take an oxygen input to increase the flame/temperature. just a guess.

[@grahamh4960]

Doesn't seem to do a lot for a big unit. I'm sure you can beef it up a bit. Thanks for sharing.

[@ThinkingandTinkering]

I will give it a go for sure mate - cheers

[@colouroboros9993]

Have you tried using the flame to power a stirling engine, which in turn powers the torch? lol - or creating steam to power a steam engine?

[@Bobsry16]

You would need to get a lot more of the energy stored in HHO and steam.

[@markwright5112]

is that power supply pwm or just an 12v inverter?

[@hansscholte5472]

Its straight DC but a PWM would increase the efficiency much. Pulsed DC would give an even better result but takes experimenting due to all varieties like concentration of electrolyte, type of electrolyte, setup of the cell (number of plates), etc.

[@tisstuart]

The torch with the second input is for the oxygen. Also derived from the proccess and should be piped into the exhaust side of that system. Just drill a hole and soldier another tube connection. Plus if it had a reservoir it could get pressure. Those are great for small things and worthy of a better valve that and a sparker from a lighter.. I dare you to tamper around and build it up.

[@ThinkingandTinkering]

I was thinking about it mate - so not much of a dare lol

[@captainmidnite93]

Does it make a good pot of tea? My college girlfriend's dad, head of GE's E-lab in Syracuse, (first Steinmetz award nominee) used to get a kick out of using a pea sized hydrogen torch to boil water for his coffee..

[@ThinkingandTinkering]

no w that I have to try lol

[@mindbomba9923]

Ist the Steel of electrolysd stainless steel?

[@sadaavedan]

It is from Taiwan and officially sold as a jeweler's torch. If I remember correctly it costs around USD$140 or so. Its interesting use is actually not as a jeweler's torch but rather as a Browns gas generator for health. You need to add couple more bubbler bottles to completely take out any residual rye in the gas and it can then be bubbled through drinking water, breathed in directly. The most interesting use I have read about is the ability of the gas to cure skin ulcers as well as phantom limb. There is this company Eagle Research Corp that buys these removed the power supply to a more efficient one and a few more safety sensors to detect low water condition, some robust flame arrestor as well as a timer to run the device for a specific time and sells it for, hold on to something, USD$2,500! That company recommends a 20% Sodium Hydroxide solution instead of Potassium Hydroxide.

[@ThinkingandTinkering]

yeah I did look up the price - it's not that much - I think it can be rejigged for sure

[@DanielSMatthews]

I thought that the point of adding trace amounts of acetone was simply to make the flame visible, you get the emission lines from the carbon in the plasma/flame.

[@ThinkingandTinkering]

I have no idea mate - the guy I watched said the flame burned at a different temp

[@DanielSMatthews]

@@ThinkingandTinkering I'm pretty sure it is the carbon emission lines, it would change the heat transfer as there is more radiative transfer as well as the usual conduction from the hot gasses. Oxyhydrogen burns at around 2,800 °C and I can't see how that would vary much with just traces of something else in it, other than the heat transfer aspect.

[@krisgair5863]

Just subbed, very interesting vid, you remind me of my old science teacher, :)

[@bikerfirefarter7280]

You had Old Science classes?

[@krisgair5863]

@@bikerfirefarter7280 yeah, but my teacher never took apart a hydrogen generator, nor did he tell us what hydrogen was, so I guess Robert is like him, just way more intelligent and cool 😎 😉

[@snoddyification]

That was interesting. thanks.

[@mariusofearth2474]

If u dont want it to rust oute to fast use distilled water . Mineralfree i guess

[@SatinCamaro]

Is that 12 amps 12vdc ? 144 watts?

[@ThinkingandTinkering]

yep - it's not a lot is it

[@paulnothnagel2136]

I like you just for the blinds sake. All the distractions

[@serfer4219]

the only thing i see missing is a flashback arrester that goes after the bubbler and before the torch

[@ThinkingandTinkering]

doesn't have one mate and from my looking at similar models it's not part of this little set up

[@Evomindcom]

Since the reactor runs on 12 Volts, I thought I'd hook it up to my car battery. However, apart from the fan in the rear nothing happens.. No Brown's gas production at all.. What's going wrong?

[@hansscholte5472]

Rudolf, maybe you mixed up plus and minus? You should at least have a few amps available from your battery, the more concentration on electrolyte, the more gas. Maybe your plates are full with holes/ rusted? The current than ‘runs away’ through the holes.

[@Evomindcom]

@@hansscholte5472 The reactor runs on 24 Volts, not on 12 Volt.. That's why it didn't work.

[@ronniepirtlejr2606]

You know what a flame arrestor is nevermind!

[@ThinkingandTinkering]

that's how came mate

[@jwioo]

I think the alternative torch would accept an oxygen line, which would make all the difference.

[@ThinkingandTinkering]

for sure mate

[@aleksandarpetrovic6613]

This cell is not efficient, but I am curious what is inside. Is anyone cut it to see construction? I just saw through the cap, plastic housing of electrodes 🙂

[@mohamedmohamed-mw7mu]

مهتم بما تصنع

[@go4acro]

Yes very interesting

[@eulusgarza5765]

Is there a crucible material which will not react in the presence of HHO ? (Graphite is consumed into CO2)

[@ThinkingandTinkering]

dunno mate

[@ARandomTroll]

try ceramic ones like aluminium ot zirconium oxide and don't keep it pointed at the same spot

[@rymannphilippe]

Maybe it is used for melt Glas and melt Glas together?

[@ThinkingandTinkering]

I dunno mate - they do seem to be growing in popularity and I think if played around with they could have a few uses

[@IamJiva]

aceton+water 1:1 mix in bubler, and stronger alcaline sol-n(maybe KOH even better)for higher as possible current you will cut at least tincan(skimed milk,sweet corm etc) and redbull duraluminium 0.33l cans must be like that, my simple design do it at 130Wt, first opening some more difficult, maybe 20sec needed, than can cut 1mm/sec speed, burning road notch ~1mm width usefull for making termocouple, and for welding nichrome with steel -for good connection, but useless for welding mechanically(instead of acetylene/oxigen) as i know now, may be there is some secrets unknown...

[@IamJiva]

alcohol and petrol - not good saturators fuel as i experience - big flame without heat only producing

[@paulleftwick7782]

it can vaporise metals and burn nuclar waste or make diamons

[@Jamesvandaele]

I used mine with MEK in the arrestor and never had an issue with it, got hotter than my regular oxygen/propane torch, but mine might have pumped out more gas.

[@ThinkingandTinkering]

personally I think if you are mixing volatiles in the bubbler you are bound to get a hotter flame as basically you are burning a mixed gas - just my thought though

[@Jamesvandaele]

@@ThinkingandTinkering yeah, I used it for platinum and silver, I would use it for melting just the surface of silver plates, then making rings out of them.

[@johanrheeder1640]

water burning and after the flame has burned the only byproduct is clean water

[@colouroboros9993]

never change!

[@ThinkingandTinkering]

lol - cheers

[@johanrheeder1640]

you will find more if you search "brown's gas" i think

[@lorenbush8876]

If that's all it will do it's worthless for jewelers, surely you are doing something wrong or the company that made those was ripping people off.

[@jamest.5001]

That looks just like my cheap mig welder!

cool
