    If you do decide to use this for small-scale welding, you might consider adding a third bubbler bottle, and filling it with methanol. The flame as it is now is neutral to slightly oxidizing, which makes for a rough weld, but with the addition of a bit of methanol vapor, the flame is reducing, and reduces metal oxides back to metal as fast as they form. You can also add boric acid to the methanol, and the resulting methyl borate is volatile enough to be carried over with the methanol, leaving a protective flux layer as it burns.

    @@NICEFINENEWROBOT This isn't a thing that happens. There's only a tiny bit of oxygen in the system at any one time, and no matter how much fuel you add, it doesn't become more explosive. In fact, it becomes a lot less explosive. The stoichiometric mix burns hottest and ignites easiest too, so adding extra fuel makes the flame a bit cooler, less fast burning, and less likely to explode. For happy fun insurance facts, you might want to check your rates: an oxyhydrogen jeweler's torch with methanol bubbler is cheaper to insure in most places than one that takes tanked gasses, specifically because of the smaller chance of explosion and the small quantity of explosive gas present at any one time.

    @@andrewtinker7537 A bottle filled with volatile fuel were gas with a high content of oxygen is bubbled thorough it sounds like a recipe for disaster if there is a flash back and the bottle breaks. And yes there is more oxygen and fuel in such bottle than if it was simply air what is being bubbled so definitely more dangerous specially because methanol has significant explosion limit of 7.3 to 36 %. The risk is not so much huge explosion that will kill you but a fire if the bottle breaks when it explodes and sprays everywhere burning fuel. Its safer to simply inject gas from a propane bottle into the stream with a needle valve to control oxygen balance than have a difficult to control bubbler were the slightest change in ambient temperature throws off your adjusted oxygen balance and that has the risk of exploding.

    I've reacquired most of the hearing in one of my ears, after a flashback blew up one of my plastic bottle bubblers on a similar setup I made several years ago. I stopped messing with hho, but decided the electrolysis chamber design that uses high count silk sheets to seperate the H and O to seperate chambers is a better idea. Had I been wearing hearing protection I'd probably have a large hydrogen casting torch by now. Damaging my hearing sent me down another interesting rabbit hole, learning about the inner ear (the cochlea) that processes a particular range of our hearing. I learned military doctors have used a few vitamins to successfully treat partial hearing loss in many of their patients and took those vitamins for about a year. Even so, crickets still sound like a poor commodore 64 impression at times.

    The old Browns Gas generators used a flame arrester bottle full of methanol to act both as a flame arrestor and as a means of making the mixture slightly rich (reducing). Another trick was to add either borax to the liquid to add a trace amount of flux. The old Browns Gas arrester was a heavy stainless steel cylinder with a wide screw on lid and welded in fittings.

It makes a terrifying screaming sound while slowly melting your entire torch and it's handle, burning down to the oxygen and acetylene gas lines. That's why multiple flashback arrestors on a oxy-acetylene is a must have, or things can quickly go kaboom. This is what we call a sustained flashback, or sustained backfire.

    There are videos showing 30-40 LPM HHO production on youtube. You just need to stack up enough plates and run a current through them. You want high current but low voltage per plate (2-2.5V). 20A at 240V using ~100 plates will produce several liters of gas per minute. An oxy-propane glassblowing torch usually uses about 5-12 liters of oxygen per minute.

    I had a flashback incident many moons ago when playing around with a hydrogen system when I was young and dumb.. I didn't have a water bottle in the line, and the end of the outlet hose which would normally have soapy water bubbles over it, didn't at that moment, and the gas, which is of course invisible, flowed out to a standing candle a foot or 2 across the table.. The gas caught, the flame raced back to the hose, and into my 3 litre capacity generator vessel (a large glass coffee jar) igniting the top 2 inches of gas, and blowing the entire thing apart.. The volume of the sound was incredible. The lid of the jar, also glass, was lodged in the ceiling plaster, and 2 and a half litres of hot, salty (bicarb soda) water was almost instantly distributed quite evenly around my dining room, and easily masked the million or so shards of glass, many of which I was still finding, months later, with my bare feet.. This was 12 or 13 years ago, and is probably the main reason I have very annoying tinnitus now.. I would not recommend repeating this.. As for screaming like a little girl.. dude, there was no time to scream.

    Hey. Just an idea for an additional experiment using the Oxy Hydrogen generator. Years ago I saw a video out of Germany that strongly proclaimed that the gas going through the water in the bubblers did SOMETHING to the water that dramatically improved it's ability to nourish plants. He stated the plants he watered with the bubbler water grew at 3-4 times faster than the same plants given regular water. I thought that since you already have the torch, you might be able to get some interesting "experiment" content pretty easily just by trying it out. :) I realize that at one year after you posted this video you might not see this comment , but I figured I'd try anyway!

    Just a quick warning: stainless steel is not a particularly safe anode material for anything you plan to use more than a few times. The chromium in the stainless will produce hexavalent chromate (extremely toxic and difficult to dispose of) and turn the electrolyte yellow over time. It’s a slow process but it does happen. Some cheap alternatives are graphite (will slowly break off graphene sheets over time but it’s not fast nor a problem really) or nickel plated copper. The best is platinum plated titanium (which you can buy on Amazon). It lasts the longest and gives the reaction a nice catalytic kick as a bonus. Great project regardless, and video!

    Really neat! An easy improvement to the apparatus would be a finger valve on the gas line to the needle. That way you wouldn't have to extinguish the flame with the paper towel to stop the gas flow. Alternatively, a one-way valve would work as once the pressure fell if the power was lost, the fuel would be cut off. I'd also be really interested to see if a Tesla valve could be used as a spark arrester. Since the gas flow is so fast (and thus the pressure), a Tesla valve should really slam the breaks on the reaction.

    This seems like a good method of making silicon oxycarbide from precursor polymers, meaning you'd be able to do a makeshift additive 3d printing of SiOC parts- useful if you need something structurally complex and very resistant to heat, or if you want a scratch resistant coating on a rough surface. All you need is dimethicone, which is very cheap.

    Reminds me of the dangers that come with oxyacetylene torch welding. Very interesting! I wonder if it would useful for minute detailing in glass work.

    I know H2O as hydrogen and oxygen since my childhood but never thought this way of mixing them. Thumbs Up.

    I've always been fascinated by electrolysis ever since a demo of it at space camp. This idea is absolutely fascinating to me and I very much want to try it, but your warning has sufficiently deterred me from building a setup like this. Perhaps I will explore a H2 and O2 generator that mixes right at the tip and has no danger of explosion.

    These torches sometimes are bubbled through additives that consume some of the oxygen in the mix. This results in a hydrogen rich reducing flame, which is an even better for preventing weld oxidation than a shielding gas.

    Why are these called reducing flames? I realize its the chemical sense of reducing, but whats the significance of a fuel-rich flame being reducing? Or is it just because its the opposite of oxidizing and the opposite of being fuel rich is being oxygen rich?

    @@chrstfer2452 Hydrogen itself is a reducing gas - it can bind with oxides on a metal’s surface and convert the oxide back into metal (generally an endothermic reaction, but welding and other physical metallurgy processes) have plenty of heat available to enable that reaction. Just any fuel being supplied won’t necessarily cause the same reaction, as something like acetylene won’t want to bind with oxides anyways.
