Over 20 years ago, I was doing patent research, and I ran across a ca.1910 US patent (yes, THAT old) for an alloy and its method of preparation that involved an electrically heated graphite crucible. The patent was old enough that passing current directly through the crucible wall was actually the heating method (predated common use of induction heating). The patent contained a diagram of the crucible, which was supposed to be novel, and the alloy composition accounted for a certain amount of the crucible wall (intentionally) dissolving into the final alloy on each new melt. I'd never seen a similar process used until this video. As it was not a part of common industry practice today, I assumed there was some reason it fell out of favor.
I like your tile connection crucible idea, but instead of handling transformers, couldn’t you just use one of those inexpensive stick welders from Amazon and connect the high amperage output wires directly to the tile connector?
those sharp points in the contacts, where also a big risk for arcing :D .... you get rid of them at the end of the video, but was important to highlight the problem 🙂
That was not the reason because of which i removed it. The bigger size of the contacts increased the current flow, so to reduce that current, i shortened them.
There was only 7V on the transformer output. No chance of arcing between the terminals. Having the contacts just flat with a small gap in between would probably have been the best for any size crucible.
Get a transformer out of an old transformer arc welder. I haven't seen one do less than 100 amps and even relatively cheap units often do 200amps. Transformer welders usually have multiple Taps in the windings or a variable distance between the primary and secondary windings allowing for much more control. You should also try using an Arc to melt the metal. Have the crucible + and a graphite rod - and short the rod directly to the metal in the crucible so more of the heat goes into the actual metal and not everything else.
You should try a saturated inductor like what they use for a welder. An old large Transformer you run your line through one side of the Transformer the higher current side and then the lower current side you run around 24 V DC on a small little potentiometer. The more DC that saturates the Transformer the less electrons can flow through which in turn creates resistance
Seems like I remember reading that commercial aluminum smelting is done using carbon electrodes dipped into the melt instead of heating the crucible itself. Could use your bushes to touch the aluminum and heat it directly.
great vids very informative i have a older honda 4500 watt portable gas generator it is 220 0nly no 115 or 120 receptacals is the any way to run 115 or 120 of it i dont want to fry any of my 115 tools
Thanks !! Sure. Get a step down transformer that can convert your 220v to 110v AC or make one yourself. It will be fun 👉 ruclips.net/video/gNBdHdp9v5E/видео.htmlsi=dQiQUAYQllGuXtyP
You can slow down the speed of the engine to get 120 voltage or just get a 220 to 110 step down transformer to run your 110 equipment by just plugging in the 220 input side of the transformer into the generator output socket and then take the 110 voltage from the transformer output side which is 110 voltage...that is easier that slowing down the gasoline engine to obtain 110 voltage output which i have done that on my 48 feet ice fishing boat and used mu generator fir a number of years without any problems my generator was a poratable 220 voltage gasoline generator 2000 watts .
How much current is this drawing from the outlet / primary? Is this 120v or 220v, what are the transformer ratings? Maybe tell people to not breath the fumes too, some of the plating like zinc and cadmium can be DEADLY.

I wonder if you use two carbon rods dipped in aluminum dust which is in a ceramic crucible, if the aluminum will melt, then add borax, and refine more aluminum from the borax?
Please take care! Floor tiles do not handle the stress from uneven heat distribution. I have had plenty shatter on me due to concentrated heat. Because they are serving as the base for the crucible it could be an serious accident waiting to happen if the tile shatters, tipping the crucible and then causing the molten metal to spill.

And it looks more like zinc or something. Aluminium is more like water when fluid and also didnt melt, if the crucible is realy red. May be i am wrong, but didnt look to me, like it's aluminum. May be an alloy that looks somehow other than what i know.. i dont know. Away from that: Try not to use a small contact gap for heating the crucible. I would think a longer gap should give a bigger resistant to more fit the voltage and heat more area, so the crucible wont be cooled so much because of the area, which isnt heated by current. I would try to connect the (first round) crucible one contact at the bottom and one at the top in a ring shape, so to make a big surface contact and also heating the hole crucible by current. I would be very curious, if that would work better... Rewireing like you said would be also an idea.. but that work :) .. I had this idea in mind for a very long time and i am so happy, you done it. just to see, if it will work and under which conditions. Go on, good work !
You'd have to modify the secondary windings for a few turns of a thick gauge wire. A standard MOT would only output a couple of amps at 2000V which wouldn't melt much but would kill you instantly if you touched it.
I liked it a lot...!!! Can I use microwave-oven-transformators for the job (without re-winding them), or are their primary/secondary-windings not matching the requirements ??? Thanks
@@DonnieLuve yeah thanks for the reply😊... According to my opinion, maybe the secondary winding of the ups transformer is different between 12v and 24v ups transformer
@@DonnieLuve wow that sounds cool yeah... But if the transformer ferrite core or steel core , it's small and we give the same turns of copper, maybe the output will changes.. I've not study much about transformers in high school, I'll try to study more..
At a metal melting pot increase voltage to 480 volts ac between carbon electrodes separated and hung above pot. Fill pot with metal you wish to melt. wear welding shield and gloves. Very slowly lower electrodes toward metal in pot. Voltage on between electrodes while lowering. When arc is born, slowly back out electrodes a little. Fan suck hose above melt to outside. This is effective and proven technology. The only heat is arc. 50 amps max. Higher voltage stops wire heat up effect you are finding problematic. I saw this in operation for real. 😮😮😮 Three phase 480volts three electrodes. A Large truck alternator with diodes taken out. Feed ABC phases to ABC ELECTRODES. ONE PHASE ONE ELECTRODE. DRIVE ALTERNATOR WITH SMALL DIESEL RUNNING ON WASTE OIL FROM GASOLINE ENGINE OIL CHANGE. GOOD LUCK SON AND HAVE FUN😂
@@MrElectron its work at lower voltages, direct ac from 3 microwave oven, no connection current 60V, i was able to arc 2 carbon electrode in order to melt aluminum oxide ~2200degree Celsius, anyway probably too much current for r20 battery carbon rod coz it got destroyed in minutes, probably because exceed 3000 degree
Your secondary voltage is much too high, most of the power and heat leaves through the wires and transformers. You should connect your primaries in series (2-3 each) and the secondaries in parallel. The voltage will be lower and the current essentially the same, leading to less energy wasted there.
@@MrElectron sure but it still wastes energy in the dimmer or, if it's a switching dimmer, alternantes between high current with losses and zero, then delivers less total power. With the transformers in series by 2 or 3, you'd reduce the peak voltage to what you currently observe without heating the core and primary as much. This would also allow you to add even more transformers ;-) BTW, kudos for machining the graphite to make a current conducting crucible, I love the idea!
Actually, what's more important is to limit the overall ouput current to 20A per transformer for which the dimmer is still necessary. I understand that by connecting the primaries in series, i can bring the output voltage down to half and even lesser output amps, but to maintain them at precise 20A , dimmer is still a necessity at the cost of some minor losses.
This transformer made for normal usage in computer, not for permanent shortcut to give 100 Amps. He used 6 pcs transformers but they’ll overheat and smoke shortly…👌
Столько трансформаторов... и столь мизерный результат. Знаете, где ваша ошибка? Ваши трансформаторы дают слишком высокое напряжение и вся их мощность растрачивается на нагрев обмоток. Вы получили бы лучший результат, если бы взяли всего один трансформатор (ну, возможно два), и перемотали бы вторичную обмотку. Оставили бы три-четыре витка, но гораздо более толстым проводом. Можно было использовать тот же который был, но сложить штук по пять проводов. Вот тогда вся мощность пошла бы в тигель. И он был бы ярко красным. А еще практический совет. У кого есть столько трансформаторов от ИБП? Может быть их надо купить? Сварочный инвертор обойдется дешевле. А результат точно такой же.
