Aluminum Casting with UPS Transformer - No Induction Heater 

Thank you.

Welcome aboard ! 😀

@@MrElectron All aboard the Darwin Express! End destination, your very own Darwin Award. Thanks for playing.

You are welcome. Glad you like it! 😀

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.

Thanks ! Anything that gives 4 to 7v output voltage and continuous current supply of 120A or more would do the job.

Any idea to reduct surface tension on aluminum ?

@@ValeryDjondo remove slag before casting :) and get it hot enough.

You are welcome 😊

Thanks !! Sure. Get a step down transformer that can convert your 220v to 110v AC or make one yourself. It will be fun 👉 ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-gNBdHdp9v5E.htmlsi=dQiQUAYQllGuXtyP

The fun part is melting crap

Yep

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 !

Sure

Thanks 😊! Sad indeed.

I think that in these countries, they just make something like this and throw a wire over the transmission line running next to their house.

What is the output voltage of a welding transformer

24V and up to 140-160A

@@MrElectron 200A

you can also use microwave transformers which are a bit bigger

Not right now but may be after 2 or 3 months.

Okay Sir @@MrElectron

I have 15 more 😀😀😀. Planning something big a future project.

@@MrElectron I have only one from old 24v ups 😅 I'm trying my idea project... Ok good luck bro I'm waiting 😁

@@MrElectron MrElectron ,12v and 24 ups transformers are different or same? Please tell me

@@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..

Plasma channel has already made some good projects on that.

Thanks 😊 ! No you will have to rewind the microwave transformer and then only will it work

@@MrElectron Thanks...!!!

Thanks for the pointer !

Its aluminum. Lead is heavy and soft

I'll try that. Although it seems a little dangerous because of the high voltage.Thick rubber gloves are must in that case.Thanks 😊

It's aluminum and not lead. Lead is much heavier and more soft.

Thanks

I thought that too but there was another way to achieve that by adding a 2kw dimmer circuit to the primary so i did that.

@@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.

@@MrElectron yeah, makes sense. It's still possible to combine the two, though ;-)

Yes, it's definitely possible 😊

It's aluminum and not lead. Lead is much heavier and more soft.

Microwave transformer 20amps

It's all stated at the end of the video. Seems like you skipped it 07:28 & 08:10
