Congrats bro!! I just saw your video from 2017 and thought I'd see if you had any new ones, the design looks really clean now! Improved loads! Can't wait to see what else you do 👍
Zion Sky Hey dood thanks for the comment. If you are on fb I can add you to the group ‘Benchtop Induction Furnace’. I post more frequent stuff there. 👍
tbh it was a fascinating project but if you want a way easier solution then buy a 15kw LH15a from china. £500 and bullet proof. pokey too. i have one now and i can pour 3kgs of copper or iron
Having trudged up that lengthy learning curve my honest advice is buy one of the cheap blue and white ones from eBay. They call them 15kw,25kw and 60kw. I have a 15kw that draws a maximum of 30A at 240v which is not anything like 15kw. Nonetheless they are pretty bullet proof and very suitable for small scale castings. Even if you know all about high frequency power electronics and have a sound circuit, the cost is considerable. I bought mine for £550 which is less than I spent on mosfets and capacitors for my homemade version, which was nothing like as powerful. Hey ho. Cheers
@@laurentiurizac5766 total guess would be looking at sensible 10kg iron pour Look at the Chinese blue and white induction units. Cheap cheerful and bullet proof
@@laurentiurizac5766 im afraid that once you have assembled a practical functional induction melter you will probably be looking at more than a chinese one. true the circuit is very simple (images.app.goo.gl/VD3XaWP4vciYfXjg7) but i found the mosfets died alot (i killed about 50 over the course of the project and at £2.50 each. the power supply was a 10A variac (£130), big transformer from an arc welder (used £50), a massive bridge rectifier (£20), various meters to manage that lot (£30), circuit cooling (machined ali blocks with copper lids £25), chokes (£15-£80 depending on what works), Capacitors (i went through lots of versions and probably spent about £200 on assembling these), protection circuit (£50 and didnt work brilliantly). and then there is the time, and the extras, and the mistakes and the compromises and at the end i still only had a tiny machine that was not really much use as a metal casting tool. I bought the chinese one and it has cost less and works 100% of the time and has 10 times the capacity. hope this helps.
Yeah well it was a hot day! As far as diy melting goes, this is very civilised. No picking the crucible up, no flame, no noise, no fumes and minimal effort to pour

@@itanc1 Hi . I can't find the group on facebook
Lele Armi send a fb friend request to Tancred ingram and I’ll add you in. It’s a private group. 👍

@@itanc1 i don't like facebook. you have no way to explain the realization of an induction furnace with low energy consumption?
Great work!
MLW thanks dood!!
Boom indeed well done bro 👍 be nice to know how to build one maybe a slightly larger one 😁

Very nice
it took 4.5 hours to melt that ?
Yep. It’s only 1.5 - 2kw
@@itanc1 u used 60 V or 30?
@@itanc1 30 ?
55v. 50A. Here is the schematic. ua-cam.com/users/shortsa0nPGjKM0xw?si=TC-nLqTJIxwv_be5
can I make a bigger one?

@@itanc1 i have 3 phase , 380 v , 22 kw , how much could i melt with that

@@itanc1 its not rlly that cheap, could u give me the schematic diagram for your induction heater?

Interesting, subscribed! If you want more subs, feel free to embed your video on our homemade tools forum; looks like you're one of us :-)
safety last I guess
