Very nice to watch it, thanks for sharing.

I enjoyed this, also I subscribed to your channel.

Good video! Undoubtedly that spot welder is not of any use. I build a few of them and learn a lot. Those welds are not strong enough and the pulse is too long. For your own safety don’t use it on any lithium cells. But the video and the look of it is great!

Thanks for the comment, I had a problem with what you said, but I experimented with the windings on the transformer and now it's okay for me. Did you use 40 amps or 100 amps electronics?

[@Newtonn2]

I used the 100a version. I did three turns with 50mm2 and did not split the cable to put any connectors, also made sure it is as short as possible. You can loose power with the connectors and the length of the cable. Mine can weld 0.15mm on the minimum setting of pulse (1) and at 65% power. But then I cut the cable to put connectors like yours and a more flexible cable that was a bit longer, and that made it unusable. I ended up using an ARC welder transformer instead.

Odličan video, bravo 😎 pametno je što si se baziro na engleski jezik!

[@electro_solar]

Hvala, trudim se prisjetiti engleskog hehe

@@electro_solar samo polako, čim kanal krene iskakat ljudima s tim dolazi sve veći i veći broj subova. Prednost toga je što si izabrao engleski jezik jer tu je puno veća publika, plus kad bude tisuću subova ići će i puno veća zarada od monetizacije! Zato se samo drži engleskog i budi strpljiv. Izbacivaj video 3 puta tjedno radi samog algoritma yt-a! Gledaj svakako da ti video ne bude duži 25-30 minuta. Nadam se da razumiješ što ti želim reći. Lp

@@CroR4g3 Naravno, hvala svakako :D

Uzmi veći presjek kabela za sekundar pa ti niko neće moć reć da je to komad smeća.

[@electro_solar]

Samo nek tipkaju sta god hoce :D

[@tomaszradomski9008]

Yep I must say that your spotwelder is a piece of junk. First of all you did not spotweld that two nickel strips even with 800ms of time when spotwelding must be around 20-60ms. Every 01 on controller is 20ms so 01=20ms 03=60ms 10=200ms. So that machine is useless I'm sorry to say that.

[@electro_solar]

Ok, tnx for comment

[@ivankirola2707]

Make a video in which you made it better
