I'll post pictures in the evening after work. It was very easy and simple to build. Here are the list of parts I used.

1. Microwave Oven Transformer.
2. 2 yards of 16mm cable (multiple core or earth wire)
3. 4mm single core (using as my electrodes)
4. Microstroke switch
5. Wires

This morning, I woke up by 3am to test the weld on some cells and it was really good. I'll be using it for future battery pack projects and it will make my job really easy (goodbye to soldering of battery packs).

I can't wait to see it

can't wait to learn

Oya, let's see.
Planning on making one also, though with microcontroller and MOSFET.

Let see the weld too.

...

I am planning to use old stabiliser casing to make an enclosure for it. Though I'm in no hurry for now because of competing demand for funds. Meanwhile, I'll use it as it is though I acknowledge that having an enclosure for it will make it safe and good looking, besides, they will be reduced risk of electric shock.

This is the video of the weld

I'm thinking of getting a control board, even a. Welding electrode from Aliexpress for it. But I don't think I really need it now, besides, I can use the money for other purposes for now.

For now, as I have saved myself from the stress of soldering cells to make packs, I'll rather spend the money on battery capacity tester, purchase of more nickel strip etc.

My needs are much for now.

that's just it, so many things to buy. And one will still have to order from far away. Few that are selling parts here in 9ja will rip off somebody.
I have electrode though, I just need a handfull of powerful MOSFET to make it.
Soldering isn't good for those cells, unless you'll be very fast.

The result is good.
Maybe I'll get the transformer 1day

I have been soldering all my packs since and it's not funny. That's after I have finished salvaging the cells from dead laptop battery. It's not funny at all.

Hello sir i have a very powerful all in one tester/charger and ballancer and it can also charge all type of battery inluding lifepo4 max charge current of 5Ah and can charge 4 6s at same time
I will post pix of it latter

Same here, i have wrist sprain from the last one I did. Will surely give this a try

No be small thing.

Nice one op, you save a lot of us some trouble.

Pls how do u remove d secondary coil because I wasted one transformer in dat process now

I took mine to these people that make aluminum windows and doors. I should him the cool to remove. So he sawed the coil, then use hammer with a rod (chisel etc, can't remember) hammer it out.

He sawed it off first. Then hammered it out.

ok thanks

Can someone guide me on how to build my own lithium battery please. I am finding it hard to wrap my head round the process, despite watching the videos

Hi, how can I connect to you... The video you posted is not available.
Do you wire the secondary wire (16mm) with the wire shell or you pill the shell off, and also instead of 2 turns which give 2.2v, can it be turn up to 6 or 9 to make around 6.6v or 9.9v to increase the welding capacity, that it to be able to weld pure nickel of 0. 2mm or 0.25mm.
Also can one add screen to set the output welding power and others.... Please video will be appreciated.
Thank

Why not just buy a spot welder machine

Did you eventually build this? Or there are cheap, available off the shelf ones I can pick.
