Isn't it incredibly dangerous to disassemble microwaves?
The magnetron can have insulators made of a toxic substance that can be dangerous as a dust. This guy is just using the transformer for it's convenient laminates and primary winding - probably could have used a similar transformer with suitable current handling capacity but dead microwave ovens are fairly common. I have 3

These MOT based spot welders transfer far more heat to cells than capacitive discharge welders. This can result in the damage to heat sensitive components inside the cells which is the same reason that soldering isn't recommended for lithium cells. To get around those issues, I built a capacitive discharge spot welder for tabbing lithium ion cells a couple years ago: http://robruark.com/projects/welder/welder.html
Electroboom would too.
In the end of the video he lists off the number of things he did that were fancier than necessary. One of them was the use of an Arduino for the pulse duration and switching. I found myself reflexively commenting, "It's called a 555 timer." I'm confident that the same function could be more minimally implemented with a 555 timer and maybe a couple other supporting chips. But he's probably getting more consistent cont…

Having digital timer settings would be tricky without a processor, I imagine.

What are the dangers here? What happens if that thin insulation between the copper bars breaks? Can the current jump to you if you use this bare handed?
Well it's only 2 volts. So nothing will happen. Unless your hand is all sweaty maybe. Then maybe you'll feel it. I wouldn't worry.

I believe it's the amps you need to worry about; "amps kill."
I believe it takes about 1 amp to kill a person.
This thing is outputting somewhere around 55 amps (if I remember right).
Earlier quoted context omitted.

uh... wut I believe it's the amps you need to worry about; "amps kill." I believe it takes about 1 amp to kill a person. This thing is outputting somewhere around 55 amps (if I remember right).
