So for a long time, I was debaiting wether or not to make/buy a spot welder.
I'm planning to build maybe 5-10 packs of different sizes, not too big (max. 6s4p).

I first tought of building my own spotwelder using an old microwave transformer and arduino to control. I'm not really sure if it's worth the danger if a 50$ device can do the same thing.
I heard about the AwithZ devices and that they're apparently great, but at 150$ I can't really justify the price as it wouldn't be worth it to build my own packs.

I'd be glad to hear you're thoughts, maybe I'm just not thinking it through, anyways thanks in advance :)
