Do you really have to hand-build a spot welder to hand-build Li-ion packs? Don’t take my detour — see what you make of this one

This lesson is all detail for beginners — the chapter of the hand-built Li-ion course that keeps you from getting blown up, bro! Old hands, now it’s your turn to roast me

0.2 copper straight onto a Jiashikai negative — I’m telling you, don’t try it! It just won’t hold…

Honestly, I haven’t figured this spot welder out — 9.9 gears, and 0.1 nickel strip only needs gear 1.5 to 1.8! I haven’t figured it out and you’re still buying it after me, unbelievable

Back then I was a newborn calf that feared no tiger and nothing ever went wrong; now on the third build I keep ‘blowing it up, bro’ — mainly my own carelessness, but this AWithZ P60F welding pen is longer than the old UF20B one, which gave me two shorts and blackened the pen; if I use it again I’ll wrap it in high-temperature tape, whether it needs cooling or not

Welder at gear 60, welding 0.05 copper + 0.12 nickel-plated steel strip — the results

A follower asked whether the AWithZ UF20B can weld copper stacked directly; I said probably not, he said support says it can with flux. Fine — if you don’t believe me, don’t ask me again, the video is right here, see for yourself. The welder is the AWithZ UF20B from my showcase, upgraded No. 6 welding pen: copper straight on vs copper on a nickel base. Also found some followers haven’t even figured out nickel base layers… mainly I turned the power bank into a 30000mAh one, and it’s a joy

Ep. 178 | The welding pen’s lead blew up on me before, mates. On a viewer’s recommendation, it gets a jacket — feels a lot safer

Never serve low-end customers — deep down they don’t recognise your value
