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

DIY tools | A portable spot welder — niche but professional. I’ve been building a solar-lamp project lately and need to weld lithium packs for storage. I’d always used a soldering iron, but soldering lithium cells is slow and a safety risk, so I got a portable spot welder (AWithZ U3) and it works well. Compared with an iron, pulse spot welding avoids cold joints, the nickel strip sits tight, no hot iron is needed so there’s less risk of damaging the cell, and it’s very fast — one weld in 3 seconds, ideal for batch work. Spot welding was new to me, but it really is better suited to battery mods than conventional soldering
