On the left, from the second-hand market (Xianyu), ¥180 and no charger, you sort your own; on the right, from the Douyin store, ¥500, and there’s a difference: this lead (Xianyu machine) is thinner than my life, pitiful, and the tips aren’t even one piece; (the AWithZ’s) are so rounded, they say it handles 0.4 nickel strip, seriously strong, and it has a button, aluminium-alloy shell (nameplate UF20B 6.0V / 1750A / 10.5kW / 100–240V, Juequi Technology); I can’t really read power ratings, I just buy the pricey one, the pricey one’s stronger, that one’s low power. The Xianyu machine throws sparks on every weld; this one is different, the pen has a switch underneath so you don’t need to hold anything, just go bang-bang-bang rapid-fire, so much fun, burnt the tablecloth, the genuine AWithZ; and this isn’t even the top gear, it’s on 31, 99 is harsher; big thumbs-up for that switch, so convenient. Switch to gear 99 and weld a utility-knife blade: whoa, a stainless blade this thick nearly welded on, welded through, how’s that for strong; don’t recommend welding like this, too hard on the machine; blew right through the blade. 613 comments: the bought one wins, AWithZ is reliable (is this brand that big a deal?); Duokerui and AWithZ are about the same, which is stronger (they say they may well be the same company); bought a P120 for ¥2600 on promotion, ribbon cable loose, returned, don’t trust the QC (let me try one too); good enough, fairly strong, easy to use (it really is strong, the pen button is super handy, the lead’s just short); at ¥180 back then there wasn’t even a pen, better to buy Kekaike; both of the desk-top ones are toys (how big does it have to be to not be a toy); a hand-built microwave-transformer one has far more current and sits gathering dust; a ¥400 one off Xianyu does 0.4 aluminium-nickel easily; supercapacitor + LTO builds are cheap and powerful.

Sharing money-saving experience from hand-building lithium packs so beginners spend as little as possible. The three-piece kit: the welder is essential, the internal-resistance meter is optional, the load tester is optional — a beginner only needs a welder, skip the other two for now; early on, only build small packs and order straight from the cell brand’s official channels (EVE official site / Tmall / Alibaba; the page shows 18650 3.6V 3200mAh / 2850mAh etc.), which basically needs no testing — with a welder you can build right away; think about instruments later when going to big capacity. Key point — which welder suits a beginner: buy the most expensive one you can accept within your budget, and go for a big brand as far as possible; this is the third welder I’ve bought (AWithZ); one feature is very beginner-friendly: the pen sits on the cell for ages and nothing happens, because the manual weld button hasn’t been pressed — press it and it welds instantly, the semi-auto mode; beginners often mis-place the spot or set the nickel tab crooked, and if the pen welds the moment it touches, the cell is ruined, so a semi-auto button is best to have; there is also a repeat-pulse mode that welds the same spot repeatedly, suited to copper sheet that needs more power — hold the pen steady and it fires up to 3 welds in quick succession. Mine is the AWithZ U3 Pro: pure nickel 0.2mm MAX, and it also does steel and copper sheet (copper 0.1 MAX; nickel-plated / steel / iron 0.35 MAX); nameplate U3 battery spot welder, 4.2V MAX, Type-C 5V/2.1A, USB 5V/2.4A, 11000mAh 40.7Wh, Juequi Technology; plenty for a beginner. Consumables: glass-fiber tape, heat-shrink film, fish paper. A special note on cells: this is the positive, this side is negative — many people don’t know the whole can is negative; open one up and everything except the positive is negative, so positive insulation is critical, always use positive fish paper. Non-essential accessories aren’t covered; get the three-piece kit straight and you save a lot. Comments: asking for the EVE official link (search results are all ads) (2); lend me the welder for two spots nearby; can UV glue join them; what battery for a 24-set net-hauling boat; a mis-weld ruins the cell? can’t you pull it off and re-weld?
