Diangongbang’s 13-second sales pitch (same script as w113): a handheld rechargeable spot welder that welds nickel strip onto batteries / stainless steel very solidly, welding power and time adjustable, charges from a phone charger; comment: an H1 owner says the H2 upgrades the screen and features, more professional
No need to ask for help or use a soldering iron for battery welding; a handheld rechargeable spot welder that welds nickel strip onto batteries and stainless steel, very solid; welding power and welding time both adjustable; charges from a phone charger, really convenient to use. Screen shows 4ms, T 21℃. Comment: thumbs up for the AWithZ handheld welder, bought the H1 before, this H2 upgrades the screen and features, looks more premium and professional.
A repairman's 31-second revelation: after decades of soldering 18650s with an iron, only today did he learn there's a handheld spot welder, far better than a soldering iron; press down, fire, give it a tug and it's rock solid (screen shows gear 90)
Appliance repairer Xiao Yi: soldered 18650 cells with a soldering iron for decades, and only today learned there's a handheld spot welder, much better than a soldering iron; here's a test for everyone; press down, spot weld; done, give it a tug, very solid. Comments are all asking the price; someone says it runs out of charge after a few welds; requests for a full-length video.
Unboxing a ¥100-class handheld spot welder: 11 gears, manual / auto, Type-C charging; on gear 8 auto, welds on both 18650 and coin cells can’t be torn off, recommended for home use
Unboxing a ¥100-class mini handheld spot welder: in the box are the welding pen, a charging cable, a sheet of sandpaper and a pack of nickel strip. The body has 11 gears, a manual / auto indicator and a battery indicator; long-press to power on, button to change gear, long-press to switch mode; Type-C charging, arrived fully charged. Tested on an 18650 and a coin cell (which a soldering iron basically can’t solder): gear 8 auto mode, two welds first, then six, pulled and torn and they won’t come off — the strip tears instead; welds on the coin cell are round and solid. Verdict: for the modest volume of home use, worth recommending. In the comments the creator replies the strip thickness it can weld is 0.2; a top comment questions the built-in battery’s lifespan, saying a supercapacitor model would be better.
