AWithZ portable Li-ion spot welder — welding results in tomorrow’s video

The Village’s Only Primary-Schooler unboxes the AWithZ portable welder (UK1) while minding the shop: the one at home is too heavy to carry, so he bought a small one; two layers in the box — certificate, foot switch + silicone-lead welding pen, trigger switch, main unit ‘really quite light’; powers on to look at the settings, welding test waits until the cells arrive; pinned reply: it needs a full charge and the top gear to weld 0.15

A few more tool batteries (Dongcheng 20V 4.0Ah) need new cells today, all dead; sometimes he minds the shop and does his own stuff on the side; the spot welder at home is too heavy to carry around, so he got a small portable one, quite light; just arrived, open it up: there’s another layer inside; certificate; foot switch and welding pen, the pen is decent, silicone lead; this is a trigger switch; the welder itself really is quite light, easy to carry; power on, settings menu, not bad; welding test later once the cells are brought over. Comments (11): the small AWithZ I bought last time welded so badly I returned it → creator: it needs a full charge and the top gear to weld 0.15; what battery is inside, what price; battery-based or capacitor; how much; tear it down; I just solder.
