The attached images are using a 16340 cell with the included 0.1mm Nickel Strip at maximum power (Gear 8.0), it’s just about acceptable for this. Having pulled the strip off you can see the welds have fused with the battery terminal surface.I tried 0.15mm strip and the welds do not hold properly. 0.2mm and it doesn’t generate enough heat to weld at all.Other points:* The Included instructions are awful, they are translated so poorly that large sections of them are complete nonsensical gibberish. The main point to note is it’s a resistance welder, so probe pressure is key when welding. Lots of helpful online video tutorials are available.* The included strip is proper nickel strip (Tested by both disc cutting and 24hr salt bath).* The welder case body is aluminium and nicely constructed. The leads are also well made given the price point of the set.* The Power-bank function is basic, USB-A output only, tested and can supply a maximum of 7.5W (BC1.2).* No physical power off switch so the device drains down even when not in use. It is recommended to recharge the device every 3 months otherwise the Li-ion low voltage cut-off may kick-in and the device no longer function.Conclusion:If you are looking to weld battery strip carrying no more than 3-5A (Acceptable current for 7mm x 0.1mm strip) then this is probably an okay choice. For anything else I personally think you will need something with more power.
