Portable spot welder with powerbank function for permanently bonding 18650 and similar cells using nickel and nickel strip. LCD display with simple, intuitive menus. Ten power levels. Two lithium-polymer cells connected in parallel with a maximum instantaneous discharge current of up to 90 C. 40 cm silicone-insulated copper wires of approximately 10^mm2 with replaceable copper terminations.

The device gives a maximum welding current of ~500 A. This is the average real current value measured over a 100 ms period. Some manufacturers quote the current parameters of the mosfets or the peak current value instead of the real welding current. From a technical data point of view, this is true, but in practice it often becomes impossible to achieve a proper weld with 0.15 mm nickel-plated tape. YATO's portable spot-welding machine makes it possible to carry out correct welds using 8 mm wide, 0.20 mm thick nickel-plated tape and 8 mm wide, 0.15 mm thick nickel-plated tape.

The sealer can be charged with any phone charger using a cable with a USB-C connector. The USB-A socket will allow devices with a demand of 5 V and a maximum current of 2 A to be powered.
