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 mm 2 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. • max welding current 500 A • input current: 1-1. 5 A • output current: 2 A • input voltage: 5 V • output voltage: 5 V • Operating temperature range: 0~35 °C • battery type: Li-Po • battery voltage: 4. 2 V • battery capacity: 6300 m Ah • dimensions: 148 x 86 x 30 mm • display type: LCD • weight: 0. 32 kg kit contents: • welding cable 2 pcs • welding pin 4 pcs • charging cable
