This versatile portable spot welder is designed for reliable, permanent bonding of 18650 batteries and similar cells using nickel and nickel strip. Equipped with an intuitive LCD display and simple menus, this welder offers ten adjustable power levels for precise welding control.
Built with dual lithium-polymer cells connected in parallel, the device achieves a powerful, instantaneous discharge current of up to 90 C. It features durable 40 cm silicone-insulated copper wires (approx. 10mm²) with replaceable copper terminations to ensure optimal performance and longevity.
Delivering a maximum welding current of approximately 500 A (measured over a 100 ms period), this welder enables consistent welds on 8 mm wide, 0.20 mm thick nickel-plated tape, as well as 8 mm wide, 0.15 mm thick nickel-plated tape—unlike other models that may not deliver true welding current levels for high-quality results.
For added convenience, this welder includes a power bank function. Charge it easily via any phone charger with a USB-C cable, and use the USB-A port to power 5 V devices with up to 2 A current. Perfect for portability, precision, and versatility in any project.
