11-Setting Spot Welder | Handheld Tool for 18650 Batteries & 0.3mm Nickel Strips

The FS01 11 Gears Adjustable Spot Welder is a handheld tool engineered for reliable, high-current spot welding of nickel strips onto 18650 lithium batteries. Its 11-gear power adjustment allows precise control for welding up to 0.3mm thick nickel belts, ensuring strong, consistent welds without damaging sensitive battery cells. Features and Benefits - 11 Adjustable Power Gears - Fine-tune the welding current from low to high, providing optimal energy for different nickel strip thicknesses and ensuring clean, non-penetrating welds. - Weldable 0.3mm Nickel Belt - The robust power output creates secure, low-resistance connections on thicker nickel strips, essential for building high-capacity battery packs. - Handheld & Portable Design - Operate freely without being tethered to a bulky bench unit, offering superior maneuverability for assembling packs in various positions. - Professional Spot Welding Performance - Delivers the concentrated, instantaneous heat required for proper battery tab welding, far superior to soldering for safety and joint integrity. - Durable Construction - Built as a reliable, budget-friendly professional tool, offering excellent value and quality construction suitable for regular DIY and professional use. Applications - 18650 Battery Pack Assembly - Construct custom power banks, e-bike batteries, solar storage systems, and other lithium-ion battery packs with series and parallel connections. - Battery Repair and Maintenance - Replace faulty cells or nickel strips in existing battery packs for devices like laptops, power tools, and emergency lights. - DIY Electronics and Prototyping - Create secure electrical connections for robotics, custom LED arrays, and other projects requiring robust, high-current joints. - Small-Scale Manufacturing - Ideal for workshops and small businesses producing limited runs of battery-powered products or performing in-house pack assembly.
