Features Versatile Spot Welding Welder Designed for precision, this welder performs both nickel-nickel welding and pure nickel spot welding to the aluminum electrode of an iron lithium power battery. It's suitable for welding pure nickel and nickel-plated sheets of ternary lithium batteries, ensuring high reliability in your projects. High Efficiency Equipped with an S-75A split spot welding pen featuring an ultra-low internal resistance process, this tool guarantees maximum efficiency. With an internal resistance lower than 0.46mΩ, it surpasses most 35mm² non-professional soldering pens in the industry. High Energy Double Pulse Welding Achieve breakthroughs in performance and efficiency with the ability to weld pure nickel directly to the aluminum electrode of a lithium iron phosphate battery. Dual Function Welding Tools Includes a flexible and unobstructed spot welding pen, providing a hassle-free welding experience for all your needs. Excellent Power Output As a high-power welding machine with a 19.8KW 3500A output, it seamlessly handles spot welding of 0.2mm pure nickel to the aluminum electrode.
