Versatile Usage Achieve precise and clean spot welds with support for welding iron and stainless steel sheets from 0.05 mm to 0.3 mm. This capability supports a range of small, accurate welds in thin metals. Applicable for Lithium Batteries This spot welder board is designed for spot welding of lithium cylindrical batteries such as 26650, ensuring efficient and accurate results. Large Current Capacity Using 5 MOS tubes and a maximum current of up to 2390 A, it is equipped with 2 brass bars to enhance overcurrent capacity for effective welding. Efficient Welding Principle The welding process is based on current and temperature melting and cooling of foil, ensuring efficient and quick results. Applications and use scenarios Battery pack assembly or maintenance: spot weld lithium cylindrical cells such as 26650 to create compact, reliable battery packs or perform celltocell connections. Thin sheet metal welding: weld iron or stainless steel sheets in the range of 0.05 mm to 0.3 mm for electronics enclosures, chassis, or small metal components. Prototyping and fabrication tasks: perform current foil welding in smallscale projects and repairs where quick, reliable welds are required.
