Details

This product is developed for precision welding of cylindrical battery negative terminals, specifically integrated into automated cylindrical battery production lines. Designed for high-consistency joining, the CAN-WEL21-010KST spot welding machine ensures reliable electrical connections with minimal thermal distortion, supporting the manufacture of lithium-ion cells requiring stable weld quality. Its compact form factor allows seamless integration into existing assembly systems, accommodating standard cylindrical cell geometries. Typical applications include 18650, 21700, and 26650 cell assembly processes where consistent spot welds are critical for cell performance and safety. The machine's welding parameters are optimized for nickel-plated steel or pure nickel tabs commonly used in battery pack construction, providing a balance of weld strength and energy efficiency. No specific performance figures are available from the supplied data, but the design aligns with industrial requirements for repeatable, low-resistance welds in high-throughput environments.
