The EKSW004 automatic single side spot welding machine is engineered for efficient welding of multiple battery cells ranging from 18650 to 32700/32141 sizes. It supports up to 24 series and 12 parallel combinations, totaling 288 batteries in one setup. The machine uses a precise, air-cooled welding head with adjustable pressure knobs to ensure balanced welding and to prevent fire hazards or false welding.

Designed with durability and ease of use in mind, it includes a servo screw module for stable, low-noise spot welding and a modular head for easy maintenance. The system also incorporates a breakpoint connection function and double-needle welding to avoid problems associated with single needle loosening or sticking.
