The Semi-Automatic Welding Machine

is a high-efficiency spot welding solution designed for consistent and repeatable lithium battery pack assembly. It combines manual flexibility with automated precision, making it ideal for medium to high-volume production where speed, accuracy, and weld quality are critical.

This machine features automatic welding triggering with controlled pressure and pulse energy, ensuring uniform weld strength while minimizing heat impact on lithium cells. It supports nickel and nickel-plated strips and is compatible with 18650, 21700, 26650, and 32700 cells.

With its robust construction, adjustable welding parameters, and built-in safety protections, the semi-automatic welding machine is widely used in EV battery manufacturing, ESS systems, solar battery packs, and professional battery workshops.
