The Manual Spot Welding Machine (BTW Series) is built with industry-leading high-frequency welding technology, reaching up to 200kHz for rapid pulse output and exceptional welding control. The fast-rising welding current enables strong, stable welds while minimizing heat impact on the workpiece.
Featuring multiple control modes—including constant current, constant voltage, and combined control—the system provides precise energy regulation for complex welding tasks. With accurate timing control, air-cooled operation, and compact form factor, the BTW series is ideal for professional battery pack welding requiring reliability, precision, and efficiency.
Cell Aging Machines are designed to stabilize lithium-ion cells through controlled charge and discharge cycles, validating capacity, voltage consistency, and thermal behavior before assembly.

Battery Pack Testers perform complete electrical and safety validation, including voltage, current, insulation resistance, and protection checks.

LOCV Sorting machines measure open circuit voltage to group cells with consistent electrical characteristics, improving performance and lifespan.

Module Stacking systems precisely align and stack battery cells into mechanically stable modules for downstream processing.

Compression machines apply uniform pressure to enhance module strength, thermal contact, and long-term durability.

Laser Cleaning removes oxides and contaminants from battery tabs and terminals, ensuring clean, high-quality welding surfaces.

Vision-based polarity and CCD inspection detects alignment errors, defects, and missing components early in the process.

Laser Welding machines deliver precise, repeatable, high-strength joints with minimal heat impact.

End-of-Line testing validates electrical, functional, and safety performance before pack integration.

The Pack Line integrates final assembly, enclosure installation, and testing for scalable battery production.

EV battery production, energy storage manufacturing, battery research labs, electronics assembly, and OEM-based fabrication units.
This equipment is designed to support efficient and accurate battery assembly and testing workflows. With durable construction, precision control, and user-friendly operation, it delivers consistent performance for both small-scale and large-scale production environments.
