MSK-310A Pneumatic AC Pulse Spot Welder for Battery Tab Welding, 110VAC USA Version
The MSK-310A is engineered specifically for the spot welding of battery tabs used in high-performance rechargeable batteries such as NiMH, NiCd, Li-Ion, LiMnNi, and LifePO4 chemistries. This model utilizes pneumatic actuation powered by compressed air to deliver consistent and controlled welding pressure, ensuring reliable and repeatable weld quality essential for battery manufacturing and research applications.
Operating on a 110 VAC power supply tailored for the USA market, the MSK-310A provides an average output power of 1500 W with pulse peaks reaching up to 10 kW. The welding current is continuously adjustable from 0 to 99%, allowing fine tuning to accommodate various tab thicknesses ranging from 0.03 mm up to 0.2 mm. The unit is not designed for welding ultra-thin foils below 20 microns; for such applications, ultrasonic welding is recommended.

Typical Applications
The MSK-310A is ideal for spot welding battery tabs during the assembly of cylindrical and prismatic cells in battery R&D and production environments. It supports welding of nickel, copper, and aluminum tabs commonly used in NiMH, NiCd, Li-Ion, LiMnNi, and LifePO4 battery chemistries. This welder is suited for research labs and manufacturers requiring precise, repeatable welds with pneumatic control.
Configuration and Operating Notes
The unit requires an external compressed air source operating between 0.1 and 0.8 MPa; the air compressor is not included but can be ordered separately. The included pedal switch enables hands-free operation for improved workflow. For applications involving ultra-thin foils under 20 microns, ultrasonic welding technology is recommended instead. Optional power supply modifications and certifications can be arranged to meet specific regulatory requirements.
