MSK-DSAW-AR18650 Automatic Double-Side Welding Machine for Cylindrical Battery Packs
The MSK-DSAW-AR18650 is engineered to address the demanding requirements of welding cylindrical battery cells such as 18650, 26650, 32650, and 32700. It facilitates simultaneous welding on both the top and bottom sides of battery packs, ensuring efficient and consistent electrical connections. This machine is particularly suited for battery pack assembly lines where precision and speed are critical.
Welding operations are controlled via a PLC system with an intuitive LCD touch screen interface, allowing up to 35 programmable welding profiles. The machine incorporates real-time welding current monitoring and an automatic alarm system to prevent poor quality welds. Additionally, it supports arbitrary point restarting after welding adjustments and programmable skipping of specific battery cells during the welding process.
Key Features
- Simultaneous double-side welding with two independent 15 KVA power supplies delivering up to 5000 A current each.
- Real-time welding current monitoring and automatic alarm system to ensure weld quality.
- Programmable welding time adjustable from 0 to 299 ms and welding current adjustable between 800 A and 5000 A.
- Automatic XY stage with triaxial servo motors providing a working range of 450 mm (X-axis) by 250 mm (Y-axis).
- Welding needles made of alumina copper with 1.7 mm diameter and 85 mm length, cooled by fans for durability.
- Supports nickel tab thickness from 0.1 mm to 0.2 mm with maximum tension force of 6 kg during welding.
- PLC control with USB communication port for easy program upload/download and storage of detailed welding parameters.

Configuration & Operating Notes
The MSK-DSAW-AR18650 includes two sets of insulative wood cylindrical cell holders for 18650 cells as standard. Custom cell holders for other sizes are available at additional cost. The machine requires an air compressor supplying 0.4 to 0.8 MPa air pressure; if a gas cylinder is used instead, a two-stage pressure regulator must be installed to ensure safe operation within the specified pressure range. The system features emergency stop and alarm functions for operator safety and quality assurance.
