Typical Applications
The MSK-521 is suited for battery research and production environments focused on cylindrical lithium-ion cells. It enables precise preparation of electrode strips with integrated tab welding and taping, essential for consistent cell assembly and performance testing.
Configuration & Operating Notes
The system requires an external compressed air supply within the specified pressure range for operation; an air compressor is not included. If using a gas cylinder instead, a two-stage pressure regulator must be installed to ensure safe pressure levels. The PLC touch screen facilitates easy adjustment of cutting length and welding parameters. Regular maintenance of blades and welding heads is recommended to maintain performance.
