New Branson GMX-Micro ultrasonic welders offer advanced controls and better connectivity for faster welding of EV batteries, conductors and terminations

Emerson has launched the Branson™ Series GMX-Micro, a line of high-precision ultrasonic metal welders that feature a new computerised operating system, multiple power levels and configurations, advanced controls, and improved connectivity. The new welders are able to meet changing material and production requirements for electric vehicle batteries, battery chargers, conductors, and electronics applications, with faster cycle times that can increase productivity and reduce costs.

Redesigned and upgraded from the existing Branson GMX-20MA and GMX-20DP welders, the GMX-Micro series is available in two power levels: With 4,000 watts of welding power, the GMX-Micro is equipped with a standard weld stack, while the more powerful 5,500-watt GMX-Micro is available with either a standard metal welding stack or a direct press weld stack. The direct press stack is specially designed to exert higher downforce with greater stability, making it possible to complete complex, many-layered battery film welds or large-conductor welds with greater stability and consistency.

The GMX-Micro welders feature all-new power supplies and controls, including an upgraded pneumatic actuation system that resets more quickly (within 100 milliseconds of weld completion), to enable faster weld cycles and greater production rates. Weld stacks are held in rigid polar mounts, while actuators feature dual linear bearings, integral height calibration, and a linear encoder with 5-micron resolution that eliminates the need for external measurement devices. These features, together with a nodal support design that precisely balances the GMX-Micro weld stack and horn with the anvil during welding, ensure effective ultrasonic energy transfer and repeatable, high-precision bonding.
