Branson Series GMX-Micro Ultrasonic Metal Welders With Advanced Controls for Fast-Cycling, High-Precision Welds

The Branson Series GMX-Micro, a line of high-precision ultrasonic metal welders, feature a computerized operating system, multiple power levels and configurations, advanced controls, and improved connectivity. 

With 4,000 W of welding power, the GMX-Micro 4400W has a weld stack, while the more powerful 5,500 W GMX-Micro 5500W is available with either a metal welding stack or a direct press weld stack. The direct press stack exerts higher downforce with better stability, making it possible to complete complex, many-layered battery film welds or large-conductor welds with greater stability and consistency.

The welders feature a pneumatic actuation system that resets quickly (within 100 ms of weld completion), to enable faster weld cycles and 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-µ resolution that eliminates external measurement devices.

Users manage functions through a 7-in. LCD touchscreen or optional extended display that can develop, store, or retrieve weld recipes quickly. The display also graphs weld parameters—power, height, or frequency—in real time. The power supplies also provide weld-quality data and storage, multilingual operation, and easy software-based upgrades.

Designed to simplify configuration, automation, and mounting of single or multiwelder systems, both chassis offer expanded working space below the actuator, allowing for easier insertion and removal of large parts. Weld stacks also have quick-change tooling for rapid production changeovers.

Additional connectivity, including 1000/100/10 Mbps Ethernet, supports real-time data transmission to manufacturing execution systems (MES) or retrieval of stored production recipes via secure internet.

The welders easily handle material changes and production requirements for electric vehicle batteries, battery chargers, conductors, and electronics applications, with faster cycle times that can increase productivity and reduce costs.

Features:

  • Dual linear bearings for a smooth, precise welding process
  • Rigid polar mount support holds the stack completely, enhancing stability & repeatability
  • Compact actuator with spacious underneath for automation layout
  • Optional normal or direct press stack for different applications
  • Electronic & pneumatic circuit support higher PPM applications
  • Force output with air cylinder closer to or directly positioned on top of the welding area
  • Nodal support balances the Horn and Anvil during the welding process, effectively transferring ultrasonic energy for quality and consistency
  • Linear encoder for height and distance control
  • Control and power supply provide welding data
