The Branson Series GMX-Micro, a line of high-precision ultrasonic metal welders, features a new computerized operating system, multiple power levels and configurations, advanced controls and improved connectivity. They are built on a compact, modular chassis, with two styles based on the choice of normal or direct-press actuator, and both chassis offer expanded working space below the actuator. The GMX-Micro series is available in two power levels: With 4,000 watts of welding power, the GMX- Micro 4400W is equipped with a standard weld stack; the more powerful 5,500-watt GMX- Micro 5500W is available with either a standard metal welding stack or a direct press weld stack. The welders feature all-new power supplies and controls, and users of the GMX-Micro power supplies can manage welder functions through a standard 7-in. LCD.
