The Miyachi Unitek Series 300 electromagnetic weld head system is comprised of a linear magnetic force actuator manufacturer and a microprocessor-based electronic control, providing a precisely controlled weld force profile for miniature parts brazing. Weld-to-Displacement and programmable follow-up force features ensure welding consistency and virtually no splash when welding difficult materials such as copper, molybdenum, and tungsten. The Series 300 can interface with direct current, inverter, and stored energy manufacturers of power supply technologies.
