High Precision Weld Head System with Force and Displacement Control The Series 300 electromagnetic weld head system (U.S. Patent #5386092, #5225647) is comprised of a linear magnetic force actuator and a microprocessor-based electronic control, providing a precisely controlled weld force profile for miniature parts welding. By showing actual displacement (set-down) with .0001 inch (2.5 µm) resolution, the graphical screen allows the user to fine tune the weld time, follow-up force, and weld energy relationships between the Series 300 and the external welding power supply. The built-in displacement monitoring feature can be used to optimize the weld and isolate potential quality problems. KEY FEATURES • High speed resistance spot welding weld head TYPICAL APPLICATIONS • Programmable force and weld positions • Excellent force and position repeatability • Displacement monitoring • I/O ports for automation Squib weld Fine wires Hearing aids Medical devices RESISTANCE WELDING
