Key Features • Electronic control and traceability of all weld head functions Ensures repeatable weld head schedules that can be electronically dictated and documented for GMP, TQC, and ISO 9001. • Weld to displacement Ensures consistent weld nugget size by controlling the amount of material collapse or set-down; excellent diagnostic tool for monitoring welding process. • Programmable follow-up force Ensures consistent weld quality by preventing molten metal from escaping from the weld joint. Superior to pneumatic or spring weld force systems. • I/O ports for automation applications Remote displacement or weld force profile schedule selection for simple automated applications via RS232/RS485 communications. • High speed weld head • Programmable force and weld positions • Excellent force and position repeatability • Displacement monitoring • I/O ports for automation 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 (2.5ìm) 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. resistance welding Series 300 High Precision Weld Head System with Force and Displacement Control Program Mode – Weld Force Profile Run Mode – Actual Weld Displacement
