Series 300 Weld head System


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 (2.5μm) 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

- 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.

Graphical Weld Display Graphical display of programmed weld force profile and actual displacement.
Weld Force Profiles The user can write/save 128 different weld force profiles. Schedules 1 through 127 can be protected. Schedule 0 is used as a scratchpad for schedule development.
Object Detection Detects the presence of objects located directly in the electrode path between the up-stop position and the search position and will automatically bring the electrode back to the up-stop position.
Run/Dress Mode Provides adjustable electrode force to easily clean electrodes and then automatically re-calibrates the absolute position of the closed electrode tips.
