SL-302A Mid Force Motorized Electromagnetic Weld Head – Offset Opposed Electrodes

Formerly known as 300 Series

The SL-302A electromagnetic weld head system includes both a linear magnetic force actuator and a microprocessor-based electronic control, for precisely controlled weld force for welding miniature and micro-miniature parts. Opposed offset electrode configuration. Programmable follow-up force and weld-to-displacement features ensure welding consistency and virtually no splash when welding difficult materials such as copper, molybdenum, and tungsten. Built in the USA, the SL-302A can interface with direct current, inverter and stored energy (capacitive discharge) power supply technologies.

  • Electronic Control of position, speed and force
  • Traceability of all Weld Head Functions
  • Weld-to-Displacement
  • Programmable Follow-up Force
  • I/O Ports for Automation Applications
