HF2 High Frequency Inverter Spot Welder

HF2 is a 2kHz, state-of-the-art high frequency inverter welding power supply used to join small parts at high speed. Built in the USA, the HF2 High Frequency Inverter Spot Welder, is a high speed digital adaptive feedback controls weld current, voltage, or power, providing better weld consistency as compared to traditional AC or CD technologies.

HF2 may be used in conjunction with one of our many weld heads as a single operator benchtop unit and is also well-suited for integration into semi or fully automated resistance welding systems.

  • High Frequency Inverter Welder DC Technology
  • High Speed Feedback Control System for Weld Current, Voltage, or Power
  • Graphical and Alpha-numeric User Interface
  • Input/Output Communication Ports for Automation Integration
