HF-2500A High Frequency Inverter Spot Welder

Formerly known as HF25

The HF-2500A high frequency inverter spot welder addresses the challenges of micro welding for a wide range of applications. Precise control of weld energy with high speed closed loop feedback and weld quality tools ensure high yields for the most demanding welding applications. Built in the USA, the HF-2500A high frequency inverter spot welder may be used in conjunction with one of our many weld heads as a single operator benchtop resistance welder and is also well-suited for integration into semi or fully automated resistance welding systems.
