Capacitive Discharge spot welders are one of the most cost-effective welding solutions for fine-spot resistance welding. CD welders have quick energy release, small heat affected weld zones, repeatable energy release independent of line voltage fluctuations, and are capable of extremely fine energy adjustment.
Two of the best sources we have found for purchasing welding equipment for strain gage use, are Vishay Micro Measurement and Sunstone Engineering. Below, you will find contact information to purchase directly from the manufacturer.
You may also order welding equipment through HPI along with your other strain gage purchases. Please contact our sales department for price and availability.
