Capacitive Discharge Spot Welders

The Advantages of Capacitive Discharge Spot Welders

Capacitive discharge spot welders, also called capacitive resistance or Capacitor Discharge spot welders, have many advantages over other welder types:

  • Quick energy release for welding highly conductive metals such as copper
  • Small heat affected weld zones
  • Repeatable energy release independent of line voltage fluctuations
  • Capable of extremely fine energy adjustment

Capacitive Discharge spot welders are one of the most cost-effective welding solutions for fine-spot resistance welding. Whether you are manufacturing battery packs or microscopic assemblies, Sunstone Capacitive Discharge spot welders are the most affordable, precision fine-spot resistance welders on the market.
