Capacitor Discharge (CD) Stud Welder - CD-3101

Capacitor Discharge (CD) Stud Welder - CD-3101


The CD-3101 is a cost-effective standard capacitor discharge stud welding unit. It is suitable for tip ignition with contact and gap.

The CD-3101 is compact with a strong metal housing. It will weld mild steel, stainless, aluminum and brass CD studs.

  • Operation at high voltage fluctuations (-25% up to 20%)
  • Integrated mains filter
  • High-tech micro controller to guarantee precise process control
  • Safest operating conditions and highest operating comfort
  • Stepless voltage regulation (charging and discharge)
  • Automatic discharge of capacitors by reducing the loading voltage
  • Easy and reproducible setting of the loading voltage / welding energy by digital display
  • Library function - automatic adjustment of the loading voltage by selecting the stud diameter (fine adjustment by pushing arrow key)
  • Error code indication by digital display
  • Easy control of all functions by LED indications
  • Easy change of polarity of welding voltage by interchanging welding current cable and ground cable (if required)
  • Electronically protected magnetic circuit when using gap gun CA-08
  • Temperature controlled cooling fan reduces contamination inside the power unit (high reliability) and reduces noise
