• The CD3101 is a cost-effective standard capacitor discharge stud welding unit. It is suitable for
tip ignition with contact and gap. The CD3101 is compact with a strong metal housing. It will weld mild
steel, stainless, aluminum and brass CD studs.
• The CD3101’s many features include: 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; temperature control of
transformer and interior of power unit – automatic shut off at overheat; highest safety standard by automatic
control of SCR and contact to work piece; recorded high voltage test; EMC-tested.
