Capacitor discharge rod test cycle
Capacitor Discharge (CD) Stud Welding: Capacitors are charged to a predetermined setting on the power supply. When triggered, the stored energy is "discharged" and the burst of electricity creates the molten pool. The gun pushes the stud down into the molten pool. CD studs have a special tip on the end that is consumed during the weld.

Cyclic Charge Discharge (CCD) is the standard technique used to test the performance and cycle-life of EDLCs and batteries. A repetitive loop of charging and discharging is called a cycle. Most often, charge and discharge are conducted at constant current until a set voltage is reached. The charge (capacity) of each cycle is measured and the
Differences Between CD and Arc Systems
Capacitor Discharge stud welding is a semi-automatic arc welding process. However, with CD welding, you have the ability to weld small diameter studs to very thin material. Since the entire weld cycle is completed in several milliseconds, welds can be made to thin sheets of metal without pronounced distortion, burn through or discoloration.
