A capacitive discharge welder controls the voltage of the welding capacitors. However, the energy stored in the capacitor is a function of the voltage squared (E = ½*C*V2). This relation states that a small difference in voltage makes a large difference in weld energy. The energy adjustment knob on Sunstone spot
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.

Dead capacitor in mig welder, yes, no, maybe? What are signs?
If your capacitor goes open,it will make your open circuit voltage lower and make the arc less stable. If your capacitor goes short, it will make your welder act like it has stuck the wire tip to the work and maybe burn out the diodes. Usually a shorting failure will lead to the fluid in the capacitors erupting or leaking out.
