STUD WELDER 2008 ABOUT STUD WELDER CAPACITOR DISCHARGE Stud welding is an electric process in which high electric energy is send at joint for just for one to three milli-second, that results in an arc blast that melts stud & base metal surface and a spring force instantly pushes stud towards iron sheet surface and the weld joint forms. In CD stud welder a capacitor bank is charged from 30 to 180 Volt according to weld stud size. When triggered, the energy stored in capacitors is discharged on weld area and the burst of electricity demolish gap pin on stud head and creates the molten pool. The gun pushes the stud down into the molten pool. (CD studs have a special pin on the head to maintain gap between stud & base-metal. The pin merges in weld pool during the weld.) Studs can be weld with common welding process like: Manual arc, Mig welding or Tig welding. But CD stud welding is best preferred pr
