Capacitive discharge resistance welding uses large capacitors to store energy for quick release. Figure 1 shows a typical capacitor discharge curve. Capacitive resistance welders have many advantages. Weld nugget formation takes place during the first few milli-seconds.
Capacitive welders deliver repeatable welds even during line voltage fluctuations. Spot welding relies on the principle of metal resistivity to heat and fuse metal. A large current is passed through the work piece. Energy is dissipated due to the metal resistance in the form of heat which melts and fuses weld materials. There are two phases to
Capacitive discharge welders allow extremely fast energy release with large peak currents. More of the energy goes into weld formation and less into heating surrounding material. The heat affected zone, where the properties of the metal have been changed from rapid heating and cooling, is localized to a small area around the weld spot.

The CD 700 is a capacitor discharge stud welder. The weld energy is storedin capacitors located inside the control unit. The amount of stored energycan be controlled by rotating the voltage control knob located on the frontpanel. CD weld studs, or pins, used with the CD 700 must have a speciallydesigned projection at the weld end.
When maximum energy has been reached the display will begin flashing. Sunstone Single Pulse welders have one knob for pulse energy control. Pulse energy is adjustable between 3% and 100% of the total stored energy. Each Sunstone welder is fully adjustable between its minimum and maximum energy.
