Capacitor Discharge Stud Welder
Capacitor Discharge Stud Welder(it is also called Capacitor Discharge Stud Welding Machine/Equipment, CD Stud Welder, CD Stud Welding Machine/Equipment) uses stored energy to generate the welding power, combining with the welding stud tip design to achieve good stud welding.
Capacitor Discharge Stud Welder is widely used in many fields like shipbuilding, electric switch equipment, communication devices, light industry machinery, household appliances, vehicle and rail vehicle manufacturing field, etc.
Now we have five types for different diameters of capacitor discharge welding stud: SSR-630, SSR-1250, SSR-1600, SSR-2500, SSR-3150.
