Stud welding is a welding process where a “stud” (or similar metal part) is instantaneously end-joined to a metal workpiece. This process involves the same basic principles and metallurgical aspects as any other welding process. The equipment required to stud weld is composed of a direct current power supply, a controller, a weld gun and cables to tie the system components together.

The CD stud welding process produces weld power through a rapid discharge of the stored energy in capacitors. This stored energy is usually derived from a standard 115 volt AC source. CD stud welding, as a general rule, is used for studs 3/8" and less in diameter, (or where thin base metals or dissimilar metals are to be joined).

The SureShot II is a capacitor discharge stud welder. The weld energy is stored in a capacitor located inside the control unit. The amount of stored energy can be controlled by the UP or Down digital control pushbuttons located on the front panel as indicated by the digital display. CD weld studs, or pins, used with the SureShot II must have a specially designed projection at the weld end.

After installation, two setup phases must be completed before welding can begin. These phases are: • Weld Gun Setup, and • Controller Adjustment. Your weld gun setup will depend on your application and the particular pin or stud to be welded. Setting up the gun consists of the following: 1.
