Stud Welding

The arc stud is loaded into the stud gun chuck
A ferrule is placed into the ferrule grip
The operator initaites the weld cycle by pulling the gun trigger
The gun lifts the stud up form the work, drawing a pilot arc
The pilot arc establishes a path for the weld current which comes on after the stud is lifted
The stud remains lifted for the duration set on the controller. During this time the weld current is melting both the stud and the parent metal
When the time set on the controller has elapsed, the gun plunges the stud into the molten pool of parent material and the weld is completed
The ferrule is broken away and discarded
