ABSTRACT OF THE DISCLOSURE Both process and apparatus are disclosed for testing arc stud welding guns. The process and apparatus are premised on generating two electric signals, the first of which occurs as a result of a switching action at the beginning of a welding operation. The second occurs when the welding stud impacts it's counter-electrode. The elapsed time between these signals is measured and used as a basis to determine the effectiveness of the arc stud welding gun. Process and apparatus are both disclosed for testing during actual and simulated arc welding.
