SELECTING THE SPRING LOAD
The proper spring pre‐load setting on the stud gun will vary depending on the se‐
lected application. Generals rules of application would be; mild steel or stainless
steel usually in the 1 to 2 range, depending on the stud diameter and the thickness of
the base material. Aluminum and other nonferrous metals would require settings
from 3 to 5 depending on the diameter of the stud and base material thickness.
This spring pre‐load adjustment is made by turning the back cap of the stud gun. On
the side of the stud gun is the indicator numbered 1 thru 5, which will show you the
tension setting during the adjustment.
