INSPECTING THE WELD
Visually inspect the weld. A good weld will result in an all‐around weld, with a small
visible amount of weld surrounding the flange of the stud. Too much splatter and the
weld is too hot, lower the voltage. No splatter and the weld is too cold, increase the
voltage.
If you get weld flash to one side of the stud as opposed to an even amount around
the base of the flange, this is called “arc blow”, and can be solved by repositioning
the ground clamp or using a dual ground clamp.
Proper welded studs can be tested by either torquing or bending the stud. The
welded flange of the stud should stay in place using either method, even though the
threaded portion of the stud breaks. If the base material is very thin, then a full slug,
the diameter of the flange will pull from the base metal for a properly welded stud.

SET-UP AND WELDING
TESTING YOUR SETTINGS
When you have performed all of the presets as discussed in this manual, it is recom‐
mended that you perform several test welds with the same diameter stud and base
material that you will be using. This will verify that all of the settings are correct to
the results you desire. Welding is done by placing the stud into the collet, and press‐
ing the stud gun to the work piece, compressing the spring. This is why the stud must
protrude beyond the foot piece at least 1/8”.
Holding the gun perpendicular to the work piece, and aligning the stud to the desired
position on the work piece, press down so that the foot piece is flush with the work
piece (spring compressed), and depress the trigger.
When removing the stud gun from the welded stud, always lift the stud gun vertically
from the welded stud in order to maintain the proper tension of the collet. Spreading
the collet when lifting the stud gun from the welded stud will shorten the life of the
collet and will eventually create an undesirable weld.
