9.2 Weld Test and Inspection
Testing of weld quality beyond visual inspection varies
with stud characteristics.
Refer to AWS (American Welding Society) Structure
Welding code AWS D.1Rev. 1-76.
Welding procedures are covered in Sections 4.28 and 4.29.
Weld test and inspection is covered in Section 4.30, para-
graphs 1 through 4. (American Welding Society, inc., 2501
N.W. 7th. Street, Miami, Fla. 33125)
9.0 SETTING UP THE POWER SOURCE
9.1 Connections and settings.
CAUTION
Turn the power off before making connections
a)
Connect the male end of the GROUND CABLE to the posi-
tive GROUND terminal of the power supply, and secure the
“C” clamp to the base plate. Make sure both connections are
tight and the base metal is free of heavy paint or rust at the
ground connection points.
b)
Connect the male end of the COMBINATION CABLE SET
to the negative GUN terminal of the power supply.
c)
Plug in the control cable portion of the COMBINATION
CABLE SET into the control cable receptacle in the front of
the power supply.
d)
Set the Time adjustment required for the particular stud size.
(see table 9-1)
e)
Set the Current adjustment to the current setting for the par-
ticular stud size. (see table 9-1)
f)
Turn on the power supply by depressing the START button.

WELD INSPECTION
A. Bend Test
Repeatedly bend the stud away from its axis until failure oc-
curs.
B. Torque Test - Threaded Studs
Twist the stud to point of failure. Apply a twisting tensile load
by using a collar, washer and nut.
C. Test Results
In an acceptable weld, failure will occur in the stud material
or tear out of a thin base plate. Failure in the weld requires
adjustment of procedure, weld time, weld current, or gun
