MAKING A TEST WELD
After verifying that the welding system is installed and your weld gun is
setup properly for your application, the final step is to adjust your stud
welding controller to the proper settings.
1. (Before turning on power) turn the controller
VOLTAGE
selector
switch to “ MIN ” (fully counterclockwise.)
2. Turn the controller
ON/ OFF
switch to “
ON
.” Verify by observing
“ POWER ” lamp.
3. Using the chart below, adjust the
“VOLTAGE”
control until the
“WELD VOLTAGE” meter reads the desired value.
The chart settings shown below are "reference" settings to be used as
starting points. Actual voltage settings may vary depending upon the
conditions or each application and use. The voltages shown also assume
that the following are in use (as described in previous Installation and
Setup sections of this manual.)
A) Straight polarity cable set ups in use (Gun = Negative, Ground = Positive.)
B) Ground connection directly to the part to be welded and connected in
a clean, solid manner.
C) 1/8" protrusion of pin/stud onto work (3/16" for Aluminum) causing
an equal amount of spring pressure in the gun.
D) “Silver” gun spring for Mild or Stainless Steel, “Black” for
Aluminum applications.
E) Good, clean accessories and work surface to be welded, with proper setup of
all accessories.
