PRO WELD
S etting the Weld Voltage/Capacitance
Slowly turn the voltage control knob
clockwise to increase the weld voltage until the
indi cator knob is pointing at the appropriate
number for the particular stud size that you are
welding. (See the set up information chart).
NOTE:
Once the voltage control knob is set to
a higher setting, turning it counter- clockwise
will NOT reduce the volta ge on the capacitor
bank, until the toggle switch (1) is turned
“OFF” (for approximately 10 seconds).
The settings are marked with the vol t-
ages corresponding to various stud sizes. The
approximate voltages for each stud size is as
follows:
45 – 60 VDC Min.
65 – 95 VDC 12 ga.
95 – 120 VDC #8
120 – 145 VDC #10
145 – 180 VDC 1/4”
180 – 185VDC MAX.
The voltage charge on the capacitor bank is read on
the digital panel meter. The ready light indicates
when the capacitors are c harged and a stud may be
welded.
Contact Light
The contact light indicates there is an a c-
cep t able electrical connection between the stud and
ground. This light will turn on when the stud is
placed in contact with the ground.
Trigger Light
The trigger light indicates there is a co m-
plete circuit to the unit through the gun control c a-
ble and switch. This light will turn on when the gun
trigger is pressed.
