Voltage
Compensa-
tion Limit
(See p. 6-4)
The control could not
fully compensate for
a drop or surge in
supply line voltage. Check the nominal contactor
voltage setup parameter. Try recalculating the nominal
contactor voltage setting.
Too much load on the line
when attempting the weld. Check line voltage.
Adjust tap settings on the
weld transformer, and/or
adjust weld heat away from
extreme values. Heat may be set at too high or
low % current for the control to
compensate for line voltage
variations. Avoid programming
values of 20%I or secondary
current that is too low.
Steppers are pushing the
total % current (programmed
c boost) over the
threshold. Adjust the stepper boost.
Insufficient
Line Voltage
(See p. 6-5)
The weld initiate was
removed, or time
expired while the
control was waiting
for the programmed
line voltage in
Function #72 or #73. Overloading of the weld bus. Re-distribute weld bus load.
Brown-outs of the power
source. Measure bus voltage with no
load. Ensure that it is providing
the necessary voltage. (Confirm
this by observing the low line
voltage on the Weld Data
display of the DEP.)
