99.9% I. AVC faults may occur when the control is firing at or near the
upper and lower limits (20 and 99%).
NOTE:
When Function #60 appears before any weld function in a schedule, the
control displays IMP (impulses) rather than CY (cycles) to indicate the
weld control will pulsation weld. Refer to Function #60 on page 4-7 for
more information.
Automatic Current Compensation Firing Mode
The following weld functions will select the Automatic Current
Compensation (ACC) firing mode.
30 WELD nn CY nnnn0 AMPS*
31 TEMPER nn CY nnnn0 AMPS
32 PREHEAT nn CY nnnn0 AMPS
33 POSTHEAT nn CY nnnn0 AMPS
34 PRE-WELD nn CY nnnn0 AMPS
38 WELD nnn IMP nnnn0 AMPS nnnn0 AMPS
* The stepper is active during this function.
NOTES:
ACC faults may occur when the control is firing at or near the high and
low range of current. The current range for each control is unique and
depends on factors such as the size of the weld transformer. Experiment
with the control to determine the upper and lower range of current each
control can provide.
When Function #60 appears before any weld function in a schedule, the
control displays IMP (impulses) rather than CY (cycles) to indicate that
the weld control will pulsation weld. See Function #60 on page 4-7 for
more information.
