Functions using the AVC firing mode specify weld current as
nn%I (representing the percentage of maximum available
current). Functions using the ACC firing mode specify a set
amount of secondary current, displayed as nnnn0 AMPS.

The weld data generated by the control (and displayed at the DEP or a
data monitoring device) does NOT include every function that provides
weld current. Keep this in mind when programming a weld schedule.
Only the following functions are included in the Weld Data display:

21 TEMPER nn CY/IMP mm %I
22 PREHEAT nn CY/IMP mm %I
23 POSTHEAT nn CY/IMP mm %I

25 WELD nn CY/IMP mm.m %I *
26 WELD nn HALF CYCLES mm.m %I *
* The stepper is active during this function. Functions #20–26
select the AVC firing mode.

For all weld functions, mm = 20 – 99. (The processor can fire a range
from 20% to 99% I.) For half-cycle functions, the range is from 20.0% to
99.9% I. AVC faults may occur when the control is firing at or near the
upper and lower limits (20 and 99%).
