IMPORTANT The following points apply to the pulsed welding current:
The power source automatically regulates the pulsing parameters as a function
of the pre-set main current I

.
The pulsed welding current begins:
-
after the end of the starting-current phase I
S
-
with the upslope phase UPS
Depending on what tAC time has been set, the pulsed welding current may con-
tinue up to and including the final current phase I
E
(tAC set-up parameter set to
"ON").
After the tAC time has elapsed, welding continues at a constant welding current,
and any pulsing parameters that may have been set continue to be available.
