IMPORTANT! The following points apply to the pulsed welding current:
- The power source automatically regulates the pulsing parameters as a function of the
specified main current I
1
- There is no need to set any pulsing parameters
The pulsed welding current begins:
-
After the end of the starting current phase I
S
- With the upslope phase t
up
Depending on what tAC time has been set, the pulsed welding current may continue up to
and including the end current phase I
E
(tAC setup 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.
IMPORTANT! To set a specified tacking time, the tAC setup parameter can be combined
with the SPt setup parameter (spot welding time).
