IMPORTANT! When using a pulsed welding current:
- The power source automatically regulates the pulse parameters in relation to the set
main current I
1
.
- No pulse parameters have to be set.
The pulsed welding current starts
- After the starting-current phase I
S
has finished
- With the UpSlope phase t
up
Depending on the set tAC time, the pulsed welding current can be stopped up to and in-
cluding the final current phase I
E
(tAC setup parameter to "On").
After the tAC time has passed, further welding is carried out at a constant welding current.
Set pulse parameters are available if applicable.
IMPORTANT! To set a defined tacking time, the setup parameter tAC can be combined
with the setup parameter SPt (spot welding time).
