If the lower power time correction is reduced, the process frequency increases
and the LSC process phase becomes shorter.
Lpc (1)
Lower power correction
To set the energy input in the cold process phase in a mixed process
Setting range: -10.0 - +10.0
Factory setting: 0
If the lower power correction is increased, this results in a higher wire speed and
therefore higher energy yield in the cold LSC process phase.
R/L alignment Align the welding circuit resistance (R) and welding circuit inductivity (L) if one of
the following components of the welding system is changed:
-
Torch hosepacks
-
Return lead cables, welding power-leads
-
Welding torches, electrode holders
-
Push-pull units
Prerequisites for R/L alignment:
The welding system must be complete: closed welding loop with torch and torch
hosepack, wirefeeders, return lead cable, interconnecting hosepacks.
Performing R/L alignment:
1
Select Setup menu / Process param. / R/L-check / alignment
2
Press the right adjusting dial
The current welding circuit inductivity values in µH and welding circuit resistance
values in mOhm are displayed.
3
Press the right adjusting dial (or press the torch trigger)
"Connect earth" is shown on the display.
4
Establish a safe ground earth connection
IMPORTANT! Contact between the earthing clamp and workpiece must be
established on a cleaned area of the workpiece.
5
Press the right adjusting dial (or press the torch trigger)
"Remove nozzle" is shown on the display.
6
Remove the gas nozzle from the welding torch
7
Press the right adjusting dial (or press the torch trigger)
"Contact workp." is shown on the display.
8
Place the contact tip of the welding torch flush against the workpiece sur-
face
9
Press the torch trigger
(or press the right adjusting dial)
After a successful measurement, the current values are displayed.
