Correction operation, threshold value setting (P7)
The correction operation is switched on and off for all JOBs and their programs at the same time. A
correction operation is specified for wire speed (DV) and welding voltage correction (Ukorr) for each JOB.
The correction value is saved separately for each program. The correction range can be maximum 30%
of the wire speed and +/-9.9 V welding voltage.
Figure 5-75
Example for the operating point in correction mode:
The wire speed in one program (1 to 15) is set on 10.0 m/min.
This corresponds to a welding voltage (U) of 21,9 V. When the key switch is set to "0" position, welding in
this program can only be carried out with these values.
To allow the welder also to perform wire and voltage correction in program mode, the correction mode
must be switched on and limit values for wire and voltage must be specified.
Setting of the correction limit value = WFlimit = 20% / Ulimit = 1.9 V
Now the wire speed can be corrected by 20% (8.0 up to 12.0 m/min) and the welding voltage by +/-1.9 V
(3.8 V).
In the example the wire speed is set on 11.0 m/min. This corresponds to a welding voltage of 22 V
Now the welding voltage can be corrected by further 1.9 V (20.1 V and 23.9 V).
The values for voltage and wire-speed correction will be reset if the key switch is moved to the "1"
setting.
