In case of an error an error message is shown on the display mask.
This message can be hidden by means of the "Esc" key. If the error cause is
not remedied, the error message will be shown again after 10 sec.
The menu is quit by shortly pressing rotary knob 3!
9.3 Config - Compensation
Synergy characteristic curves are created under certain electrical and
physical conditions (cable lengths, cross sections etc.). Deviating conditions
are often prevailing during the daily welding applications. For this reason a
compensation must be performed. This is then stored as a welding circuit.
The voltage values depend on the size of the external circuit. When chang-
ing the external circuit, you have to determine the compensation again!
Before starting the measurement, make sure that either:
• there is no welding wire in the torch
or
• the welding wire is pulled off the torch so that the wire does not stick
out of the current tip.
Ensure that no welding wire touches the workpiece during the measure-
ment.
The measurement process is started on the operating module by means of
the rotary knob and is also possible from the torch trigger.
Proceed as follows in order to perform the measurement:
1. Remove the gas nozzle from the torch.
2. Select and confirm with the rotary knob in the "MAIN (2)" menu -->
"Config"--> "Compensation" --> "Enable measurement".
• The controller changes to the measurement mode.
3. Place the torch head firmly on the workpiece. The current tip must
touch the workpiece.
4. Press the torch trigger or select the menu item "Start measurement" at
the operating module to start the measurement.
• The measuring current is fed in.
• Measurement is finished after approx. 1 second. The measured
values are automatically displayed.
5. Repeat the measurement until the measured values only differ a little
bit. Normally four subsequent measurements are enough.
6. Store the last measured values in one of the 4 welding circuits (from
software version number x.02).
To select the active welding circuit, read the chapter "6.9 Main -
Programming - Welding circuit (from x.02)" on page 55.
