1 Preparation
•
Switch off the welding machine.
•
Unscrew the gas nozzle from the welding torch.
•
Trim the welding wire, so that it is flush with the contact tip.
•
Retract the welding wire a little (approx. 50 mm) on the wire feeder. There should now be no more
welding wire in the contact tip.
2 Configuration
•
Press the "Welding parameter" push-button while simultaneously switching on the welding machine.
Release the "Welding parameter" push-button ("Choke effect" push-button with drive 4X LP).
•
The required parameter can now be selected using the 'Welding parameter setting' rotary knob.
Parameter rL1 must be aligned for all machine combinations.
In case of welding systems with a second power circuit – if two wire feeders are to be operated from a
single power source, for example – a second alignment with parameter rL2 must be performed.
3 Alignment /measurement
•
Applying slight pressure, put the welding torch in place with the contact tip on a clean, purged location
on the workpiece and then press the torch trigger for approx. 2 seconds. A short-circuit current will
flow briefly, which is used to determine and display the cable resistance. The value can be between
0 mΩ and 40 mΩ . The new value is immediately saved without requiring further confirmation. If no value
is shown in the right-hand display, then measurement failed. The measurement must be repeated.
4 Restoring welding standby mode
•
Switch off the welding machine.
•
Screw the gas nozzle onto the welding torch.
•
Switch on the welding machine
•
Insert the welding wire.
