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 or choke effect" push-button while simultaneously switching on the
welding machine. Release push-button.
•
"Welding parameter" push-button on the M3.7x-A and M3.7x-C control.
•
"Choke effect" push-button on the M3.7x-B and M3.7x-D control.
•
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 on 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.

5.11.3 Power-saving mode (Standby)

You can activate the power-saving mode by either pressing the push-button for a prolonged time or by
setting a parameter in the machine configuration menu (time-controlled power-saving mode).
When power-saving mode is activated, the machine displays show the horizontal digit in the
centre of the display only.
Pressing any operating element (e.g. tapping the torch trigger) deactivates power-saving mode and the
machine is ready for welding again.
