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 "sequence parameter" push-button while simultaneously switching on the welding machine.
Release the "sequence parameter" push-button.
• The desired parameter can now be selected using the "sequence parameter" push-button. Parameter
rL1 must be adjusted 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 ad-
justment 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 new 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 Saving
• Press the "gas test" push-button.
5 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.
5.8 Power-saving mode (Standby)
You can activate the power-saving mode by either pressing the push-button
> see 4.3 chapter
for a pro-
longed time or by setting a parameter in the machine configuration menu (time-controlled power-saving
mode
)
> see 5.7 chapter
.
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. turning a rotary knob) deactivates power-saving mode and the ma-
chine is ready for welding again.
