1 Preparation
• Switch off the welding machine.
• Remove the gas nozzle from the welding torch.
• Cut the wire flush on the contact tip.
• Slightly withdraw the wire at the wire feeder (approx. 50 mm). There should be no wire left in the
contact tip.
2 Configuration
• Push the „Welding parameter“ button and simultaneously switch on the welding machine. Release the
“Welding parameter” button.
• The corresponding parameter can now be selected using the „Welding parameter setting“ rotary knob.
It is essential to match the rL1 parameter for all machine combinations. A second matching with the
rL2 parameter has to be carried out if a second circuit is used on a welding system (e.g. two wire
feeders on one power source).
3 Matching / Measuring
• Carefully touch the torch with the contact tip on a cleaned area of the workpiece and push the torch
trigger for approx. 2 s. A short-circuit current temporarily flows which is used to determine and display
the new cable resistance. The value can be between 0 m
Ω and 40 mΩ. The newly established value is
instantly saved and does not have to be confirmed. If no value is shown on the right display the
measurement failed. Measuring has to be carried out again.
4 Restoring the machine
• Switch off the welding machine.
• Screw the gas nozzle onto the welding torch again.
• Switch on the welding machine.
• Re-inch the welding wire.
