The measurement is finished when the welding circuit resistance is shown on the
display in mOhm (for example 11.4).
Fit the gas nozzle back onto the welding torch
Ensure that the workpiece has an optimum contact surface in the area of the
earthing clamp (clean surface, no rust, etc.).
Ensure that the Stabelektroden-Schweißen welding process is selected
Establish a ground earth connection to the workpiece
Access the Setup menu 2nd level (2nd)
Select parameter "r"
Ensure that the workpiece has an optimum contact surface for the electrode
(clean surface, no rust, etc.).
Place the electrode flush against the workpiece surface
Press the "Parameter selection" button (right)
The welding circuit resistance is calculated. During the measurement the dis-
play shows "run".
