5.13.4 Select welding current
The user has two options for setting the required welding current:
• Using the sheet metal thickness
• Directly as welding current
The welding current is displayed in the left-hand display. The “Material thickness” parameter can
be selected in the right-hand display.

5.13.5 Welding data display
The following welding parameters can be displayed before (nominal values), during (actual values) or
after welding (hold values):

After welding the hold values are displayed. When changes are made to the settings (e.g. welding
current) after welding, the display switches to the relevant nominal values.
The right-hand display automatically switches over to the material thickness after approx. 4 seconds.
If the “Program number” signal light is on in addition to the “Material thickness” signal light, the user is in
program mode- See 5.15 Welding programs chapter.
If the “JOB number” signal light is on in addition to the “Material thickness” light, the user is in a JOB in
the free memory.
