5.9.6 Welding data display
The following welding parameters can be displayed before (nominal values), during (actual values) or
after welding (hold values):
“Left-hand display”

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 (programs 1-15, see chap. “Welding programs”).
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 (JOBs 128 to 256, see chap. “Creating a new JOB in the free memory”).
5.9.6.1 Welding parameter setting
During the welding parameter setting process, the parameter value being set is displayed on the left-hand
display. The right-hand display shows the “Factory setting” or a variation of it upwards or downwards.
Displays, e.g. when setting the ignition current, and their meanings:
