5.13.5 Welding data display
The following welding parameters can be displayed before (nominal values), during (actual values) or
after welding (hold values):
left-hand display
Parameter Before
welding
(nominal values)
During welding
(actual values)
After welding
(hold values)
Welding current
Parameter times
Parameter currents
right-hand display
Material thickness
Welding voltage
JOB number
Program number
When the settings are changed (e.g. welding current) after welding when the hold values are displayed,
the display will be switched to the relevant nominal values.
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 5.19 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 (JOB 128 to 256, - See 5.20.2 Creating a new JOB in the memory or copying a JOB
chapter).
5.13.5.1 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:

5.14 Arc
ignition
5.14.1 HF
ignition
Figure 5-16
The arc is started without contact from high-voltage ignition pulses.
a) Position the welding torch in welding position over the workpiece (distance between the electrode tip
and workpiece should be approx. 2-3 mm).
b) Robot start signal (high voltage ignition pulses ignite the arc).
c) Ignition current flows. The welding process is continued according to the operating mode selected.
End the welding process: Robot stop signal or other signals depending on the operating mode
selected.
