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:

HF ignition
Figure 5-6
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.
