5.1.2.1 Recurring welding tasks (JOB 1-100)
The user has 100 additional memory locations at their disposal to save recurring or different welding
tasks on a permanent basis. To do so, simply select the required memory location (JOB 1-100) and set
the welding task as described previously.
The three rotary knobs for AC frequency, AC balance and the tungsten electrode diameter are excepti-
ons. These settings are made in the operation sequence (signal lights with same name).
Switching a JOB is only possible if no welding current flows. Up-slope and down-slope times can be set
individually for latched and non-latched operation.

When one or more of the recurring welding tasks has been selected, the JOB signal light comes on.
5.1.3 Arc ignition
To change the ignition type, use parameter
to switch between HF start (
) and lift arc (
) in the
Expert menu
> see 5.1.11 chapter
.
5.1.3.1 HF ignition
Figure 5-3
The arc is started without contact using high-voltage ignition pulses:
a) Position the welding torch in the welding position above the workpiece (distance between the
electrode tip and the workpiece approx. 2-3 mm).
b) Press the torch trigger (high-voltage ignition pulses start the arc).
c) Depending on the selected operating mode, the welding current flows with the set start or main cur-
rent.
Ending the welding process: Release the torch trigger or press and release depending on the selected
operating mode.
