5.10.7 TIG welding data display
Diagram 5-31
The button for the welding parameter display mode is next to the display.
Each time the button is pressed it switches between welding current and welding voltage.
The display shows:
•
Nominal values (before welding)
•
Actual values (during welding)
•
Hold values (after welding)
Parameter

The display switches back from hold values to actual values for approximately 5 s after welding is
finished.
5.10.7.1 Power-saving mode
The power-saving function can be activated either by pressing the button for a longer time (see chapter
"Machine description – Short overview") or by setting a parameter in the configuration menu (time-based
power-saving mode).
When power-saving mode is activated, both machine displays show the horizontal digit in the
centre of the display only.
Pressing any operating element (e.g. tapping the torch trigger) deactivates power-saving mode and the
machine is ready for welding again.
5.10.8 TIG arc ignition
5.10.8.1 Liftarc ignition
Figure 5-32
The arc is ignited on contact with the workpiece:
a) Carefully place the torch gas nozzle and tungsten electrode tip onto the workpiece and press the torch
trigger (liftarc current flowing, regardless of the main current set).
b) Incline the torch over the torch gas nozzle to produce a gap of approx. 2-3 mm between the electrode
tip and the workpiece. The arc ignites and the welding current is increased, depending on the
operating mode set, to the ignition or main current set.
c) Lift off the torch and swivel to the normal position.
Ending the welding process: Release or press the torch trigger depending on the operating mode
selected.
