3.11 TIG (GTAW) Welding Secondary Parameters
Secondary parameters are available. These are required to be set separately.
• Press and hold the WELDING MODE (10) button then press the SAVE (54) button.
• Press the BACK button (22) or FORWARD button (23) to select the Parameter.
• Use the Multi Function Control (24) to adjust the parameter.
• Note that some parameters are only available in certain welding modes.
Note that even during welding, these settings can be adjusted and changed.

Ignition Peak Correction
The ignition peak current is
set after ignition to provide
stabilisation of the arc. A
different peak current is saved
for each selected tungsten
electrode diameter.

Plus terminal Correction
Ignition using the positive
welding terminal is used for
optimum dome formation in
AC GTAW welding. A different
plus terminal current is saved
for each selected tungsten
electrode diameter.

AC Arc Type
This enables working with low
