TIG Aluminium welding particularities (AC)
Balance principle
Balance : 20% Minimum cleaning
An alternative current is used to weld aluminium and its alloys. During the positive wave, oxidation is broken (cleaning).
During the negative wave, the electrode cools and the parts are welded (penetration). By modifying the ratio between
2 alternatives through the balance adjustment, you choose either cleaning or penetration.
Frequency principle
High frequency
Functions available according to welding mode
According to welding modes, some buttons do not work, please see table below :

* : In AC Easy mode, frequency and upslope are not accessible. Adjustments are automatic.
Memories saving and recall
There are 5 memories to save and recall TIG parameters. As well as these memories, the machine also stores the last
activated settings and recalls them when the machine is re-started.

Low frequency
The frequency enables adjustment of the arc concentration. The higher
the frequency, the more concentrated the arc. The lower the frequency,
the wider the arc. In AC mode, the frequency is manually adjusted. When
using AC Easy mode, this setting is automatically adjusted according
to the diameter of the electrode used and welding current. It is recom-
mended to use AC in Easy mode.

1- Press the button
2- «In» is displayed after 1 second.
As long as the display indicates «In», the action can be cancelled.
3- After one second, the display indicates a program number (P1 to P5), keeping
the button pressed, turn the wheel to select the memory number. Release the
button to store the parameters.
Recall a set-up
Proceed as above but after pressing the
Reset factory parameters
1- Press the reset button for 3 seconds.
2- The display indicates «Ini».
All stored memory has been deleted (the factory parameters have been restored
for the 5 programs + start parameters).
