It is possible to select the desired welding functions.
With each function key pressed you are selecting
a welding function.
IMPORTANT: VERTICAL FUNCTION KEYS DO NOT
WORK DURING THE WELDING STAGE.
Covered Electrode Welding MMA
By pressing the function key 4 and taking the luminous
indicator on symbol 1 - Picture 1 Page 6.) you can select
the mode of electrode welding.
Welding TIG DC HF
By pressing the function key 4 - Picture 1 Page 6.) you
can select the mode of TIG welding with high-voltage
start until the luminous indicator reaches the position on
symbol 2 - Picture 1 Page 6.), If you press the torch
button you will get a high-voltage discharge that allows
the arc fusing.
TIG DC Welding with Lift Start
By pressing the function key 4 - Picture 1 Page 6.) you
can select the mode of TIG welding with lift start until the
luminous indicator reaches the position on symbol 3 -
Picture 1 Page 6.).
In this mode the arc fusing occurs with the following
sequence:

If the electrode points to the welding piece it
provokes the short-circuit between the piece and the
electrode.

Pressing the torch key the pre gas is set. The end of
the pre gas is indicated by a long BEEP. If that
operation is carried out starting from the post gas
you get the long BEEP immediately as soon as you
press the torch key.

During the BEEP it is possible to lift the electrode
from the piece provoking the arc fuse.
Two Times Welding
Active only in TIG mode.
By pressing the function key 8 - Picture 1 Page 6.) you
can position the luminous indicator on symbol 5 - Picture
1 Page 6.). In this mode you press the torch button to
prime the welding current and it should be pressed whilst
welding.
Four Times Welding
Active only in TIG mode.
By pressing the function key 8 - Picture 1 Page 6.) you
can position the luminous indicator on symbol 6 - Picture
1 Page 6.). In this mode the torch button works in four
times for an automatic weld. The gas flux is activated by
first pressing the torch button. By releasing the button
the welding arc is primed. The second pressing on the
torch button interrupts the welding. By releasing the gas
flux is deactivated.
Spot Welding
Active only in TIG mode
can position the luminous indicator on symbol 7 - Picture
1 Page 6.). In this mode you obtain a spot welding timed
with a set up timer as described on reference 24 - Spot
time.
