led T lights while led V shuts off. To stop welding at any
time, simply hold down the torch trigger for more than
0.7 seconds, then release it; the current starts to decre-
ase down to zero in the "slope down" time previously set
(led W on).
During "slope down" phase, if you press and immediate-
ly release the torch trigger, the current goes back to the
previously set lower level.
IMPORTANT: "PRESS AND IMMEDIATELY RELEASE"
refers to a maximum 0.5 sec. time.
M - LED. TIG 2 stages pulsed welding (ma-
nual).
When the torch trigger is pressed, the current begins to
increase over the previously set "slope up" time, until it
reaches the value set by means of the knob AA. When
the trigger is released the current starts to decrease over
the previously set "slope down" time and returns to zero.
In this position the pedal control accessory ART. 193 can
be connected.
N - LED. TIG-pulsed 4 stages welding (au-
tomatic).
This program differs from the previous one in that the arc
is both started and shut off by pressing and releasing the
torch trigger.
PP - LED. TIG- pulsed 4 stages double le-
vel welding (automatic).
The welding process mode is the same as the one de-
scribed for led I. Once the fi rst level peak currents are
set, the ratio between them will be kept in the second
level as well.
AA - KNOB
Set the welding current at 10-180A in MMA
and 5-220A in TIG.
Together with button P it is possible:
-to set the current second level V
-to set the "slope up" S
-to set the "slope down" W
-to set the pulse frequency AE
-to set post gas X
-to set AC welding current frequency Q
-to set wave balance in AC welding R
U - Display
Shows:

and during welding the load voltage.
2. In TIG continuous, without pressing the torch trigger,
the abbreviation PL (free program).
In TIG continuous, when pressing the welding torch
trigger, but without welding, the open-circuit voltage.
In TIG continuous when pressing the torch trigger,
but while welding, the load voltage.
3. Displays by the number all sizes, except current
ones, selected by means of button P.
4. Displays all the abbreviations of the service fun-
ctions menu.
5. Abbreviation "OPn" fl ashing when the thermostat is on.
6. During the selection of free or saved programs abbre-
viations PL...P01...P09.
In MMA the open-circuit voltage
O - Display
Shows:

current
2. In load conditions, the welding current and its levels.
3. In TIG-pulsed, load mode, the currents changing
from one level to the other.
4. Shows all sizes and the value of the second fun-
ctions menu.
AQ - SELECTOR SWITCH
Selects and saves programs.
The welding machine can save nine welding pro-
grams P01.....P09, and call them up using this button.
The work program PL is also available.
Selection
If this button is briefl y pressed the display U shows the
number of the program following the one being used. If it
has not been saved the message will fl ash, otherwise it
will remain steady.
Saving (see par.3.6)
Once the program has been selected, if the button is
pressed for more than 3 seconds, data are saved.
As confi rmation, the program number on the display U
will stop fl ashing.
P – SELECTOR SWITCH
When this button is pressed, the LEDs light in suc-
cession:
Important! only those LEDs that refer to the chosen wel-
ding mode will light; i.e. in TIG-continuous led Q that re-
presents the pulse frequency will not glow.
Each led shows the parameter that can be set by means
of knob AA during the time when the led is glowing. 5
seconds after the last change the concerned led shuts
off and the main welding current is shown and the corre-
sponding led T glows.
LEDS THAT MAY BE SELECTED ONLY IN TIG DC (DI-
RECT CURRENT OR TIG AC WELDING (ALTERNA-
TING CURRECT)) :
AL- Pre-gas Led
Setting 0.05 to 2.5 seconds. Gas deli-
very time before welding starts.
S - Led Slope up.
This is the time in which the current,
beginning from the minimum, reaches
the set current value. (0-10 sec.).
T - Main welding current Led.
V - Basic or second level welding
current Led.
This current is always a percentage of
the main current.
AE - Pulsed frequency led (0.16-500
Hz).
