press it again to stop the output. If it is not pressed
again, the gas output stops after 30 sec..
3.4.1 Saving and calling up saved programs.
Button AP Saving
Press the key AP, the LED M lights along with AT if
the torch with U/D command is inserted. The display
O displays the abbreviation STO, and the display P indi-
cates the number (flashing if free, steady if occupied).
The first free program number is displayed; use the knob
Q to select the desired program number, then press the
key AP for more than 3 sec. When saving is complete,
the program number will stop flashing and remain
steady. Release the AP button to exit saving; the LED M
shuts off. Should you intend to overwrite a program,
when the button AP is held down for longer than 3 sec,
the number starts flashing, then returns to steady mode
to signal overwriting.
Saving must take place within the time in which the
display P shows the program number (5 sec).
Note: The program n° may be selected both by turning
the knob Q or, if the torch with the U/D button is inser-
ted, by pressing the left U/D key on the handle.
If you briefly press the AP button to display the memo-
ries and do not intend to use or change them, briefly
press the button AO to exit.
It is also possible to delete a saved welding program.
To do so, proceed as follows:
Press the key AP; the display O shows the abbreviation
Sto and display P gives the number. Use the knob Q to
select the saved welding program number. Turn the
knob N until the abbreviation "del" appears on the
display O. Hold down the AP Button for more than 3
sec.
If you wish to call up a saved program to change it, repeat
the steps described above, but use the knob N to select
the abbreviation "rCL" (recall - memory recall). Hold down
the AP button for more than 3 sec; the LED M shuts off,
and all of the settings of the program in question are set on
the panel.
Button AO Calling up saved programs
To call up a saved program, briefly press the button
AO. The display O shows the abbreviation PRG and
the display P indicates the number of the last program
used or, if they have never been used, the last program
saved. The LED M lights, use the knob Q or the left but-
ton of the U/D torch to select the program number. Five
seconds after choosing the displays O and P show the
values saved, and the machine is ready to weld.
When the LEDs M and AT (if the UD torch is inserted)
are lit, all adjustments are forbidden.
NOTE:You may display, but not edit, the values shown
by the LEDs J - K - L and B - C - D.
The remote controls will be inhibited.
To exit the saved programs press the button AO (twice if
the program number has disappeared), the LEDs M and
AT (if the torch UD is inserted) will shut off, and the
machine displays the last setting before the PRG button
was pressed.

NOTE: with the U/D button of the torch you may change
the program even while welding, and call up all of the
saved programs in sequence.
You may also call up in sequence welding programs of
the same type saved consecutively and bounded by two
free programs.
This function is carried out with the arc in use.
3.5 SERVICE FUNCTIONS MENU
3.5.1 Managing the cooling unit
Press the button AO and, holding it down, press the
button E to enter in a submenu.
Use the knob N to make your choice: H2O
Turn the knob Q to select the operating mode:
· OFF = off.
· On C = always lit
· On A = automatic start-up. When the machine starts,
the unit is running. If the torch trigger is not pressed, it
shuts off after 15 seconds. When the torch button is
pressed, the unit begins operating, and shuts off 3
minutes after the button itself is released.
Press the keys AO and E again to exit.
If the coolant pressure is too low, the power source deli-
vers no current and the message H2O will appear, fla-
shing, on the display O.
3.5.2 SP Spot-welding and stitch welding.
Active in two-stage (LED S) or four-stage welding (LED T).
Select using the knob N. The display P reads OFF. Turn the
knob Q until the message On appears on the display P to
activate the function.
Turning the knob N, select the item "tSP" (spot welding
time). The display P displays the time of 1 second. Use the
knob Q to set the time, between 0.3 and 5 seconds.
If you want to set stitch welding (welding with automatic
pause time), turn the knob N again so that the display P
reads "tIn" (stitch time). The display P reads OFF. Turn
the knob Q until a number appears, which will be the time
you select between welds.
3.5.3 Automatic Hot Start.(HSA).
Press the button AO and, while holding it down, press the
button E to enter a submenu.
Turn the knob N to select: HSA.
Turn the knob Q to select the type of operation:
OFF = Off
On = Active
Tthe function is active in synergic MIG programs when
two-stage welding (LED S) or four-stage (LED T) is
selected.
The operator may adjust:
1. The level of the "hot-start" current, LED AB.
2. Its duration, LED AD, range from 0.1-10 seconds.
3. The time to switch between the "hot-start" current and
welding current, LED AC.
The parameters set with LEDs AB, AC, AD can be
selected (knob N) and adjusted (knob Q) after selecting
function HSA, the abbreviations which can be selected
are the following:
SC = starting current corresponding to the LED AB.
Slo = Slope (interface time) corresponding to the LED AC.
tSC = Starting current time corresponding to the LED AD.
