O - Display
Displays:
1.in no-load conditions, the preset current.
2.under load, the welding current and its
levels.
3. in combination with the "Hold" LED lit, the last
welding current.
4. In pulsed TIG mode, loaded, the alternating currents in
the corresponding levels.
5. within the synergic parameters, the current in relation
to the selected thickness.
6. the message "H2O" when the cooling unit is set, and
the same message flashing when the cooling unit
pressure switch is tripped.
7. the message "OPn" flashing when the thermostat is
tripped.
8. while selecting free or saved programs, the message
PL ...P01...P09
9. abbreviation MMA.
Led N
Cannot be selected and lights when the display O dis-
plays a current.
U - Display
Displays:
1.
the no-load voltage,
and when welding the loaded voltage.
2. in continuous TIG mode, with button not pressed,
zero; with button pressed but without welding, the
no-load voltage, and when welding the loaded
voltage.
3. displays numerically all values except for currents
selected using the button AP.
4. displays the numerical combinations that refer to the
various wave forms that may be selected when the AP
button is used to select the LED AY (Wave).
5. when setting up the cooling unit, the messages: OFF,
OnA, OnC.
6. in MMA type of current abbreviations: AC, DC.
7. in synergic mode (LED I lit) the abbreviation of the
materials to be welded if the LED L is selected; the
abbreviations of the welding positions if the LED M is
selected; and the electrode diameters if the LED R is
selected.
ADDITIONALLY, with the LED P (Hold) lit, it displays
the welding voltage.
LED Q
May not be selected and lights when the display U dis-
plays a voltage.
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. A
working program PL is also available.
Selecting
When this push-button is pressed briefly, the display O
shows the next program number after the one being
used. If it has not been saved the message will flash, oth-
erwise it will remain steady.

in MMA mode without welding,
Saving (3.6)
Once the program has been selected, hold for more than
3 seconds to save the data. In confirmation, the program
number on the display O will stop flashing.
AP - SELECTOR SWITCH
When this button is pressed, the LEDs light in suc-
cession:
Warning: only those LEDs that refer to the chosen weld-
ing mode will light; i.e., in continuous TIG welding mode
the LED AE, representing the pulse frequency, will not
light.
Each LED indicates the parameter that may be adjusted
by means of the knob Y while the LED itself is lit. Five
seconds after the last change, the LED involved will shut
off; the main welding current will be displayed, and the
corresponding LED AG lights.
SELECTORS AQ + AP = SECOND FUNC-
TIONS
Access to «second functions» menu is obtained by press-
ing simultaneously knobs AQ and AP for more than 3
seconds.
Selection of «MENU» entries is obtained by means of a
short pressure on knob AP.
Exit from this «MENU» is obtained by means of a short
pressure
on knob AQ.
Display O shows the function, display U shows the set-
ting that can be controlled by means of knob Y.
