Impedance (L)
· Within the saved programs select the desired program
number.
All of these values are shown on the display (P) and are
selected by the button I.
In the service functions select the abbreviations: OFF,
OnC, OnA, SAu, rES, On.
Button I
Each pressure selects the value adjustable via the
Knob Q.
The values that may be selected are in relation to the
type of welding process selected.
LED J Voltage
In all MIG welding processes, indicates that the
display P shows the preset voltage or, in combina-
tion with the lighting of LED F, the actual welding
voltage.
in TIG and MMA modes it always remains lit, and may
not be selected. IIndicates that the Display P displays
the open-circuit voltage or welding voltage or, in combi-
nation with LED F lit, the actual welding voltage.
LED K Arc length
Adjustment -9,9 ÷ +9,9.
In all synergic MIG programs the display P shows a
number. Zero is the manufacturer setting; if the
number is set to negative, the arc length diminishes,
if set to positive it extends.
The arc length is also displayed by turning the knob Q
while displaying the LED J; 3 seconds after the last correc-
tion, LED K shuts off and LED J comes back on.
LED L Impedance
Adjustment -9,9 ÷ +9,9.
In all MIG programs the display P shows a number.
Zero is the manufacturer setting, if the number is set
to negative impedance it decreases, and the arc
becomes harder; if it increases, the arc becomes softer.
LED A globular position
May not be selected. Active in non-pulsed synergic
MIG mode. When this occurs, it signals that the pair
of values selected for welding may create unstable, spat-
tering arcs.
LED F Hold
May not be selected. Activated in MIG, TIG, and
MMA welding and signals that the values shown
on the displays O and P (normally Ampere and Volt) are
those used in welding. Activated at the end of each wel-
ding session.
LED G Thermostat
It lights to signal that the overload cut-out has
been tripped.
LED H Safety
Signals that all buttons are locked. The operator
may adjust only the welding parameters in the AY
section.
To activate the function, first press the button AO and,
holding it down, briefly press the button I. The LED H
lights and displays that the function is active. To exit,
press the buttons AO and I again in the same way.
LED M Programs saved
This LED lights when you press the key AO (PRG).
See paragraph 3.4.1.
Display O
In all welding processes, it numerically displays the
selections made via the button E and adjusted via the
knob N.
For the welding current (LED D) it displays the Amperes
For the wire speed (LED C) it displays the meters per
minute
For the thickness (LED B) it displays the millimeters.
If no program exists within the selected settings, it
displays NO (abbreviation NO-PRG).
While preparing for operation of the cooling unit, it
displays the abbreviation H2O. It flashes the message
"OPn" if the wire feeder door is open.
In error messages it displays the abbreviation "Err".
In service functions it displays the abbreviations: H2O, SP ,
HSA, CrA, dP , Ito, rob, FAC.
Display P
In all welding processes, it numerically displays the selec-
tions made via the button I and adjusted via the knob Q.
For the welding voltage (LED J) it displays the Volts
For the arc length (LED K) it displays a number between
-9.9 and +9.9; zero is the recommended setting.
For impedance (LED L) it displays a number between -
9.9 and +9.9, zero is the recommended setting.
Within the memories it displays the program number
selected.
While preparing for operation of the cooling unit, it
displays the message OFF, On-C (continuous opera-
tion), On-A (automatic operation).
If no program exists in the selected settings, it displays
PRG (abbreviation NO-PRG).
In error messages it displays the error number.
In service functions it displays the abbreviations: OFF,
OnC, OnA. (H2O).
In the function "HSA" displays the messages OFF / On.
In double pulse functions:
-FdP reads OFF - 0.1-5
-ddP reads 0.1-3
-tdP reads 25-75
-AdP reads -9.9-9.9
In the function "CP" displays the messages - - -, SAu
and rES.
In the function "rob" displays the messages OFF, on (if
the robot interface is not inserted the display O will
show the flashing message rob).
In the function "FAc" displays the message - - -, ALL,
noP, PrG.
