4 - SPECIAL FUNCTIONS “Fx” SELECTION
The SPECIAL FUNCTIONS “Fx” that are only available in the syn-
ergic MIG-MAG and pulsed / double pulsed MIG welding process
are shown below. For all the other explanations regarding this
menu make reference to the relative paragraph.
•
PRE GAS (PrG)
- Provides an additional quantity of gas for a
defined time, before welding starts.
•
STARTING SPEED (StS)
- Regulates the speed at which the
wire approaches the workpiece. The value indicated is a percent-
age variation in relation to the factory setting value.
•
HOT START (Hot) -
Regulates the current intensity for igniting
the welding arc. The value indicated is a percentage variation
in relation to the factory setting value.
•
CRATER START CURRENT (F08)
- Sets the initial starting cur-
rent of the crater.
•
CRATER START TIME (F10)
- This function defines the time
in which the current remains at the value of CRATER START
CURRENT.
•
CRATER START SLOPE (F11)
- The time lapse for passing
from the CRATER START CURRENT level to the welding cur-
rent level.
•
CRATER END SLOPE (F12) -
Time required to go from the
welding current level to the “CRATER END CURRENT” level.
•
CRATER END CURRENT (F13)
- Sets the final welding cur-
rent of the crater.
•
CRATER END TIME (F15)
- This function defines the time in
which the current remains at the value of CRATER END CUR-
RENT.
•
SPOT WELD TIME (F07)
- The time during which spot welding
takes place after the arc is ignited, after which the arc is extin-
guished automatically.
•
STITCH WELD TIME (F05)
- Time in which the welding in tracts
is performed after the ignition of the arch, after which the arch
switches off automatically.
•
STITCH WELD PAUSE (F06)
- Time of pause between one
welding in tracts and another.
•
BURN BACK (bUb)
- Regulates the length of the wire after weld-
ing. The value indicated is a percentage variation in relation to
the factory setting value. Higher numbers correspond to more
burning of the wire.
•
POST GAS (PoG)
- Provides an additional quantity of gas for a
defined time, after welding ends.
•
DUAL PULSE DELTA CURRENT (F23) -
This function deter-
mines the positive or negative percentage variation in the peak
current, compared to the welding current set.
•
DUAL PULSE BALANCE (F25) -
This function determines the
positive or negative percentage variation in the duration of the
peak current, compared to that of the welding current.
•
DUAL PULSE FREQUENCY (F26) -
This function determines
the variation in frequency (Hz) for double pulsed mode.
•
SWITCH CURRENT (F19) -
This function determines the posi-
tive or negative variation in SWITCH current, compared to the
welding current set (only available if SWITCH is enabled in the
SETUP).
•
SWITCH ARC LENGTH (F20) -
This function determines the
variation in the SWITCH arc length, compared to the stand-
ard length (only available if SWITCH is enabled in the SETUP).

PROGRAM DEFAULT (dEF)
WARNING: If carried out, this operation resets the program
in use to the factory default settings.
To carry out the reset of the settings / parameters, proceed in the
following manner:
•
Rotate the ENCODER - A (E1) knob until both the displays read
dEF no
(see figure).
E1
•
Rotate the ENCODER - V knob (E2) until the PARAMETERS
DISPLAY - V screen (D2) reads
YES
.

E2
•
Hold the SAVE “MEM” key (T2) down for at least
2
consecu-
tive seconds.

The program in use has now been completed successfully. To
confirmation the above, the control panel of the welder performs
a short operation of MACHINE CHECK (all of the LED stay lit
simultaneously so as to verify their actual operation), the gen-
erator itself starts, having memorised the new settings and is
again ready to weld.
