3 - SPECIAL FUNCTIONS “Fx” SELECTION
The SPECIAL FUNCTIONS “Fx” that are only available in the MIG-
MAG manual welding process are shown below. For all the other
explanations regarding this menu make reference to the relative
paragraph.
■
FIRST LEVEL MENU
• 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 percen-
tage 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 SPEED (CSS) - Sets the initial speed of the
welding wire for the crater.
• CRATER START VOLTAGE (CSu) - Sets the initial welding vol-
tage for the crater.
• CRATER START TIME (CSt) - This function defines the time
in which the current remains at the value of CRATER START
SPEED or CRATER START VOLTAGE.
• SLOPE (SLo) - Time necessary to pass from the level of CRA-
TER START SPEED or CRATER START VOLTAGE to the level
of welding current and to arrive from this level to the CRATER
END SPEED or CRATER END VOLTAGE level.
• CRATER END SPEED (CES) - Sets the final speed of the wel-
ding wire for the crater.
• CRATER END VOLTAGE (CEu) - Sets the final welding volta-
ge for the crater
• CRATER END TIME (CEt) - This function defines the time in
which the current remains at the value of CRATER END SPEED
or CRATER END VOLTAGE.
• SPOT WELD TIME (SPt) - The time during which spot welding
takes place after the arc is ignited, after which the arc is extin-
guished automatically.
• STITCH WELD TIME (SAt) - 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 (Srt) - Time of pause between one wel-
ding in tracts and another.
• BURN BACK (bub) - Regulates the length of the wire after wel-
ding. 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.
Then there is an independent parameter, SPECIAL FUNCTIONS
MENU (SPC FnC) , that provides access to the SECOND LEVEL
MENU.

SECOND LEVEL MENU
See the “Special Functions Menu (SPC FnC)” paragraph.
4 - PRE-SETTING
Before welding it is possible to set the following parameters:
E1
T1
D1
WIRE SPEED
Example: WIRE SPEED
Press the PARAMETER SELECTION - A key (T1) until the LED
that corresponds to the WIRE SPEED switches on. Turn the EN-
CODER - A knob (E1) to change the value shown on the PARA-
METER DISPLAY - A screen (D1).
