4 - SPECIAL FUNCTIONS “Fx” SELECTION
The SPECIAL FUNCTIONS “Fx” that are only available in the MIG-
MAG synergic 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 CURRENT (CSC) - Sets the initial starting
current of the crater.
• CRATER START TIME (CSt) - This function defines the time
in which the current remains at the value of CRATER START
CURRENT.
• SLOPE (SLo) - The time lapse for passing from the CRATER
START CURRENT level to the welding current level and to pass
from the latter to the CRATER END CURRENT.
• CRATER END CURRENT (CEC) - Sets the final welding cur-
rent of the crater.
• CRATER END TIME (CEt) - This function defines the time in
which the current remains at the value of CRATER END CUR-
RENT.
• 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.

5 - PRE-SETTING
Before welding it is possible to set the following parameters:
E1
T1
D1
THICKNESS OF WELDED ITEM
WELDING CURRENT
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).
E2
T4
D2
ELECTRONIC INDUCTANCE
WELDING VOLTAGE (*)
ARC LENGTH ADJUSTMENT
(*) The parameter is pre-set by means of synergy and can be changed
by varying the ARC LENGTH ADJUSTMENT parameter.
