Before setting, it is necessary to make a short bead to
determine the speed closest to the type of welding that
you will be doing. This determines the reference speed.
To activate the function proceed as follows:
A)- Activate the function by turning knob AN until the
abbreviation On reappears on the display AM.
B)- Turn knob AI
(double pulse frequency) on the display AL. The display
AM reads the abbreviation OFF.
Turn the
knobAN to select the working frequency
(adjustment from 0.5 to 5 Hz). The selected value is shown
on the display AM.
C) Turn knobAI until the abbreviation ddP (difference in
m/min of the double pulse) is displayed.
Turn the knob AN to select the meters per minute (range
from 0.1 to 3m/min) that will be added to and subtracted
from the reference speed (default 1m/min).
D)Turn the knob
AI until the display shows the the
abbreviation tfP. This is the duration of the highest wire
speed, thus the highest current. It is expressed as a
percentage of the time gained from the Fdp frequency
DdP= 0,1÷3 m/min
tdP
= 25÷75% di
T
= 1/
Fdp
(0,5÷5 Hz)
Turn knob AN to adjust the percentage. Range between
25 and 75% (default 50%).
E)-Turn knobAI unitl the display shows the abbreviationAdP
(arc length of the highest current). Range between -9.9
and 9.9% (default 0).
When welding, check that the arc length is the same for
both currents; turn the AN knob to correct it if necessary.
Note: it is possible to weld within the double pulse
functions.
Once these adjustments have been made, to return to the
Should it be necessary to adjust the arc length of the
lowest current/lowest speed, adjust the arc length of
the reference speed. When the reference speed moves,
the previous settings must also be repeated for the new
speed.
11- PP (push-pull).
By using Push-Pull torch Art. 2003 function PPF (Push
Pull Force) is enabled which adjusts the drive torque of
the push-pull motor in order to make the wire feed linear.
The adjustment may range from 99 to -99 and is done
through knob AN.. Standard adjustment is 0.

12- Ito. (Inching time out.
The purpose is to stop the welding machine if the wire
from 5 to 50 centimeters by means of knob AN. When
this function is restored, it may be activated (On) or cut
off (Off).

qCO- (output Quality Control ).
Selects the output type of quality control reports:
ASC – (ASCII) serial output port, only unformatted text
for terminals of the Windows Hiperterminal kind.
PRN– (Printer) serial output port, for printer Art. 405.
14- UtC Time Zone Selection.
Specify a value from -12 to 12 depending on the country
where the welding machine will be used (e.g. Italy 1 = +1
h as against UTC)
15 - dSt Legal Time Selection.
(e.g. 0 Winter, 1 Summer)
16- Fac. (factory).
The purpose is to return the welding machine to the
original settings provided by the manufacturer. With the
function selected, the display AM shows noP = restores
the welding machine to the original settings disregarding
the stored programs, Prg = deletes all stored programs
and ALL = restores the welding machine to the original
settings.
To save the desired function press the button AV, the
abbreviation shown on the display AM
saved.
6 INSTALLATION
The
welding machine must be installed by skilled
personnel. All connections must be made in full compliance
with current safety laws (See CEI 26-23 - IEC/TS 62081).
6.1 PLACEMENT
The weight of the welding machine is approximately 80
Kg.
Position the unit in an area that ensures good stability, and
from entering.
6.2 ASSEMBLY
Mount the plug on the power cord, being especially
careful to connect the yellow/green conductor to the earth
pole. Make sure that the supply voltage corresponds to
the rated voltage of the welding machine.
Size the protective fuses based on the data listed on the
15
