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 per-
centage of the time gained from the Fdp frequency (see
figure 3).
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
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 func-
tions.
Once these adjustments have been made, to return to the
control panel normal display briefly press key AE.
Should it be necessary to adjust the arc length of the low-
est current/lowest speed, adjust the arc length of the ref-
erence speed. When the reference speed moves, the pre-
vious 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
flows after starting with no passage of current.
The wire flow from the welding torch can be adjusted
from 5 to 50 centimeters by means of knob AN. When this
function is restored, it may be activated (On) or cut off
(Off).
13 - qC (Quality Control).
Enables Quality Control function.
Off- Function off.
On- Function on. (For this function please refer to
Manual 3300239 concerning Articles: 224.04 and
405.00).

16- Fac. (factory).
The purpose is to return the welding machine to the orig-
inal settings provided by the manufacturer. With the func-
tion 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 set-
tings.
To save the desired function press the button AV, the
abbreviation shown on the display AM will begin flashing;
after a few seconds, a sound will confirm that it has been
saved.
the 6 INSTALLATION
The welding machine must be installed by skilled per-
sonnel. 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 22
Kg.
Position the unit in an area that ensures good stability,
and efficient ventilation so as to prevent metal dust
(grinding) from entering.
6.2 ASSEMBLY
Mount the plug on the power cord, being especially care-
ful 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
technical specifications plate.
Connect the gas hose from the welding machine to the
gas cylinder pressure reducer. Mount the welding torch.
To make sure that the groove of the roller matches the
wire diameter used, open the mobile lateral side, remove
the cover CA, release the wire press roller by means of
the pressure adjusting knob BN, replace the roller and
remount the cover CA. (See fig.4).
Mount the wire coil and slip the wire into the feeder and
welding torch sheath.
Block the wire press roller with the knob BN and adjust
the pressure.
Turn on the machine.
Adjust the gas by means of key AY and then feed the wire
by means of key AW.
