At each power source start-up a short pump test takes
places for15 seconds.
If an insufficient presssure is detected the machine goes into
warning mode and H2O flashes on display AM.
If th elow pressure condition persists for more than 30 sec-
onds, the pump is disactivated and the machine goes to
error mode (ERR 75).
2- TRG.
Choice between 2- or 4- stages , 3 levels, the selection 2t and
4t with the selection key AU, without entering the service
functions.
2t the machine begins welding when the welding torch trig-
ger is pressed, and stops when released. 4t to begin welding
press and release the welding torch trigger; to interrupt, you
must press and release it again. 3L this procedure is active in
the synergic processes. Specially well suited to weld alu-
minum.
3 currents are available that can be used in welding by
means of the welding torch start button. The current and
the slope values are set as follows:
SC starting current (Hot Start). With the possibility of ad-
justing from 1 to 200% of the welding current, a value ad-
justed using the knob AN.
Slo slope. Possibility of adjusting from 1 to 10 seconds.
Defines the connection time between the first current SC
with the welding current and the second current with the
third current CrC ( crater filler current), a value set by means
of knob AN.
CrC - «Crater filler» current. With the possibility of adjusting
from 1 to 200% of the welding current, a value adjusted
using the knob AN.
Welding starts at the welding torch button pressure, the
named pressure will be the starting pressure SC.
This current is kept as long as the welding torch button is
held down; when the welding torch trigger is released the
first current connects to the welding current, set by means
of knob AI, and is kept as long as the welding torch button
is held down. When the welding torch trigger is pressed
again the welding current connects to the third current CrC
. and is kept as long as the welding torch trigger is held
down. When the welding torch trigger is released welding
stops.
3- SP (spot-welding).
Off/ON activates and disables the spot function.
The spot welding time tSP is set from 0.3 to 5 seconds.
The interval between two spots tIN is set from 0,3 to 5 sec-
onds.
This function is è blocked when function 3L is activated.
4- HSA (Automatic Hot Start).
This function is blocked when function 3L is activated and
works only with the synergic processes.
Once the function has been enabled using theAN knob , the
operator may adjust the level of the starting current SC (Hot
Start), with the possibility of adjusting from 1 to 200% of the
welding current, a value adjusted using the knobAN .
The duration tHS (default 130%) of this current may also be
adjusted from 0.1 to 10 seconds.) (default 0,5 sec.).
The switching time Slo between the SC current and the
welding current may also be adjusted from 0.1 to 10 sec-
onds.(default 0.5 seconds).

5- CrA (final crater filler).
This function may be selected by means of key AI and is
working during welding 2t or 4t and also in combination
with function HSA, if so requested.
After activating function «On» by means of knob AN, rotate
knob AI to display the abbreviations:
Slo = Fitting time between the welding current and the
crater filling time. Default 0.5 sec.
Range 0.1 – 10 seconds.
CrC = crater filling time expressed as a percentage of the
welding wire speed. Default 60%. Range from 10 to 200%.
TCr = duration of the filling current time. Default 0.5 sec.
Range 0.1 – 10 seconds.
6- PrF (Pre-gas).
The adjustment may range from 0 to 3 seconds.
7- Pof (post-gas).
The adjustment may range from 0 to 30 seconds.
8- Acc (soft-start ).
The adjustment may range from 0 to 100%.
It is the wire speed, expressed as a percentage of the speed
set for the welding, before the wire touches the workpiece.
This adjustment is important in order to always achieve
good starts.
Manufacturer setting «Au»: automatic.
The value can be changed using the knob AN. If, once
changed, you wish to return to the original settings,
press the key AV until the abbreviation «Au» reappears on
the display AM.
9- BB (Burn-back).
The adjustment may range from 4 to 250ms. Serves to ad-
just the length of the wire leaving the contact tip after weld-
ing. The higher the number, the more the wire burns.
Manufacturer setting «Au» automatic.
If, once changed, you wish to return to the original settings,
press the key AV until the abbreviation «Au» reappears on
the display N.
10- L (impedance).
The adjustment may range from -9.9 to +9,9. Zero is the
number set by the manufacturer:if the number is negative,
the impedance decreases and the arc becomes harder; if in-
creased, it becomes softer.
11- dP ( Double pulse, optional )
This type of welding varies the current intensity between
two levels and may be included in all synergic processes. Be-
fore setting, it is necessary to make a short bead to deter-
mine 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 ab-
breviation On reappears on the display AM.
B)- Turn knob AI fino uni tl the abbreviation FdP reappears
(double pulse frequency) on the display AL. The display AM
reads the abbreviation OFF.
Turn the knobAN to select the working frequency (adjust-
ment 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.
