seconds.
A current/voltage parameter may be restored outside
saving for both using or changing it. To restore it press
for 3 seconds key
AV, display by menas of knob AI the
number to be restored and show on display

3 seconds key
AV.
LED AZ JOB.
Shows that you are inside the saving menu of the saved
working points.
Selection key AY.
Gas Test .
When this jey is pressed gas stars flowing; to stop it press
the key again.
If the second press does not takes place the gas output
is interrupted after 30 seconds
Selection key AW.
Wire test.
Allows the wire feed with no current or voltage present.
When this key is held down, during the first 5 seconds
the wire advances at the speed of 1 meter per minute and
then the speed increases up to 8 meters per minute.
When this key is released the motor stops immediately.
5. SERVICE FUNCTIONS.
Press the key
AE, and hold it down for at least 3 seconds
to enter the submenu. Turning the knob
AI you select the
function, shown on the display
AL and turning the knob
AN you select the type of operation or the value, shown
on the display
AM. To return to the normal display, press
and release the key
AE immediately.
1- H2O (Cooling unit, optional).
Turning the knob
AN you select the type of operation:
OFF = shut off, ON
C = always on, ON A = automatic
start-up.
When the automatic mode is selected the pump begins
working immediately at each welding start command and
stops 3 minutes after the welding is completed.
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
seconds, 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
trigger 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 aluminum.
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
adjusting from 1 to 200% of the welding current, a value
adjusted 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
seconds.
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 the
AN 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 knob
AN .
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
seconds.(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.
