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.

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 ALand 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- 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 pro-
cedure 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 adjust-
ing from 1 to 200% of the welding current, a value adjust-
ed 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 trig-
ger is pressed again the welding current connects to the
CrC . and is kept as long as the welding
third current
torch trigger is held down. When the welding torch trigger
is released welding stops.
2- SP (spot-welding).
14
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.
3- 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).
4- 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.
5- Prf (Pre-gas).
The adjustment may range from 0 to 3 seconds.
6- Pof (post-gas).
The adjustment may range from 0 to 30 seconds.
7- 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.
8- BB (Burn-back).
The adjustment may range from 4 to 250ms. serves to
adjust the length of the wire leaving the contact tip after
welding. The higher the number, the more the wire burns.
manufacturer setting «Au» automatic.
If, once changed, you wish to return to the original set-
tings, press the key AV until the abbreviation «Au» reap-
pears on the display N.
