tHS Adjusts the duration of the overcurrent set to always
ensure good starts.
Can be adjusted from 0 to 100 (100=1sec).
In MIG:
TRG. Choice between 2- or 4- stages , 3 levels.
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. 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 10 to 200% of the welding current, a value
adjusted using the knob L.
Slo slope. Possibility of adjusting from 0,1 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 L.
CrC - «Crater filler» current. With the possibility of adjust-
ing from 10 to 200% of the welding current, a value
adjusted using the knob L.
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 I, 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.
HSA (Automatic Hot Start).
This function is blocked when function 3L is activated.
Once the function has been enabled using the knob L, the
operator may adjust the level of the starting current SC
(Hot Start), with the possibility of adjusting from 10 to
200% of the welding current, a value adjusted using the
knob L. The duration tSC of this current may also be
adjusted from 0.1 to 10 seconds. The switching time Slo
between the SC current and the welding current may also
be adjusted from 0.1 to 10 seconds.
CrA (final crater filler).
This function may be selected by means of key I 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 L, rotate
knob I 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.
SP (spot-welding). Selecting the function tSP (spot
time/spot welding time) adjusts the spot welding time
from 0.3 to 5 seconds. Activating the function tin (interval
time) adjusts the pause time between spot-welds, and
the time ranges from 0.3 to 5 seconds.
PrF (Pre-gas). Active in all processes. The adjustment
may range from 0 to 10 seconds. Pof (post gas). Active
in all MIG processes. The adjustment may range from 0 to
25 seconds.
Acc (soft-start). Active in all processes. The adjustment
may range from 1 to 100%. It is the wire speed,
expressed as a percentage of the speed set for the weld-
ing, before the wire touches the workpiece. This adjust-
ment is important in order to always achieve good starts.
Manufacturer setting "Au" automatic. The value can be
changed using the knob L. If, once changed, you wish to
return to the original settings, press the key V until the
abbreviation "Au" reappears on the display N.
BB (Burn-back). Active in all MIG processes. The adjust-
ment 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.
L (impedance). Active in all MIG processes. The adjust-
ment may range from 9.9 to +9.9. Zero is the manufac-
turer setting. If the number is negative, the impedance
decreases and the arc becomes harder; if increased, it
becomes softer.
Fac. (factory). The purpose is to return the welding machine
to the original settings provided by the manufacturer. After
the function is selected, the display N reads ( - - - )
To confirm the desired function, simply hold down the
button V for 3 seconds. The abbreviation shown on the
display N will begin flashing; after a few seconds, a sound
will confirm that it has been saved.
SLd. (W - Slope down Led). Active in TIG mode only
(The adjustment may range from 0 to 10).
6 INSTALLATION
The welding machine must be installed by skilled person-
nel. All connections must be made in full compliance with
current safety laws (CEI 26-23- IEC/TS 62081).
6.1 PLACEMENT
Position the equipment in an area that ensures good sta-
bility, efficient ventilation so as to prevent metal dust (i.e.,
from grinding) from entering.
7 START-UP FOR MIG WELDING WITH GAS.
Mount the plug on the power cord, being especially care-
fully 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 pro-
tective fuses based on the data listed on the technical
