Final Amp [A%]
The slope-down stage is completed when
the current level has fallen to the value
stated in the Final Amp parameter. In TIG 4-times it is
possible to continue in Final Amp mode until the
trigger is released, depending from settings in user
menu. Final Amp is stated as a percentage of the
required welding current and is variable between 1-
90% of the welding current.
Spot time
The spot time in TIG is the time from the end
of slope up to beginning of slope down.
Therefore, during spot time the machine is welding
with the adjusted current. The LED flashes on and off
when the function is active.

Set welding
current
Set the timer before igniting the arc. The torch trigger,
depending from the selected torch mode can interrupt
the spot welding time. Variable 0.01 - 600 secs. The
function is disconnected when the time is set to 0 sec.
When used during tack welding, the timer can be set
from 0.01 sec to 2.5 secs (See TIG-A-TACK).
Post-flow [s]
Post-flow is the period of time for which gas
flows after the arc is extinguished and is
variable 0-20 sec.
Synergic post-flow (option) can be activated in TIG DC
by adjusting time to less than 0 secs, if the IGC kit has
been mounted. The displays shows then IGC and the
current post-flow. The synergic post-flow can be
adjusted +/- 50% by pressing the
adjusting the control knob (when the function is
active).
IGC Gas control kit (option)
Synergic adjustment of the gas flow is
possible if a gas control kit has been
installed as special equipment. Press on the
pad until the gas pre-flow and gas post-flow icons are
turned on. The gas flow is variable 4 - 26 l/min.
Synergic gas flow can be activated in TIG DC by
setting l/min to less than 4 l. The display shows then
IGC and the current gas flow level. The synergic gas
flow can be adjusted +/- 50% by pressing the
pad and ajusting the control knob (when the function is
active).
The gas valve will be completely open and the gas
adjustment is disconnected when the gas flow rate is
set to 27l.

-key pad and
turned on. The display will show X.YY where X is the
CWF unit and YY is the relative program number to be
used. Rotate the encoder to select unit/program. 0.00
is used when NO CWF must be activated. (default)
Pilot arc on/off (PLASMA welding)
Press the key pad for 6 seconds to turn ON
the pilot arc. Plasma gas will be opened
immediately to purge the torch system. Press again
the key pad to turn OFF the arc.
Pilot arc intensity (PLASMA welding)
Press the key pad to recall and regulate the
intensity of pilot arc. Amperage can be
regulated in the range of 3..20Amp in steps of
0.5Amps
Plasma gas flow (PLASMA welding)
Press the key pad to recall and regulate the
quantity of PLASMA GAS. Gas flow can be
regulated in the range of 0,1 .. 7,0 Liters in steps of
0,1L
Plasma gas slope down
(PLASMA welding)
The generator can produce a very precise gas
slope, synchronized with current slope down.It is
intended for "keyhole" applications.
Length of gas slope can be maximum the length of
current slope.Press the key pad to recall and regulate
the time for slope. Time can be regulated in steps of
0,1 sec.
Plasma gas final value
(PLASMA welding)
This is the value of PLASMA gas reached at
the end of GAS slope down. It is kept until welding
procediment is stopped. It is intended for "keyhole"
applications.Press the key pad to recall and regulate
the value. It can be regulated in the range of 0,1 .. 7,0
Liters in steps of 0,1L.

Adjustable from 0.01 to 10 sec.
Pause time
Adjustable from 0.01 to 10 sec.
Base amp
-key
Adjustable from 10 to 90% of the pulse
current.
