Slope-up [s]
Once the arc has been established, the welding
process enters a slope-up stage during which the
welding current is increased in linear fashion from the
value stated in the Start Amp parameter to the required
welding current. The duration of this slope-up time is
variable 0-20 sec in steps of 0.1 sec.
Second current level (only TIG 4T stroke)
Adjustable from 10 to 200% of welding current.
It is activated in four-times only by pressing and releasing
quickly the torch trigger. Please note that values bigger
than 100% generate a secondary current bigger than
welding current.
Slope-down [s]
When welding has stopped by activating the
trigger, the machine enters a slope-down stage.
During this stage current is reduced from welding current
to Final Amp over a period of time called the slope-down
time and variable 0-20 sec in steps of 0.1 sec.
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 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 0sec.
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
0-20sec.
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 -key pad and adjusting the control
knob (when the function is active).

IGC Gas control kit
Press on the -key 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 -key 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.
CWF wire program (option)
Press on the -key pad until the slope-
up and slope-down icons are 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 .. 9,0 liters in steps of 0,1 l.
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 .. 9,0 liters in
steps of 0,1 l.
Slow pulse
Is used for selection of slow pulse.
The pulse current is equal to the set
current. It is possible to adjust:
Pulse time
Adjustable from 0.01 to 10 sec.
Pause time
Adjustable from 0.01 to 10 sec.
Base amp
Adjustable from 10 to 90% of the pulse current.
