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.

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 sec. 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 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)
Adjustment of the gas flow is possible
if a gas control kit has been installed
as special equipment. Press on the
the gas pre-flow and gas post-flow icons are turned
on. The gas flow is variable 4 - 26
Synergic gas flow can be activated by setting l/min to
less than 1 l. The display shows then IGC and the
current gas flow level. The synergic gas flow can be
adjusted +/- 50% by pressing the
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
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).

Pulse frequency
For TIG DC welding the range is 25-988 Hz and
for MMA DC welding the range is 25-100 Hz.

Adjustable from 10 to 90% of the pulse current.
Synergy PLUS
The machines automatically and dynamically
adjust all overall pulse parameters during
welding, when the peak welding current has been set
by encoder.
TIG tack welding TIG-A-TACK
(TIG DC HP)
The machine offers one tack welding program
to allow a quick switch from welding to tack welding.
The following features will be available:
