•
Connect the earth cable to the Positive output terminal on the front of the unit.
•
Connect the Tig Torch to the Negative output terminal on the front of the unit.
•
Connect the torch trigger plug and the gas hose to the corresponding connectors on the front panel
(use only Argon)
•
Power the unit ON. The display views the screen of the last welding process performed by the unit.
Mode Key -
Press the Mode Key till the TIG Welding Screen is viewed on the display.
The TIG welding processes that may be selected
are:
NORMAL
Continuous TIG welding:
2 stroke welding;
4 stroke welding with possible regulation of
Slope Up, Slope Down, final current and post
gas. This mode of welding is suggested to weld
thick metal sheets.
PULSED
Pulsed TIG welding:
2 stroke
4 stoke welding with possible regulation of Pulse
frequency, , I max, I min, Slope Up, Slope
Down, final current and post gas. This mode of
welding is suggested to weld thin metal sheets
and for precision works. The low heat injection
reduces the workpiece deformation granting
high quality weldings.
Tig Function Setup Key -
Press the Setup Key - 3 - in TIG mode to access the parameters' setup screen. Use the Right Regulation
Knob - 5 - to select 2 or 4 Stroke Welding.

Figure 5
Use the Setup Key - 3 - to run through the parameters and adjust their values by turning the Right regu-
lation Knob - 5 -.
Slope Up
Regulation of the time needed by the welding current to reach the set value (0 – 10 Sec)
Slope Down Regulation of the time needed by the welding current to reach the final current value (Crater
Filler 0 – 20 Sec)
Final Current or Crater Filler (active only for 4 Stroke Welding) Regulation of the Final Current Value or
Crater Filler (5 amps to 200 amps)
Post Gas
Regulation of the gas outflow time at the end of welding (0 – 5 Sec.)
Use the Mode Key - 1 - to go back to the TIG main screen after desired parameters are adjusted.
To save and recall later these parameters use the Prog Save & Recall Key - 4 -. Refer to paragraph 11.0.
Pulse frequency, , I max and I min values are adjustable by the Pulsed TIG Welding Menu.

2 Stroke In Manual Welding Mode the unit will weld continuously while
the torch trigger is depressed (Welding ON). Releasing the torch trigger
will interrupt welding immediately (Welding OFF).
4 Stroke In Automatic Welding Mode the welding process is performed
as follows:
• first torch trigger depression (Welding ON as current is fed, Slope Up
as set till the set current value is reached)
• first torch trigger release, welding continues.
• second torch trigger depression (Slope down and Final Current)
5
• second torch trigger release (Arc OFF and Post Gas)
