1.
Fit the required electrode and nozzle to the electrode holder (Check the pro-
trusion and state of the electrode tip).
2.
Connect the ground cable quick connection to the positive (+) receptacle
and the clamp near the welding zone.
3.
Connect the electrode torch power cable connector to the negative quick-
connection terminal (-) and the torch push button connector to the corre-
sponding socket.
CAUTION: THE EARTH CABLE CONNECTOR AND THE TORCH POWER CABLE
CONNECTED AS ABOVE WILL RESULT IN STRAIGHT POLARITY WELDING. THIS
GENERATOR IS NOT SUITABLE FOR GTAW (TIG) WELDING WITH REVERSE
POLARITY.
4.
Insert the cylinder gas pipe into this fitting (Rif. 16 - Fig. 2 page 4) and
secure with a hose clamp.
5.
Press the illuminated switch to turn on the power source.
6.
Select the wants modality (Rif. 2-3-4 - Fig. 1 page 3).
7.
Check that there are no gas leaks.
8.
Adjust welding current with amperes selector (Rif. 7 - Fig. 1 page 3).

2-STROKE TIG WELDING
To apply 2-stroke tig welding, set the welding mode selector (Rif. 2 - Fig. 1 page
3) to position:
Adjust the slope down duration with the potentiometer (Rif. 8 - Fig. 1 page 3)
2.7
4-STROKE TIG WELDING.
To apply 4-stroke tig welding, set the welding mode selector (Ref. 3 - Fig. 1 page
3) to position:
Adjust the slope down duration with the potentiometer (Rif. 8 - Fig. 1 page 3).
2.8
GTAW WELDING (TIG) IN SPOTS
To apply spot welding, set the welding mode selector to position (Ref. 4 - Fig. 1
page 3) Timed spot welding (Point 4 - Paragraphe 3.1.1) and then set the dura-
tion by means of the potentiometer

FUNCTIONS
3.1.1 WELDING MODE SELECTOR
(Rif. 1,2,3,4 - Fig. 1 page 3) Four-position selector for selecting the required
welding mode.
1.Welding with coated electrodes. Position: for welding with
coated electrodes.
2.Position: for TIG welding with down slope regulator. The down
slope regulator is activated on release of the trigger.
3.4-stroke TIG welding. Position: the torch button operates with a 4
stroke function. When the trigger is pressed once, gas emission is
activated. Welding is then activated on release of the trigger. When
the trigger is pressed twice, the down slope regulator is activated
until the arc is shut off. Welding current is shut off on release of the
trigger.
4. Timed spot-welding. Timed spot-welding. Extremely useful
welding mode for short and repetitive welding. Welding is acti-
vated when the trigger is pressed. Spot welding intervals are
controlled by the potentiometer (Ref. 8 - Fig. 1 page 3).
3.1.2 ON INDICATOR LIGHT
(Ref. 5 - Fig. 1 page 3) This comes on when the generator is ready to
weld.
3.1.3 OVERHEATING WARNING LIGHT
The yellow LED (Ref. 6 - Fig. 1 page 3) on the front panel indicates over-
heating due to an excessive duty cycle. Interrupt welding operation; leave
the power source on until the lamp goes out, thereby signalling that tem-
perature has returned to normal.
3.1.4 AMPERAGE SELECTOR
Use control knob (Ref. 7 - Fig. 1 page 3) to regulate welding cur-
rent.
3.1.5 TIMER SLOPE /DOWN POTENTIOMETER
(Ref. 8 - Fig. 1 page 3) Regulates the down slope time from 0 to
6 seconds in 2 or 4-stroke welding mode. Regulates spot welding
interval from 0.2 to 6 seconds in spot welding mode.
3.1.6 PULSER SELECTOR / AC FREQUENCY
(Ref. 9 - Fig. 1 page 3) The power source delivers direct
current in DC mode and in position 0. The following posi-
tions set the current pulse frequency. In AC mode, the same
positions set the alternating current frequency.
3.1.7 AC/DC SELECTOR
(Rif. 10 - Fig. 1 page 3) Selection of direct or alternating current.
3.1.8 BALANCING REGULATOR
(Rif. 11- Fig. 1 page 3) Regulates ratio-between descaling
and penetration. Rotation clockwise increases penetration
and anticlockwise increases descaling. The central position
ensures the ideal compromise between descaling and pen-
etration.
3.1.9 ON - OFF SWITCH
This switch has two positions: ON and OFF.
