N.B. Serious damage to the equipment may result if the power source is
switched off during welding operations.

CONNECTION AND PREPARATION OF EQUIPMENT FOR GAS TUNGSTEN
ARC WELDING (TIG)
• TURN OFF WELDER BEFORE MAKING CONNECTIONS.
Connect welding accessories securely to avoid power loss or leakage of dan-
gerous gases. Carefully follow the safety regulations.
1.
Fit the required electrode and nozzle to the electrode holder (check the pro-
trusion and state of the electrode tip).
2.
Connect the earth lead connector to the positive (+) quick-connect terminal
Ref. 5 - Fig. 1 page 3) and the earth clamp to the workpiece near the weld-
ing zone.
3.
Connect the torch lead connector to quick-connection negative (-) terminal
(-) Rif. 6 - Fig. 1 page 3) .
4.
Connect the torch gas hose to the gas cylinder outlet.
5.
Press the illuminated switch to turn on the power source Ref. 1- Fig. 1 page
3) .
6.
Check that there are no gas leaks.
7.
Adjust welding current with ampere selector Ref. 2 - Fig. 1 page 3) .
Check gas delivery; turn gas cylinder knob to regulate flow.
NB: The electric welding arc is struck by lightly touching the workpiece with
the electrode (Scratch start).
CAUTION: When working outdoors or in windy conditions protect the flow
of shielding gas or it may be dispersed with resulting lack of protection for
the weld.

2.
Connect the torch lead to the positive terminal (+) Ref.5 - Fig. 1 page 3) .
Ensure that these connections are well tightened to avoid power loss and
overheating.
3.
Use control knob Ref. 2 - Fig. 1 page 3) to regulate welding current.

Illuminated switch (Ref. 1 must be ON (lamp light) before welding opera-
tions can be started.
Illumination of the yellow Ref. 3 - Fig. 1 page 3) on the front panel indi-
cates a fault which prevents the equipment from functioning.
The yellow LED indicates two fault types:
a) overheating caused by an excessively intense duty cycle. In this case,
stop welding and leave the power source switched on until the LED
switches off.
b) power supply too high/too low.
In this case, wait till the LED switches off, indicating normalisation of the
supply voltage and then resume welding.
CAUTION: Disconnect power before maintenance.
Replace unreadable labels.
Clean and tighten weld teminals.
Replace damaged gas hose.
Clean and tighten weld teminals.
Blow out the inside of the unit.
Increase frequency of cleaning when operating in dirty or dusty conditions.
N. B.: the power source is fitted with an anti-sticking device that disables
power if output short circuiting occurs or if the electrode sticks, allowing it
to be easily detached from the workpiece.
This device enters into operation when power is supplied to the generator,
even during the initial checking period, therefore any load input or short cir-
cuit that occurs during this phase is treated as a fault and will cause the out-
put power to be disabled.
