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 dange-
rous gases. Carefully follow the safety regulations described in chapter 1.0.
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 wel-
ding zone.
3.
Connect the torch lead connector to quick-connection negative (-) terminal
Ref. 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.

1.
Connect the earth lead to the work piece to the negative terminal (-) (Ref. 6
- Fig. 1 page 3)
2.
Connect the torch lead to the positive terminal (+) Ref. 5 (Fig. 1 page 6).
Ensure that these connections are well tightened to avoid power loss and ove-
rheating.
3.
Use control knob Ref. 2 - Fig. 1 page 3) to regulate welding current.
4.
Illuminated switch Ref. 1 - Fig. 1 page 3) must be ON (lamp light) before
welding operations can be started.
5.
Illumination of the yellow LED Ref. 3 - Fig. 1 page 3) on the front panel
indicates a fault which prevents the equipment from functioning.

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.
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.
Disconnect power before maintenance. Service more often
Replace unreadable labels.
Clean and tighten weld teminals.
Replace damaged gas hose.
Repair or replace cracked cables and cords.
Blow out the inside of the unit. Increase frequency of cleaning when opera-
ting in dirty or dusty conditions.
