PREPARING THE WELDING CIRCUIT TIG
• Connect the ground lead** to the welding machine and to
the piece to be welded, as close as possible to the point to
be welded.
• Connect the TIG torch** power connector to the negative
attachment on the welding machine and mount the electrode.
The torch must be fitted with a gas flow adjustment valve.
• Connect the TIG torch gas pipe to the output of the pressure
reducer mounted on an ARGON protection gas cylinder.
WELDING PROCESS: DESCRIPTION OF
CONTROLS AND SIGNALS
Once you have put the welding machine into operation,
switch it on and carry out the required adjustments.
Adjusting the welding current
Select the welding current depending on the electrode, the
joint and the welding position.
Indicatively, the currents to be used with the diferent electrode
diameters are listed in Fig. 4.
To strike the welding arc with the coated electrode, brush
it onto the piece to be welded and as soon as the arc is
struck, hold it constantly at a distance equal to the electrode
diameter and at an angle of approximately 20 - 30 degrees in
the direction in which you are welding.
To strike the welding arc with the TIG torch, make sure
that the protection gas valve is open. With a rapid, sure
movement, touch and then withdraw the electrode point from
the piece to be welded.
Heating stop indication
The warning light switched (or "HEA" display) significa che la
protezione termica è in funzione.on means that the thermal
protection is running.
If the duty cycle "X" shown on the data plate is exceeded,
a thermal cutout stops the machine before any damage is
caused. Wait for operation to be resumed and, if possible,
wait a few minutes more until the gear factor is met.
If the thermal cutout continues to cut in, the welding machine
is being pushed beyond its normal performance levels.
"Hot start"
The welding machine is fitted with an automatic device that
facilitates the striking of the arc, increasing the current only
at that very moment.
"Antisticking"
The welding machine is fitted with an automatic device that
interrupts the current a few seconds after having detected
that the electrode has stuck to the piece to be welded. In this
way the electrode will not overheat.

RECOMMENDATIONS FOR USE

• Only use an extension lead when absolutely necessary and
providing it has an equal or larger section to the power cable
and is fitted with a grounding conductor.
• Do not block the welder air intakes. Do not store the welder
in containers or on shelving that does not guarantee suitable
ventilation.
• Do not use the welder in any environment in the presence
of gas, vapours, conductive powders (e.g. iron shavings),
brackish air, caustic fumes or other agents that could damage
the metal parts and electrical insulation.
The electric parts of the welder have been treated with
protective resins. When used for the first time, smoke may
be noticed; this is caused by the resin drying out completely.
The smoke should only last for a few minutes.
MAINTENANCE
Switch off the welder and remove the plug from the
power socket before carrying out any maintenance
operations.
Extraordinary maintenance to be carried out by expert staff
or qualified electrical mechanics periodically depending on
use.
• Inspect the inside of the welder and remove any dust
deposited on the electrical parts (using compressed air) and
the electronic cards (using a very soft brush and appropriate
cleaning products).
• Check that the electrical connections are tight and that the
insulation on the wiring is not damaged.
