TIG: TIG welding
Adjusting the welding current
Select the welding current depending on the electrode,
the joint and the welding position.
Indicatively, the current to be used with the different
electrode diameter are listed in Fig.4
-i 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 the angle of
approximately 20-30 degrees in the direction in which
you are welding.
- i 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.
"ARC FORCE" adjustment**
- i This increases the intensity of the current when the
welding arc is short. Useful for increasing the
penetration of the electrodes (recommended for basic
electrodes).
Power supply indicator and fault warning light
Green LED on means that the welding machine is
powered. Red LED on: microprocessor error, switch
off the welding machine then switch it back on again.
If, after doing so, the welding machine continues to
show an error, take it to an assistance centre for a
check-up.
Thermal cut out signal
The warning light switched on means that the thermal
protection is running.
If the duty cycle "X" shown on the data plate is
exceeded, a thermal cut-out stops the machine before
any damage is caused. Wait for operation to be
resumed and, if possible, wait a few minutes more.
If the thermal cut-out continues to cut in, the welding
machine is being pushed
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 the very moment.
Ant sticking
beyond its normal
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.
**(This component may not be included with some
models).
Recommendation for use
- Only use an electrical extension when absolutely
necessary and providing it has an equal or large
section to the power.
- 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, vapour, conductive dust (e.g. iron
shavings), brackish air, caustic fumes or other agents
that could damage the metal parts and electrical
insulation.
- i The electrical 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 electronics card (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.
Disposal
Recycle waste packaging, products and accessories in
compliance with environmental rules.
Only for EC countries:
Do not dispose of waste product with domestic waste!
Comply with the provisions of directive 2012/19/EC on
waste electric and electronic equipment (WEEE) and
the national decree enforcing this directive by
collecting waste material separately and sending it to
environment- friendly recycling facilities.
Warranty
Products are guaranteed for 24 months from the date
of purchase for private end-users and 12 months for
industrial or professional end-users.
