The filler metal sticks to be used are those commonly
sold for the purpose. These sticks are made of the
same base material as the workpiece and, in the case
of copper and aluminium, contain a small percentage
(lower than 10%) of de-oxidising agents such as silicon
or magnesium.
The shielding gas commonly used due to its low cost is
argon. Helium or argon/helium mixtures can be used
especially when welding thick materials in order to
improve penetration and increase welding speed.
Gas flow rates normally vary, as current increases, from
8 to 12 l/min in the case of argon and from 14 to 24 l/min
in the case of helium.
In order to prevent oxidation the post-gas flow should
be adjusted so that the weld and the electrode have
time to cool before being exposed to the atmosphere
oxygen. This time should be around a few seconds.

Set-up

The safety rules reported in the preceding sections
should be carefully followed when setting up the
machine.
Connect the power cable to a socket with an adequate
current supply and insert the delayed line fuses with
an adequate rated value, as specified in the table of
TECHNICAL DATA (page 45).
To start up the machine follow these steps:
•
Place the unit so that the vents are clear of any
obstruction to ventilation air. Keep it in a dry place
and at a distance of at least 0.5 m from walls, shields
or anything.
In the case of MMA welding:
•
Connect the electrode holder to its socket (positive
'C2' or negative 'C1'), as requested by the type of
electrode.
•
Connect the work return lead to the free socket on
the power source and clamp it to a clean area of the
workpiece.
In case of TIG welding:
•
Connect the gas hose between the gas cylinder
(equipped with flow meter and pressure reducer)
and the torch connection; then connect the torch to
the socket on the front panel choosing either the
positive 'C2' or negative 'C1' output according to the
welding procedure to be used.
•
Connect the work return lead to the free socket on
the power source and clamp it to a clean area of the
workpiece.
