USING THE SUCTION ARM
The machine is fitted with one suction arm which must be assembled separately using the screws supplied
in the package. The arm's flange must be fixed to the plate, with pre-drilled holes, on the air cleaner.

FILTER REPLACEMENT

The replacement of the filters can vary in terms of frequency according to the type of use.
In fact, the variables to be considered are many, including:
• material to be welded (each material and each alloy produces different fumes / micro-dust);
• type of welding (each method to perform mig, tig, electrod welding, etc. have different behaviors);
• elements in contact (for example oil, grease, paint, etc. make the generated smoke more "aggressive").
Filtering is in any case indicated by a special light located on the control panel;
the same refers to a differential pressure switch that is housed inside the electri-
cal panel.
To replace the filters, it is necessary to use the special triangle wrench
(Photo) which is supplied with the machine, by means of which it is possible
to intervene on the lock of the filter inspection door.
Opening it you have direct access to the filtered section and by pulling one filter
towards the outside you can extract all the filters.
It is important to note that the filtering section may be difficult to extract due
to the gaskets present along the perimeter of the filters. These gaskets (which
are put under pressure) allow the maximum hermetic seal of the entire filtering
section and therefore give the guarantee that all the aspirated particulate is
filtered by the whole section.

MACHINE MAINTENANCE

The suction arm can rotate 360° about the central
axis during the rotation phase.
Arm closing and/or opening operations must be
carried out only from the front of the machine with
the operator facing the control panel.
The use of the suction arm outside the recommended
range may cause the machine to tip over. In fact,
when movements are carried out along the longest
side of the machine the force exercised is such as to
move the barycentre and act as a lever lifting and/
or tipping over the air cleaner in the direction of the
operator moving the arm.
