START-UP
:
●
Prior to work, start the extraction fan and make sure
the ventilation discharge ductwork is
functioning.
●
Set the hood into suitable position
: not more than 30 cm from the welding arc, and not less
than 20 cm
–
because the spatters might damage the hood and the suction stream could
interrupt the protection gas shield (CO
2
, argon).
●
The position
of
the
hood and the shut-off damper lever can be changed many times during
the work, so User can adjust them best to the current needs.
●
After the work is completed
– leave the extraction arm
in the
last used operational position,
when it do not cause obstacle to personnel / traffic.
●
Switch off the extraction fan
(in configuration when the arm cooperates with the extraction
system, close the shut-off damper).

Operational Use
The appliance does not require additional maintenance operations to work safely. Mainly, the
adjustment of the ERGO LUX-R extraction arm
consists in the
settings within the frictional joints.
The frictional brakes
are placed in each joint and their function is to provide the balance and
self-supporting properties
of the whole
extraction arm and to guarantee easy manoeuvring du-
ring the operation.
The adjustment of the frictional brakes is carried
out by increasing or reducing the tension
of the
nuts upon the frictional elements.
The brake adjustment
in the
following
joints ought
to be executed
in such a way that it guarantees
the stability and self-supporting
features of the ex-
traction arm (which is important
to keep the sta-
ble arm position).
Whereas,
on the other hand,
do
not
tighten up too
strongly, as this might effect in excessive opera-
tional wear
of the frictional
elements
and,
subse-
quently the joints would
get loose / released au-
tomatically.
The placement of the adjustment nuts
is illustrated
in Fig. No.1,
whereas the frictional joint is shown
in Fig. No.3.

Maximum admissible vacuum in the system cannot exceed 800 Pa.
In case of higher vacuum
of the system,
(where the ERGO LUX-R extraction arm is installed),
damage of the hoses would
occur.
