Extraction Arm

START-UP
●
Prior to beginning of the work, check if the extraction fan is functioning or make sure if the
discharge ductwork is working properly.
●
Adjust the hood into suitable position: not more than 30 cm from the welding arc, and not
less than 20 cm
– as the welding chippings (spatters) could damage the hood
and, on the
other hand, the hood suction could interrupt the protection gas shield (CO
2
, argon).
Simultaneously, the hood should capture the fume effectively,
whereby
, the extraction arm
shall not cause barrier to User.
●
By means of the shut-off damper lever adjust the intake air volume to eliminate the fume
and/or dustiness most efficiently.
●
During the operational use, the position of the hood and the damper lever can be changed
many times, so User can adjust them best to the current needs.
●
After the work is completed
– the extraction
arm can be left in the
ultimate used position (ope-
rational state), or if it causes obstacle
– set the arm into the home position.
●
Switch off the extraction fan; in case where the extraction arm works
in a ventilation system
– close the shut-off damper.
7. Operational Use
In general, the device construction guarantees a safe and reliable function without continuous
routine servicing and special handling.
If necessary
, undertake the
adjustment of the frictional joints. First take off
the hose clamp, and
and sleeve the hose off until the joint is accessible.
The bolts and nuts in the joints are fine-threaded (1 mm pitch). The adjustment of the frictional
brakes is carried out by increasing or reducing the tension of the nuts upon the frictional
elements.
In general, the brake adjustment in the following joints ought to be executed in such a way that
provides stability and self-supporting features of the extraction arm (which is important to keep
the stable arm position). Whereas,
on
the other hand,
this
cannot cause any excessive friction
resistance while User is changing the arm position.
Having completed the adjustment, tighten up the counter-nuts.
