6.3 Positioning the extraction hood
The extraction arm or extraction hood is designed in such a way that it can
be adjusted and moved easily by hand. Once it has been positioned, the
extraction hood maintains its set position of its own accord. Furthermore,
both the extraction hood and the arm can be pivoted through 360° so that
almost any position can be set. It is important that the extraction hood is
always positioned properly in order to achieve adequate capture of the
welding fumes. The correct position is shown on the following image.
• Position the extraction arm so that the extraction hood is located
approx. 25 cm diagonally above the weld.
• The extraction hood must be positioned so that it safely captures the
welding fumes, taking into account the movement of welding fumes
caused by the heat and the extraction range.
• Always move the extraction hood with respect to the weld position as
you advance.
WARNING
An incorrectly positioned extraction hood or too low an extraction
capacity do not ensure that air containing hazardous substances is
captured adequately by the extraction hood. This means hazardous
substances can enter the area where the operating personnel breathes
and cause severe damage to health.
