! Only use the fume extractor to ex-
tract weld fumes. Do not use the
fume extractor to extract hot gases
(above 140 F/60 C), wood or ce-
ment dust, engine exhaust, liquid
vapors, explosive materials,
aggressive fumes (acid), fumes
from burning objects, or fumes from
cleaning, cutting, gouging, grind-
ing, painting, flame spraying, sand
blasting, or other non-welding op-
erations.
! Do not position the fume extractor
hood in any location that will allow
the weld fumes to be pulled into the
operator's breathing zone.
! Minimize cross drafts that affect
fume extraction by closing doors/
windows and/or installing weld
screens/curtains.
