general Operation
this portable fume extractor is not designed to
be a substitute for a respirator or fresh-air type
respirator. Make sure that you are familiar with
the materials to be welded and know what types
of fumes will be created. Additionally, many met-
als have coatings that produce poisonous fumes
when heated. Make sure to strip coatings off at
least four inches away from the area of heat appli-
cation before welding or cutting.
this machine is not designed to collect burning
slag or molten metal from a cutting torch or a
plasma cutter operations. in these circumstances,
you must use an appropriate welding downdraft
table that will arrest all molten metal and slag.
Between welding jobs, periodically clean out the
slag catch and clean the stainless steel screen
(
Figure 11). if the type of welding changes drasti-
cally or if paint, rubberized undercoating, or other
coatings cause excessive smoke, you may have
to replace or clean filters more often in order to
maintain a satisfactory CFM.
it is always better to follow good welding practices
and remove coatings that may smoke and pos-
sibly contaminate the weld. this machine does
not save you from the task of proper workpiece
preparation.
