General Operation
this welding fume extractor is not designed
as 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 are produced. Common metals often have
coatings that produce poisonous fumes when
heated. Before welding or cutting, make sure to
strip coatings off at least four inches away from
the area of heat application.
during your welding job, periodically pay attention
to the level of caking and the color of the rolling
filter paper as seen through the window. Should the
type of welding you do change or if heavy smoking
of paint, rubberized undercoating, or coatings of
unknown material cause excessive smoke, you
may have to readjust the EXhauSting tiME
and FiltEr rolling tiME so an adequate
CFM can be maintained.
it is always better to follow good welding practices
and remove coatings that may smoke and
contaminate the weld. this machine does not
save you from the task of proper workpiece
preparation.
this fume collector is not designed to collect
smoke that contains burning slag or liquefied
metal generated from a cutting torch or a plasma
cutter. in these circumstances, you must use
the appropriate welding downdraft table that will
arrest the molten metal and slag.
