g0649 Welding downdraft table
SEcTiOn 4: OPERATiOnS
General Operation
this welding downdraft table 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. often common metals
are coated with 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 CFM and manometer and clean out the
slag drawer. Should the type of welding you do
change drastically 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 will smoke and possibly
contaminate the weld. this machine does not
save you from the task of proper workpiece
preparation.
this machine is not designed to collect smoke
that contains burning slag or liquefied metal
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.

Damage to your eyes and lungs could result
