SECTION 6 − OPERATION
6-1. Controls
! 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.
1 Power Switch
Use switch to turn unit On and Off.
2 Filter Gauge
Gauge only indicates air pressure drop
across the filter. Clean or replace filter
when reading is over 4 in. w.c. (10 x 100 Pa)
or whenever air flow is too low to extract
fumes. The gauge should read between 0.1
and 0.5 in. w.c. (0.25 and 1.25 x 100 Pa) at
start-up (with a clean filter).
3 Filter Cleaning Switch
Use switch to operate filter cleaning sys-
tem. Clean or replace filter when reading is
over 4 in. w.c. (10 x 100 Pa) or whenever
air flow is too low to extract fumes. (See
Sections 7-3 and 7-4 for filter maintenance
information).
4 Particle Tray Release Lever
Use lever to release tray after cleaning filter
(Section 7-3).
5 Hood
Position the hood to minimize the effects of
cross drafts from outside air sources or
from other operations. Tilt the hood at a 45 °
angle and position it as close to the welding
arc as possible but no further than 14 in. (36
cm) from the arc.
6 Damper Control
The damper allows the user to regulate air
flow. In most cases, open damper fully (as
shown).
