! Only use the fume extractor to ex-
tract weld fumes. Do not use the
fume extractor to extract hot gases
(above 104° F/40° C), wood or ce-
ment dust, engine exhaust, liquid
vapors, explosive
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.
1 Power Switch
Use switch to turn unit On and Off, and to
interrupt filter cleaning cycle.
2 Filter Pressure Gauge
Gauge only indicates air pressure drop
across the filter. Clean or replace filter
when Cleaning Cycle button is flashing
blue, Filter Pressure gauge reading is over
4 in. w.c., or whenever air flow is too low to
extract fumes. The gauge should read be-

tween 0.1 and 0.5 in. w.c. at start-up (with
a new filter).
3 Cleaning Cycle Button
Press button to manually operate filter
cleaning system. Button is illuminated dur-
materials,
ing cleaning cycle. Clean or replace filter
when Cleaning Cycle button is flashing
blue, Filter Pressure gauge reading is over
4 in. w.c., or whenever air flow is too low to
extract fumes. (See Sections 7-3 and 7-4
for filter maintenance information).
.
Filter cleaning cycle automatically
starts every time the machine is turned
off to maximize filter life.
4 Hood
Position the hood to minimize the effects of
cross drafts from outside air sources or
from other operations. Tilt the hood at a 30°
angle and position it as close to the welding
arc as possible; the distance from the hood
to the arc must not exceed the effective
4
1 3
length of the fume capture zone (see Sec-
tion 4-5).
.
Improper placement of the extraction
arm may affect shielding gas in the
weld zone and negatively impact weld
quality.
5 Air Control Knob
Use Air Control knob to regulate the
amount of clean air discharged from the
perimeter of the hood to create the most ef-
fective fume extraction zone for the work
environment.
Rotate knob toward Max position to expand
the size of the fume extraction zone. Higher
settings are recommended for open work
areas.
Rotate knob toward Min position to de-
crease the size of the extraction zone.
Lower settings are recommended for con-
fined work areas.
