Protect yourself and others from injury — read, follow, and save these important safety precautions and operating instructions.
1-1. Symbol Usage
DANGER! − Indicates a hazardous situation which, if
not avoided, will result in death or serious injury. The
possible hazards are shown in the adjoining symbols
or explained in the text.
Indicates a hazardous situation which, if not avoided,
could result in death or serious injury. The possible
hazards are shown in the adjoining symbols or ex-
plained in the text.
NOTICE − Indicates statements not related to personal injury.
Indicates special instructions.
This group of symbols means Warning! Watch Out! ELECTRIC
SHOCK, MOVING PARTS, and HOT PARTS hazards. Consult sym-
bols and related instructions below for necessary actions to avoid the
hazards.
1-2. Fume Extraction Hazards
The symbols shown below are used throughout this manual
to call attention to and identify possible hazards. When you
see the symbol, watch out, and follow the related instructions
to avoid the hazard. The safety information given below is
only a summary of the more complete safety information
found in the Safety Standards listed in Section 1-6. Read and
follow all Safety Standards.
Only qualified persons should install, operate, maintain, and
repair this equipment. A qualified person is defined as one
who, by possession of a recognized degree, certificate, or
professional standing, or who by extensive knowledge, train-
ing and experience, has successfully demonstrated ability to
solve or resolve problems relating to the subject matter, the
work, or the project and has received safety training to recog-
nize and avoid the hazards involved.
During operation, keep everybody, especially children, away.
FUME EXTRACTOR MISUSE can be hazardous.
Welding produces fumes and gases. Breathing
these fumes and gases can be hazardous to your
health. Combustible materials can ignite and cause
fire and explosion.
Read and follow these instructions and the safety labels
carefully. The fume extractor helps protect the user from specific
airborne contaminants but must be used correctly to be fully
effective. Have an industrial hygienist test the air in your facility to
ensure the fume extractor provides adequate protection from
contaminants in your environment. If you have questions about the
extractor, see equipment label and consult your Safety Director
and a certified Industrial Hygienist.
Follow all applicable ANSI, OSHA, CSA, UL, and other regulatory
guidelines pertaining to the use of fume extractors and the
recirculation of filtered air.
Portions of fume collection equipment, including the clean- and
dirty-air plenums, can be considered OSHA Confined Spaces. Refer
to the appropriate OSHA regulations to determine if a specific
installation is a confined space and if a permit program is required.
Do not use the fume extractor without an approved and properly
installed spark guard unless the unit is designed and intended to be
used without one. Without the spark guard, welding sparks can
ignite a non-fire retardant filter or fume collected on the filter, or
damage the filter and allow unfiltered air into the breathing zone.
Do not allow sparks or any burning materials to enter the hood or
duct of the fume extractor.
Only use the fume extractor to extract weld fumes. Do not use the
fume extractor to extract hot gases (above 140 ° F/60 ° C) wood or
cement dust, engine exhaust, liquid vapors, explosive materials,
aggressive fumes (acid), fumes from burning objects, or fumes
from cleaning, cutting, gouging, grinding, painting, flame spraying,
sand blasting, or other non − welding operations.
Fumes from some welding operations can be combustible. Do not
install or operate fume extractor where combustible weld fumes
can be present unless a fire/and/or explosion protection system is
present that has been selected and approved by a qualified person
familiar with applicable codes and fire/explosion protection
systems.
Use the fume extractor only in atmospheres for which it is
recommended. Do not use the extractor where contaminant levels
are unknown or are immediately dangerous to life, or where the
contaminant levels exceed the fume extractor specifications.
Do not weld until you are sure the fume extractor is correctly
assembled and working properly.
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.
Before each use, inspect the fume extractor for damage and verify
it operates properly.
Dangerous contaminants may not smell or be visible. Leave the
area immediately if you notice the following:
a. Breathing becomes difficult.
b. You experience dizziness, impaired vision, or eye, nose, or
mouth irritation.
c. The equipment is damaged.
d. Air flow decreases or stops.
e. If you think the equipment is not supplying adequate
protection.
Do not repair, modify, or disassemble the fume extractor or use
with parts or accessories not supplied by the manufacturer. Use
only approved components from the manufacturer.
Replace damaged or plugged filter. Allow cooling period before
inspecting or replacing filter, or cleaning particle tray and spark guard.
Do not wash or reuse filter, or clean filter by tapping or with
compressed air, unless specifically instructed by the manufacturer in
the Owner’s Manual (filter element can be damaged). Do not breathe
the particles collected by the fume extractor. Wear approved safety
equipment (respirator, gloves, long sleeve shirt) when performing filter
maintenance. Dispose of used filter element and collected particles
according to local, state, and federal requirements.
Read and understand the Safety Data Sheets (SDSs) and the
manufacturer’s instructions for adhesives, coatings, cleaners,
consumables, coolants, degreasers, fluxes, and metals.
The fume extractor must be used with the extraction arm, hoses,
filter, and other components recommended by the manufacturer.
Touching live electrical parts can cause fatal shocks
or severe burns. The input power circuit and machine
internal circuits are also live when power is on.
Incorrectly installed or improperly grounded equip-
ment is a hazard.
ELECTRIC SHOCK can kill.
Do not touch live electrical parts.
Disconnect input power before installing or servicing this equip-
ment. Lockout/tagout input power according to OSHA 29 CFR
1910.147 (see Safety Standards).
Properly install, ground, and operate this equipment according to
its Owner’s Manual and national, state, and local codes.
Always verify the supply ground − check and be sure that input
power cord ground wire is properly connected to ground terminal in
disconnect box or that cord plug is connected to a properly
grounded receptacle outlet.
Frequently inspect input power cord and ground conductor for
damage or bare wiring – replace immediately if damaged – bare
wiring can kill.
