BE SURE THAT ALL INSTALLATION, OPERATION,
MAINTENANCE AND REPAIR PROCEDURES ARE
PERFORMED ONLY BY QUALIFIED INDIVIDUALS.
FOR ENGINE POWERED
EQUIPMENT.
1.a. Turn the engine off before troubleshooting
and maintenance work unless the
maintenance work requires it to be running.
1.b. Operate engines in open, well-ventilated areas or vent the engine
exhaust fumes outdoors.
1.c. Do not add the fuel near an open flame welding
arc or when the engine is running. Stop the
engine and allow it to cool before refueling to
prevent spilled fuel from vaporizing on contact
with hot engine parts and igniting. Do not spill fuel when filling
tank. If fuel is spilled, wipe it up and do not start engine until
fumes have been eliminated.
1.d. Keep all equipment safety guards, covers
and devices in position and in good repair.
Keep hands, hair, clothing and tools away
from V-belts, gears, fans and all other
moving parts when starting, operating or
repairing equipment.
1.e. In some cases it may be necessary to remove safety guards to
perform required maintenance. Remove guards only when
necessary and replace them when the maintenance requiring
their removal is complete. Always use the greatest care when
working near moving parts.
1.f. Do not put your hands near the engine fan. Do not attempt to
override the governor or idler by pushing on the throttle control
rods while the engine is running.
1.g. To prevent accidentally starting gasoline engines while turning
the engine or welding generator during maintenance work,
disconnect the spark plug wires, distributor cap or magneto wire
as appropriate.
1.h. To avoid scalding, do not remove the radiator
pressure cap when the engine is
hot.
ELECTRIC AND
MAGNETIC FIELDS MAY
BE DANGEROUS
2.a. Electric current flowing through any conductor
causes localized Electric and Magnetic Fields (EMF).
Welding current creates EMF fields around welding cables
and welding machines
2.b. EMF fields may interfere with some pacemakers, and
welders having a pacemaker should consult their physician
before welding.
2.c. Exposure to EMF fields in welding may have other health effects
which are now not known.
2.d. All welders should use the following procedures in order to
minimize exposure to EMF fields from the welding circuit:
2.d.1. Route the electrode and work cables together - Secure
them with tape when possible.
2.d.2. Never coil the electrode lead around your body.
2.d.3. Do not place your body between the electrode and work
cables. If the electrode cable is on your right side, the
work cable should also be on your right side.
2.d.4. Connect the work cable to the workpiece as close as possible to the area being welded.
2.d.5. Do not work next to welding power source.
SAFETY
Safety 02 of 04 - 5/16/2018
ELECTRIC SHOCK
CAN KILL.
3.a. The electrode and work (or ground) circuits are
electrically “hot” when the welder is on. Do
not touch these “hot” parts with your bare skin or wet clothing.
Wear dry, hole-free gloves to insulate hands.
3.b. Insulate yourself from work and ground using dry insulation.
Make certain the insulation is large enough to cover your full area
of physical contact with work and ground.
In addition to the normal safety precautions, if
welding must be performed under electrically
hazardous conditions (in damp locations or while
wearing wet clothing; on metal structures such as
floors, gratings or scaffolds; when in cramped
positions such as sitting, kneeling or lying, if there
is a high risk of unavoidable or accidental contact
with the workpiece or ground) use the following
equipment:
• Semiautomatic DC Constant Voltage (Wire) Welder.
• DC Manual (Stick) Welder.
• AC Welder with Reduced Voltage Control.
3.c. In semiautomatic or automatic wire welding, the electrode,
electrode reel, welding head, nozzle or semiautomatic welding
gun are also electrically “hot”.
3.d. Always be sure the work cable makes a good electrical
connection with the metal being welded. The connection should
be as close as possible to the area being welded.
3.e. Ground the work or metal to be welded to a good electrical (earth)
ground.
3.f. Maintain the electrode holder, work clamp, welding cable and
welding machine in good, safe operating condition. Replace
damaged insulation.
3.g. Never dip the electrode in water for cooling.
3.h. Never simultaneously touch electrically “hot” parts of electrode
holders connected to two welders because voltage
between the
two can be the total of the open circuit voltage of both
welders.
3.i. When working above floor level, use a safety belt to protect
yourself from a fall should you get a shock.
3.j. Also see It ems 6.c. and 8.
ARC RAYS CAN BURN.
4.a. Use a shield with the proper filter and cover plates to protect your
eyes from sparks and the rays of the arc when welding or
observing open arc welding. Headshield and filter lens should
conform to ANSI Z87. I standards.
4.b. Use suitable clothing made from durable flame-resistant material
to protect your skin and that of your helpers from the arc rays.
4.c. Protect other nearby personnel with suitable, non-flammable
screening and/or warn them not to watch the arc nor expose
themselves to the arc rays or to hot spatter or metal.
FUMES AND GASES
CAN BE DANGEROUS.
5.a. Welding may produce fumes and gases
hazardous to health. Avoid breathing these
fumes and gases. When welding, keep your head out of the fume.
Use enough ventilation and/or exhaust at the arc to keep fumes
and gases away from the breathing zone. When welding
hardfacing (see instructions on container or SDS)
or on lead or cadmium plated steel and other
metals or coatings which produce highly toxic
fumes, keep exposure as low as possible and
within applicable OSHA PEL and ACGIH TLV limits
using local exhaust or mechanical ventilation
unless exposure assessments indicate otherwise.
In confined spaces or in some circumstances,
outdoors, a respirator may also be required.
Additional precautions are also required when
welding
on galvanized steel.
5. b. The operation of welding fume control equipment is affected by
various factors including proper use and positioning of the
equipment, maintenance of the equipment and the specific
welding procedure and application involved. Worker exposure
level should be checked upon installation and periodically
thereafter to be certain it is within applicable OSHA PEL and
ACGIH TLV limits.
5.c. Do not weld in locations near chlorinated hydrocarbon vapors
coming from degreasing, cleaning or spraying operations. The
heat and rays of the arc can react with solvent vapors to form
phosgene, a highly toxic gas, and other irritating products.
5.d. Shielding gases used for arc welding can displace air and
cause
injury or death. Always use enough ventilation, especially in
confined areas, to insure breathing air is safe.
5.e. Read and understand the manufacturer’s instructions for this
equipment and the consumables to be used, including the
Safety Data Sheet (SDS) and follow your employer’s safety
practices. SDS forms are available from your welding
distributor or from the manufacturer.
5.f. Also see item 1.b.
SAFETY
Safety 03 of 04 - 5/16/2018
WELDING AND CUTTING
SPARKS CAN CAUSE
FIRE OR EXPLOSION.
6.a. Remove fire hazards from the welding area. If
this is not possible, cover them to prevent the welding sparks
from starting a fire. Remember that welding sparks and hot
materials from welding can easily go through small cracks and
openings to adjacent areas. Avoid welding near hydraulic lines.
Have a fire extinguisher readily available.
6.b. Where compressed gases are to be used at the job site, special
precautions should be used to prevent hazardous situations.
Refer to “Safety in Welding and Cutting” (ANSI Standard Z49.1)
and the operating information for the equipment being used.
6.c. When not welding, make certain no part of the electrode circuit is
touching the work or ground. Accidental contact can cause
overheating and create a fire hazard.
6.d. Do not heat, cut or weld tanks, drums or containers until the
proper steps have been taken to insure that such procedures
will not cause flammable or toxic vapors from substances inside.
They can cause an explosion even though they have been
“cleaned”. For information, purchase “Recommended Safe
Practices for the Preparation for Welding and Cutting of
Containers and Piping That Have Held Hazardous Substances”,
AWS F4.1 from the American Welding Society
(see address above).
6.e. Vent hollow castings or containers before heating, cutting or
welding. They may explode.
6.f. Sparks and spatter are thrown from the welding arc. Wear oil free
protective garments such as leather gloves, heavy shirt, cuffless
trousers, high shoes and a cap over your hair. Wear ear plugs
when welding out of position or in confined places. Always wear
safety glasses with side shields when in a welding area.
6.g. Connect the work cable to the work as close to the welding area
as practical. Work cables connected to the building framework or
other locations away from the welding area increase the
possibility of the welding current passing through lifting chains,
crane cables or other alternate circuits. This can create fire
hazards or overheat lifting chains or cables until they fail.
6.h. Also see item 1.c.
6.I. Read and follow NFPA 51B “Standard for Fire Prevention During
Welding, Cutting and Other Hot Work”, available from NFPA, 1
Batterymarch Park, PO box 9101, Quincy, MA 022690-9101.
6.j. Do not use a welding power source for pipe thawing.
CYLINDER MAY EXPLODE IF
DAMAGED.
7.a. Use only compressed gas cylinders containing
the correct shielding gas for the process used
and properly operating regulators designed for
the gas and pressure used. All hoses, fittings,
etc. should be suitable for the application and
maintained in good condition.
7.b. Always keep cylinders in an upright position securely chained to
an undercarriage or fixed support.
7.c. Cylinders should be located:
• Away from areas where they may be struck or subjected
to physical damage.
• A safe distance from arc welding or cutting operations
and any other source of heat, sparks, or flame.
7.d. Never allow the electrode, electrode holder or any other
electrically “hot” parts to touch a cylinder.
7.e. Keep your head and face away from the cylinder valve outlet
when opening the cylinder valve.
7.f. Valve protection caps should always be in place and hand tight
except when the cylinder is in use or connected for use.
7.g. Read and follow the instructions on compressed gas cylinders,
associated equipment, and CGA publication P-l, “Precautions for
Safe Handling of Compressed Gases in Cylinders,” available from
the Compressed Gas Association, 14501 George Carter Way
Chantilly, VA 20151.
FOR ELECTRICALLY
POWERED EQUIPMENT.
8.a. Turn off input power using the disconnect
switch at the fuse box before working on
the equipment.
8.b. Install equipment in accordance with the U.S. National Electrical
Code, all local codes and the manufacturer’s recommendations.
8.c. Ground the equipment in accordance with the U.S. National
Electrical Code and the manufacturer’s recommendations.

SAFETY
FUME EXTRACTION ARMS
As a rule of thumb, for many mild steel electrode, if the air is visibly
clear and you are comfortable, then the ventilation is generally
adequate for your work. The most accurate way to determine if the
worker exposure does not exceed the applicable exposure limit for
compounds in the fumes and gases is to have an industrial hygienist
take and analyze a sample of the air you are breathing. This is
particularly important if you are welding with stainless, hardfacing or
Special Ventilation products. All Lincoln MSDS have a maximum fume
guideline number. If exposure to total fume is kept below that
number, exposure to all fume from the electrode (not coatings or
plating on the work) will be below the TLV.
There are steps that you can take to identify hazardous substances in
your welding environment. Read the product label and material safety
data sheet for the electrode posted in the work place or in the
electrode or flux container to see what fumes can be reasonably
expected from use of the product and to determine if special
ventilation is needed. Secondly, know what the base metal is and
determine if there is any paint, plating, or coating that could expose
you to toxic fumes and/or gases. Remove it from the metal being
welded, if possible. If you start to feel uncomfortable, dizzy or
nauseous, there is a possibility that you are being overexposed to
fumes and gases, or suffering from oxygen deficiency. Stop welding
and get some fresh air immediately. Notify your supervisor and coworkers so the situation can be corrected and other workers can
avoid the hazard. Be sure you are following these safe practices, the
consumable labeling and MSDS to improve the ventilation in your
area. Do not continue welding until the situation has been corrected.
NOTE: The MSDS for all Lincoln consumables is available on Lincoln’s web-
site: www.lincolnelectric.com
Before we turn to the methods available to control welding fume
exposure, you should understand a few basic terms:
Natural Ventilation is the movement of air through the
workplace caused by natural forces. Outside, this is usually
the wind. Inside, this may be the flow of air through open
windows and doors.
Mechanical Ventilation is the movement of air through the
workplace caused by an electrical device such as a portable
fan or permanently mounted fan in the ceiling or wall.
Source Extraction (Local Exhaust) is a mechanical device
used to capture welding fume at or near the arc and filter
contaminants out of the air.
The ventilation or exhaust needed for your application depends upon
many factors such as:
• Workspace volume
• Workspace configuration
• Number of welders
• Welding process and current
• Consumables used (mild steel, hardfacing, stainless, etc.)
• Allowable levels (TLV, PEL, etc.)
• Material welded (including paint or plating)
• Natural airflow
Your work area has adequate ventilation when there is enough
ventilation and/or exhaust to control worker exposure to hazardous
materials in the welding fumes and gases so the applicable limits for
those materials is not exceeded. See chart of TLV and PEL for Typical
Electrode Ingredients, the OSHA PEL (Permissible Exposure Limit), and
the recommended guideline, the ACGIH TLV (Threshold Limit Value),
for many compounds found in welding fume.
Ventilation
There are many methods which can be selected by the user to
provide adequate ventilation for the specific application. The following
section provides general information which may be helpful in
evaluating what type of ventilation equipment may be suitable for
your application. When ventilation equipment is installed, you should
confirm worker exposure is controlled within applicable OSHA PEL
and/or ACGIH TLV. According to OSHA regulations, when welding and
cutting (mild steels), natural ventilation is usually considered
sufficient to meet requirements, provided that:
1. The room or welding area contains at least 10,000 cubic feet
(about 22' x 22' x 22') for each welder.
2. The ceiling height is not less than 16 feet.
3. Cross ventilation is not blocked by partitions, equipment, or
other structural barriers.
4. Welding is not done in a confined space.
Spaces that do not meet these requirements should be equipped with
mechanical ventilating equipment that exhausts at least 2000 CFM of
air for each welder, except where local exhaust hoods or booths, or
air-line respirators are used.
Important Safety Note:
When welding with electrodes which require special
ventilation such as stainless or hardfacing (see
instructions on container or MSDS) or on lead or
cadmium plated steel and other metals or coatings which
produce hazardous fumes, keep exposure as low as
possible and below exposure limit values (PEL and TLV)
for materials in the fume using local exhaust or
mechanical ventilation. In con ned spaces or in some
circumstances, for example outdoors, a respirator may
be required if exposure cannot be controlled to the PEL
or TLV. (See MSDS and chart of TLV and PEL for Typical
Electrode Ingredients.) Additional precautions are also
required when welding on galvanized steel.

Lincoln’s LTA 2.0 fume extraction arms telescope 3-5 ft. long,
making them ideal for small workstation or booth applications.
They are intended for use with a low-vacuum, high-volume
extraction fan.
The telescopic arm is commonly installed with a SF2400 Wallmounted Fan. Extracted air can be vented outside through the Air
Exhaust Silencer, or filtered through a Statiflex 200-M or 400-MS
Wall-Mounted Filter Unit. The Starter/Overload Switch for the
SF2400 Extraction Fan protects the motor against overcurrent.
The optional Arc Sensor/LampKit for Wall-Mounted Systems
provides a work lamp and remote, hood-mounted switches for the
lamp and extraction fan, replacing the starter/overload switch.

The recommended installation height of the wall mounting bracket
is 11.5 ft. (3500 mm). If the subject work bench is lower than the
standard height of 3.0 ft. (900 mm), it is advisable to install the
wall mounting bracket at a height of 9.8-10.6 ft. (3000-3250
mm). See Figures A.13 and A.14.
The package contains no mounting hardware for the Mount
Assembly since the required mounting hardware depends on the
wall type. The Mount Assembly can be mounted on:
• A thin brick or concrete wall (min. thickness of 4 inches/100
mm), using four threaded rods M10.
• A thick brick or concrete wall, using four cotter bolts
M10x120x60.
• Steel profile (e.g. H-profile), using four threaded rods M10.
NOTE: For central extraction systems, connec-
tion of the LTA 2.0-CW to an 8 inch duct
drop is made easier with K1657-5
Connector. See options/Accessories on
page C-1.

ATTACHING THE ROPE
Tying the counterweight too low will affect the
reach of the extraction arm.
1. Pull the arm to the longest position (See Figure A.15).
FIGURE A.15
Failure to securely knot rope could
cause injury.
2. Guide the rope through the mounting assembly (D) and over
the pulley (C), the counterweight pulley (B) and the other
small pulley (A). (See Figure A.16)
3. Keep the counterweight in the highest position, which means
just below the small pulleys. Securely fasten the rope to the
counterweight by tying a knot (E) . The rope should be
threaded through the hole in the counterweight pulley. The
knot must be large enough so the rope cannot slip back
through the hole - take measures to make sure knot does
NOT untie itself. (See Figure A.16)
