Fume and Gas Safety
INHALATION HAZARD:
Welding and Plasma Cutting Produce toxic fumes.
1. Exposure to welding or cutting exhaust
fumes can increase the risk of developing
certain cancers, such as cancer of the
larynx and lung cancer. Also, some diseases
that may be linked to exposure to welding
or plasma cutting exhaust fumes are:
• Early onset of Parkinson’s Disease
• Heart disease
• Ulcers
• Damage to the reproductive organs
• Inflammation of the small intestine or stomach
• Kidney damage
• Respiratory diseases such as
emphysema, bronchitis, or pneumonia
Use natural or forced air ventilation and wear
a respirator approved by NIOSH to protect
against the fumes produced to reduce the
risk of developing the above illnesses.
2. Do not use near degreasing or
painting operations.
3. Keep head out of fumes.
Do not breathe exhaust fumes.
4. Use enough ventilation, exhaust at arc, or
both, to keep fumes and gases from breathing
zone and general area. If engineering controls
are not feasible, use an approved respirator.
5. Work in a confined area only if it
is well-ventilated, or while wearing
an air-supplied respirator.
6. Have a recognized specialist in
Industrial Hygiene or Environmental Services
check the operation and air quality
and make recommendations
for the specific welding situation.
Follow OSHA guidelines for
Permissible Exposure Limits (PEL’s) and
the American Conference of Governmental
Industrial Hygienists recommendations for
Threshold Limit Values (TLV’s) for fumes and gases.
Arc Ray Safety
ARC RAYS can injure eyes and burn skin.
1. Wear ANSI-approved welding eye protection
featuring at least a number 10 shade lens rating.
2. Wear leather leggings, fire resistant shoes
or boots during use. Do not wear pants with
cuffs, shirts with open pockets, or any clothing
that can catch and hold molten metal or sparks.
3. Keep clothing free of grease, oil,
solvents, or any flammable substances.
Wear dry, insulating gloves and protective clothing.
4. Wear an approved head covering to protect
the head and neck. Use aprons, cape, sleeves,

SAFETY MAINTENANCEBASIC WELDING WELDING TIPSSETUP
Electrical Safety
ELECTRIC SHOCK can KILL.
1. Turn off, disconnect power, and
discharge electrode to ground before setting
down torch/electrode holder and before service.
2. Do not touch energized electrical parts.
Wear dry, insulating gloves. Do not touch electrode
holder, electrode, welding torch, or welding wire with
bare hand. Do not wear wet or damaged gloves.
3. Connect to grounded, GFCI-protected
power supply only.
4. Do not use near water or damp objects.
5. People with pacemakers should consult their
physician(s) before use. Electromagnetic fields
in close proximity to heart pacemaker could cause
pacemaker interference or pacemaker failure.
6. Do not expose welders to rain or wet conditions.
Water entering a welder will increase
the risk of electric shock.
7. Do not abuse the cord. Never use the cord
for carrying, pulling or unplugging the welder.
Keep cord away from heat, oil, sharp edges
or moving parts. Damaged or entangled
cords increase the risk of electric shock.
8. Do not use outdoors.
9. Insulate yourself from the workpiece and
ground. Use nonflammable, dry insulating
material if possible, or use dry rubber mats,
dry wood or plywood, or other dry insulating
material large enough to cover your full
area of contact with the work or ground.
Fire Safety
ARC AND HOT SLAG can cause fire.
1. Clear away or protect flammable objects.
Remove or make safe all combustible materials for a
radius of 35 feet (10 meters) around the work area.
Use a fire resistant material to cover
or block all open doorways, windows,
cracks, and other openings.
2. Keep ABC-type fire extinguisher near
work area and know how to use it.
3. Maintain a safe working environment.
Keep the work area well lit.
Make sure there is adequate
surrounding workspace. Keep the work area free
of obstructions, grease, oil, trash, and other debris.
4. Do not operate welders in atmospheres
containing dangerously reactive or
flammable liquids, gases, vapors, or dust.
Provide adequate ventilation in work areas
to prevent accumulation of such substances.
Welders create sparks which may ignite flammable
substances or make reactive fumes toxic.
5. If working on a metal wall, ceiling, etc.,
prevent ignition of combustibles on the
other side by moving the combustibles to a
safe location. If relocation of combustibles is
not possible, designate someone to serve as
a fire watch, equipped with a fire extinguisher,
during the cutting process and for at least one
half hour after the cutting is completed.
6. Do not weld or cut on materials having
a combustible coating or combustible
internal structure, as in walls or ceilings, without
an approved method for eliminating the hazard.
7. Do not dispose of hot slag in containers
holding combustible materials.
8. After welding, make a thorough examination
for evidence of fire. Be aware that easily
visible smoke or flame may not be present
for some time after the fire has started.
9. Do not apply heat to a container that has held
an unknown substance or a combustible
material whose contents, when heated,
can produce flammable or explosive vapors.
Clean and purge containers before applying heat.
Vent closed containers, including castings,
before preheating, welding, or cutting.

SAFETYMAINTENANCE BASIC WELDINGWELDING TIPS SETUP
Welder Use and Care
1. Do not use the welder if the switch does not turn
it on and off. Any welder that cannot be controlled
with the switch is dangerous and must be repaired.
2. Disconnect the plug from the power
source before making any adjustments,
changing accessories, or storing welders.
Such preventive safety measures reduce the
risk of starting the welder accidentally.
3. Prevent unintentional starting.
Ensure the switch is in the off-
position before connecting to power
source or moving the welder. Carrying
or energizing welders that have the
switch on invites accidents.
4. Store idle welders out of the reach of
children and do not allow persons unfamiliar
with the welder or these instructions to
operate the welder. Welders are dangerous
in the hands of untrained users.
5. Use the welder and accessories in
accordance with these instructions, taking
into account the working conditions and
the work to be performed. Use of the welder
for operations different from those intended
could result in a hazardous situation.
6. Do not use the welder for pipe thawing.
Maintenance
1. Maintain welders. Check for misalignment or
binding of moving parts, breakage of parts
and any other condition that may affect the
welder’s operation. If damaged, have the
welder repaired before use. Many accidents
are caused by poorly maintained welders.
2. Have your welder serviced by a qualified
repair person using only identical
replacement parts. This will ensure that
the safety of the welder is maintained.
3. Maintain labels and nameplates on the Welder.
These carry important information.

Grounding
TO PREVENT ELECTRIC SHOCK AND DEATH
FROM INCORRECT GROUNDING WIRE CONNECTION:
Check with a qualified electrician if you are in doubt as to whether the outlet is
properly grounded.
Do not use the Welder if the power cord or plug is damaged. If damaged, have it repaired by a service
facility before use. If the plug will not fit the outlet, have a proper outlet installed by a qualified electrician,
do not use adapter plugs.
1. The green wire inside the cord is connected to
the grounding system in the Welder. The green
wire in the cord must be the only wire connected
to the Welder’s grounding system and must
never be attached to an electrically “live” terminal.
Never leave the grounding wire disconnected
or modify the Power Cord Plug in any way.
2. Make sure the tool is connected to an outlet having
the same configuration as the plug. If the tool must
be reconnected for use on a different type of electric
circuit, the reconnection should be made by qualified
service personnel; and after reconnection, the tool
should comply with all local codes and ordinances.
Extension Cords
Do not use an extension cord on this Welder.
Replacement Cords
1. Use only one of the supplied power cords for
this Welder or an identical replacement cord.
2. Do not install a thinner or longer
cord on this Welder.
