Keep this manual for the safety warnings and
precautions, assembly, operating, inspection,
maintenance and cleaning procedures. Write the
product’s serial number in the back of the manual near
the assembly diagram (or month and year of purchase
if product has no number). Keep this manual and the

1. Work area safety
a. Keep work area clean and well lit. Cluttered or
dark areas invite accidents.
b. Do not operate welders in explosive
atmospheres, such as in the presence of
ammable liquids, gases or dust. Welders
create sparks which may ignite the dust or fumes.
c. Keep children and bystanders away while
operating a welder. Distractions can cause you to
lose control.
IMPORTANT SAFETY
INFORMATION
In this manual, on the labeling, and all other
information provided with this product:
This is the safety alert symbol. It is
used to alert you to potential personal
injury hazards. Obey all safety
messages that follow this symbol
to avoid possible injury or death.
DANGER indicates a hazardous situation which, if
not avoided, will result in death or serious injury.
WARNING indicates a hazardous situation which, if
not avoided, could result in death or serious injury.
CAUTION, used with the safety alert symbol,
indicates a hazardous situation which, if not
avoided, could result in minor or moderate injury.
2. Electrical safety
a. Welder plugs must match the outlet.
Never modify the plug in any way. Do not use
any adapter plugs with grounded welders.
Unmodied plugs and matching outlets will reduce
risk of electric shock.
b. Avoid body contact with grounded surfaces
such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric
shock if your body is grounded.
c. Do not expose welders to rain or wet
conditions. Water entering a welder will increase
the risk of electric shock.
d. 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.
e. When operating a welder outdoors, use an
extension cord suitable for outdoor use.
Use of a cord suitable for outdoor use reduces the
risk of electric shock.
f. If operating a welder in a damp location is
unavoidable, use a Ground Fault Circuit
Interrupter (GFCI) protected supply. Use of a
GFCI reduces the risk of electric shock.
NOTICE is used to address practices
not related to personal injury.
CAUTION, without the safety alert symbol, is used
to address practices not related to personal injury.
General Safety Warnings
WARNING Read all safety warnings and
instructions. Failure to follow the warnings and
instructions may result in electric shock, re and/
or serious injury.
Save all warnings and instructions
for future reference.

3. Personal safety
a. Stay alert, watch what you are doing and use
common sense when operating a welder.
Do not use a welder while you are tired or under
the inuence of drugs, alcohol or medication.
A moment of inattention while operating welders
may result in serious personal injury.
b. Use safety equipment. Always wear
ANSI-approved safety glasses and arc shaded,
impact safety full face shield. Safety equipment
such as NIOSH-approved respirator, heavy-duty
work gloves, non-skid safety shoes, or hearing
protection used for appropriate conditions will
reduce personal injuries.
c. 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.
d. Do not overreach. Keep proper footing and
balance at all times. This enables better control
of the welder in unexpected situations.
e. Only use safety equipment that has been
approved by an appropriate standards agency.
Unapproved safety equipment may not provide
adequate protection. Eye protection must be ANSIapproved and breathing protection must be NIOSH-
approved for the specic hazards in the work area.
4. Welder use and care
a. 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.
b. 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.
c. 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.
d. 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.
e. 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.
5. Service
a. Have your welder serviced by a qualied repair
person using only identical replacement parts.
This will ensure that the safety of the welder is
maintained.

Welder Safety Warnings
1. Maintain labels and nameplates on the
Welder. These carry important information.
If unreadable or missing, contact Harbor
Freight Tools for a replacement.
2. Maintain a safe working environment. Keep
the work area well lit. Make sure there is
adequate surrounding workspace. Always
keep the work area free of obstructions,
grease, oil, trash, and other debris.
3. Avoid unintentional starting. Make sure you are
prepared to begin work before turning on the Welder.
4. Unplug before performing maintenance. Unplug
the Welder from its electrical outlet before performing
any inspection, maintenance, or cleaning procedures.
5. Never leave the Welder unattended
while energized. Turn power off if
you have to leave the Welder.
6. Prevent eye injury and burns.
Wearing and using ANSI-approved
personal safety clothing and safety
devices reduce the risk for injury.
• Wear ANSI-approved safety impact eye
goggles underneath welding eye protection
featuring at least a number 10 shade lens
rating, such as the one included.
• Leather leggings, re resistant shoes or
boots should be worn when using this
product. Do not wear pants with cuffs, shirts
with open pockets, or any clothing that can
catch and hold molten metal or sparks.
• Keep clothing free of grease, oil, solvents,
or any ammable substances. Wear dry,
insulating gloves and protective clothing.
• Wear an approved head covering to protect
the head and neck. Use aprons, cape, sleeves,
shoulder covers, and bibs designed and
approved for welding and cutting procedures.
• When welding/cutting overhead or in conned
spaces, wear ame resistant ear plugs or
ear muffs to keep sparks out of ears.
7. Prevent accidental res.
Remove any combustible material
from the work area.
• When possible, move the work to a location well
away from combustible materials. If relocation
is not possible, protect the combustibles with
a cover made of re resistant material.
• Remove or make safe all combustible
materials for a radius of 35 feet (10 meters)
around the work area. Use a re resistant
material to cover or block all open doorways,
windows, cracks, and other openings.
• Enclose the work area with portable re
resistant screens. Protect combustible
walls, ceilings, oors, etc., from sparks
and heat with re resistant covers.
• 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
re watch, equipped with a re extinguisher,
during the cutting process and for at least one
half hour after the cutting is completed.
• 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.
• Do not dispose of hot slag in containers
holding combustible materials. Keep a re
extinguisher nearby and know how to use it.
• After spot welding, make a thorough examination
for evidence of re. Be aware that easily visible
smoke or ame may not be present for some
time after the re has started. Do not weld or
cut in atmospheres containing dangerously
reactive or ammable gases, vapors, liquids,
and dust. Provide adequate ventilation in work
areas to prevent accumulation of ammable
gases, vapors, and dust. Do not apply heat to a
container that has held an unknown substance
or a combustible material whose contents, when
heated, can produce ammable or explosive
vapors. Clean and purge containers before
applying heat. Vent closed containers, including
castings, before preheating, welding, or cutting.
