MAINTENANCE
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.
Page 4
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.
For technical questions, please call 1-800-444-3353.
Item 68887
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 Welder 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.
SETUP
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.
SAFETY
Operation Specific Safety Information
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.
If unreadable or missing, contact
Harbor Freight Tools for a replacement.

Grounding
SAFETY
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. Have a plug installed by a certified electrician. 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.
Grounded Welders
SETUP
1. The grounding prong in the plug is connected
through the green wire inside the cord 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.
2. The Welder must be plugged into an appropriate
outlet, properly installed and grounded in
accordance with all codes and ordinances.
Extension Cords
BASIC WELDING
1. If an extension cord is used, it must have
the following wire size: up to 30 feet, use
10 AWG size wire; 30 to 50 feet, use 8 AWG
wire; Over 50 feet, use 6 AWG wire.
2. As the distance from the supply outlet increases,
you must use a heavier gauge extension cord.
Using extension cords with inadequately sized
wire causes a serious drop in voltage, resulting
in loss of power and possible Welder damage.
3. The smaller the gauge number of the wire,
the greater the capacity of the cord. For
example, a 14 gauge cord can carry a
higher current than a 16 gauge cord.
4. When using more than one extension cord to
make up the total length, make sure each cord
contains at least the minimum wire size required.
5. If you are using one extension cord for more than
one welder, add the nameplate amperes and use the
sum to determine the required minimum cord size.
6. If you are using an extension cord outdoors, make
sure it is marked with the suffix “W-A” (“W” in
Canada) to indicate it is acceptable for outdoor use.
7. Make sure the extension cord is properly wired
and in good electrical condition. Always replace
a damaged extension cord or have it repaired
by a qualified electrician before using it.
WELDING TIPS
8. Protect the extension cords from sharp objects,
excessive heat, and damp or wet areas.

Duty Cycle (Duration of Use)
BASIC WELDING
Avoid damage to the Welder by not welding
for more than the prescribed duty cycle time.
The Duty Cycle defines the number of minutes, within
a 10 minute period, during which a given welder can
produce a particular welding current without overheating.
For example, this Welder with a 20% duty cycle at
rated output (90 A) must be allowed to rest for at
least 8 minutes after every 2 minutes of continuous weld.
Failure to carefully observe duty cycle limitations
can easily over‑stress a welder’s power generation
system contributing to premature welder failure. GUN
WELDING TIPS
This Welder has an internal thermal protection
90 AMP FLUX WIRE WELDER
system to help prevent this sort of over-stress.
When the unit overheats, it automatically shuts
down and the Overload Indicator lights. The Welder

Setting Up The Weld
1. Make practice welds on pieces of scrap the same
thickness as your intended workpiece to practice
technique before welding anything of value.
Clean the weld surfaces thoroughly with
a wire brush or angle grinder; there must
be no rust, paint, oil, or other materials on
the weld surfaces, only bare metal.
SAFETY
Clamps
Workpieces
2. Use clamps (not included) to hold the workpieces
in position so that you can concentrate on
proper welding technique. The distance
(if any) between the two workpieces must be
controlled properly to allow the weld to hold
both sides securely while allowing the weld
to penetrate fully into the joint. The edges of
thicker workpieces may need to be chamfered
(or beveled) to allow proper weld penetration.

SAFETY
1. Press (and hold) Trigger and contact area to
be welded with electrode wire to ignite arc.
stringer bead
weave bead
2. For a narrow weld, you can usually draw the wire in
a steady straight line.
This is called a stringer bead.
For a wider weld, draw the wire back and forth
across the joint. This is called a weave bead.
SETUP
BASIC WELDING
3. Hold Gun in one hand and the face shield
in the other. If a hands-free welding shield
(not included, see Arc Ray Safety Information
on page 3 for guidelines) is used, then
both hands can be used to control Gun.
4. Direct the welding wire straight into the joint.
This gives an angle of 90° (straight up and
down) for butt (end to end) welds, and an
angle of 45° for fillet (T-shaped) welds.

WELDING TIPS
5. The end of Gun should be tilted so that wire
is angled anywhere in‑between straight on
and 15° in the direction you are welding. The
amount of tilt is called the drag angle.
MAINTENANCE
6. The welding wire should extend no more than 1/2"
past the tip.
