FIRE HAZARDS
WARNING
FIRE OR EXPLOSION CAN CAUSE
DEATH, INJURY, AND PROPERTY
DAMAGE! To reduce risk of death,
injury, or property damage from fire or
explosion, read, understand, and follow
the following safety instructions. In
addition, make certain that anyone else
that uses this welding equipment, or is a
bystander in the welding area,
understands and follows these safety
instructions as well. REMEMBER! Arc
welding by nature produces sparks, hot
spatter, molten metal drops, hot slag,
and hot metal parts that can start fires,
burn skin, and damage eyes.
• Do not wear gloves or other clothing
that contain oil, grease, or other
flammable substances.
Do not wear flammable hair
preparations.
Do not weld in an area until it is
checked and cleared of combustible
and/or flammable materials. BE
AWARE that sparks and slag can fly
35 feet and can pass through small
cracks and openings. If work and
combustibles cannot be separated by
a minimum of 35 feet, protect against
ignition with suitable, snug-fitting, fire
resistant, covers or shields.
• Do not weld on walls until checking for
and removing combustibles touching
the other side of the walls.
• Do not weld, cut, or perform other
such work on used barrels, drums,
tanks, or other containers that had
contained a flammable or toxic
substance. The techniques for
removing flammable substances and
vapors, to make a used container safe
for welding or cutting, are quite
complex and require special education
and training.
• Do not strike an arc on a compressed
gas or air cylinder or other pressure
vessel. Doing so will create a brittle
area that can result in a violent rupture
immediately or at a later time as a
result of rough handling.
• Do not weld or cut in an area where
the air may contain flammable dust
(such as grain dust), gas, or liquid
vapors (such as gasoline).
• Do not handle hot metal, such as the
workpiece or electrode stubs, with
bare hands.
Wear leather gloves, heavy long
sleeve shirt, cuffless trousers, high-
topped shoes, helmet, and cap. As
necessary, use additional protective
clothing such as leather jacket or
5
Page 6
sleeves, fire resistant leggings, or
apron. Hot sparks or metal can lodge
in rolled up sleeves, trouser cuffs, or
pockets. Sleeves and collars should
be kept buttoned and pockets
eliminated from the shirt front.
Have fire extinguishing equipment
handy for immediate use! A portable
chemical fire extinguisher, type ABC,
is recommended.
• Wear ear plugs when welding
overhead to prevent spatter or slag
from falling into ear.
• Make sure welding area has a good,
solid, safe floor, preferably concrete or
masonry, not tiled, carpeted, or made
of any other flammable material.
• Protect flammable walls, ceilings, and
floors with heat resistant covers or
shields.
Check welding area to make sure it is
free of sparks, glowing metal or slag,
and flames before leaving the welding
area.
FUME HAZARDS
WARNING
FUMES, GASSES, AND VAPORS CAN
CAUSE DISCOMFORT, ILLNESS, AND
DEATH! To reduce risk of discomfort,
illness, or death, read, understand, and
follow the following safety instructions. In
addition, make certain that anyone else
that uses this welding equipment or is a
bystander in the welding area,
understands and follows these safety
instructions as well.
• Do not weld in an area until it is
checked for adequate ventilation as
described in ANSI standard #Z49.1. If
ventilation is not adequate to
exchange all fumes and gasses
generated during the welding process
with fresh air, do not weld unless you
(the welder) and all bystanders are
wearing air-supplied respirators.
• Do not heat metals coated with, or
that contain, materials that produce
toxic fumes (such as galvanized
6
steel), unless the coating is removed.
Make certain the area is well
ventilated, and the operator and all
bystanders are wearing air-supplied
respirators.
Do not weld, cut, or heat lead, zinc,
cadmium, mercury, beryllium, or
similar metals without seeking
professional advice and inspection of
the ventilation of the welding area.
These metals produce EXTREMELY
TOXIC fumes which can cause
discomfort, illness, and death.
• Do not weld or cut in areas that are
near chlorinated solvents. Vapors from
chlorinated hydrocarbons, such as
trichloroethylene and
perchloroethylene, can be
decomposed by the heat of an electric
arc or its ultraviolet radiation. These
actions can cause PHOSGENE, a
HIGHLY TOXIC gas to form, along
with other lung and eye-irritating
gasses. Do not weld or cut where
these solvent vapors can be drawn
into the work area or where the
ultraviolet radiation can penetrate to
areas containing even very small
amounts of these vapors.
• Do not weld in a confined area unless
it is being ventilated or the operator
(and anyone else in the area) is
wearing an air-supplied respirator.
• Stop welding if you develop
momentary eye, nose, or throat
irritation as this indicates inadequate
ventilation. Stop work and take
necessary steps to improve ventilation
in the welding area. Do not resume
welding if physical discomfort persists.

POWER SOURCE
CONNECTION
WARNING
High voltage danger from power
source! Consult a qualified
electrician for proper installation of
receptacle at the power source.
• This welder must be grounded while
in use to protect the operator from
electrical shock. If you are not sure if
your outlet is properly grounded, have
it checked by a qualified electrician.
Do not cut off the grounding prong or
alter the plug in any way and do not
use any adapters between the
welder's power cord and the power
source receptacle.
Make sure the POWER switch is OFF
then connect your welder's power cord
to a properly grounded 120 Vac, 60 Hz,
single phase, 15 amp power source. Do
not operate this welder if the source
voltage is less than 105 Vac or greater
than 132 Vac. Contact a qualified
electrician if this problem exists.
Improper performance and/or damage to
the welder will result if operated on
inadequate or excessive power.
EXTENSION CORDS
For optimum welder performance, an
extension cord should not be used
unless absolutely necessary. If
necessary, care must be taken in
selecting an extension cord appropriate
for use with your specific welder.
Select a properly grounded extension
cord that will mate directly with the ac
power source receptacle and the welder
power cord without the use of adapters.
Make certain that the extension cord is
properly wired and in good electrical
condition.
Extension cords must fit the following
wire size guidelines:
• 0-25 ft. requires #12 gauge
• Do not use an extension cord over 25
ft. in length
SELECTING THE WELDING
WIRE
This welder uses only four inch spools of
0.030 inch (0.8mm) self shielding flux-
core wire, AWS classification number
E71T-GS. Steel from 18 gauge up to
3/16 inch thick can be welded with this
wire.
NOTE:
• Metal thinner than 18 gauge cannot
be welded with this machine.
Attempting to do so will cause burn
through (blowing holes) in the metal
you are intending to weld.
• If a spool has developed heavy
oxidation, the only solution to the
problem is to discard the spool of wire.
If you have an oxidized spool of wire, do
not discard it until you have unspooled a
few turns of wire to see if the wire further
down on the spool is in usable condition,
if not, - discard the spool.
INSTALL THE WELDING
WIRE
WARNING
Electric shock can kill! Always turn the
POWER switch OFF and unplug the
welder's power cord from the ac power
source before installing wire.

.
.
Remove the nozzle and contact tip
from the end of the gun assembly.
Remove the drive tension by
unscrewing (ALL THE WAY in a
counter-clockwise direction) the
tension adjusting screw.
Unwrap the spool of wire then find
the leading end of the wire (it goes
through a hole in the outer edge of
the spool and is bent over the
9
Page 10
.
(
spool edge to prevent the wire from
unspooling) BUT DO NOT
UNHOOK IT YET.
Place the spool on the spindle in
such a manner that when the wire
comes off the spool, it will look like
the top illustration in Figure 2.

Figure 3. Drive Brake Assembly
Adjust the drive brake tension. The
purpose of the drive brake is to
cause the spool of wire to stop
turning at nearly the same moment
that wire feeding stops.
After checking to make sure that
your welder is disconnected from
the ac power source, free the
leading end of the wire from the
spool, but do not let go of it until told
to do so, or the wire will unspool
itself.
Using a wire cutter, cut the bent end
off the leading end of the wire so
that only a straight leading end
remains.
Hold the tension arm up off the
drive roller and insert the leading
end of the wire into the inlet guide
tube. Then push it across the drive
roller and into the gun assembly
about six inches.
Line the wire up in the outside
groove of the drive roller, then allow
the drive tension arm to drop onto
the drive roller.
Tighten (turn clockwise) the tension
adjusting screw until the tension
roller is applying enough force on
the wire to prevent it from slipping
out of the drive assembly.

Let go of the wire.
Plug the welder's power cord into
the ac power source. Adjust the
HEAT selection switches, on the
front of the welder, to any of the four
heat settings.
WARNING
ARC RAYS CAN INJURE EYES!
To reduce the risk of arc flash, make
certain that the welding wire, when it
finally comes out of the end of the
gun, does not touch the ground
clamp or any grounded piece of
metal. IMPORTANT! The welding
wire is carrying welding current
whenever the welder is turned on--
WHETHER THE TRIGGER IS
PULLED OR NOT!
14. Pull the trigger on the welding gun
to feed the wire through the gun
assembly.
15. When at least an inch of wire sticks
out past the end of the gun, release
the trigger.
16. Install the supplied 0.030 inch
(0.8mm) size contact tip.
17. Slide the contact tip over the wire
(protruding from the end of the
gun). Screw the contact tip into the
end of the gun and hand tighten
securely.
18. Install the nozzle on the gun
assembly.
19. Cut off the excess wire that extends
past the end of the nozzle.
20. Set the wire drive tension.
WARNING
ARC RAYS CAN INJURE EYES!
To reduce the risk of arc flash, make
certain that the wire coming out of
the end of the gun does not come in
contact with the ground clamp or any
grounded material during the drive
tension setting process or arcing will
occur.
a.
b.
Pull the trigger on the gun.
Turn the drive tension
adjustment knob clockwise,
increasing the drive tension
until the wire seems to feed
smoothly with out slipping.
NOTE: If TOO MUCH tension is
applied, the wire will slip on
the drive roller or will not be
able to be fed at all. If TOO
LITTLE tension is applied,
the spool of wire will want to
unspool itself. Readjust the
drive brake tension as
necessary to correct for
either problem.
c. Block the end of the nozzle by
holding it up against
something that doesn't
conduct electricity, such as a
block of wood or a concrete
floor, then trigger the gun
again, the wire should slip at
the drive roller. However, if the
wire bird-nests at the drive
roller, rethread the drive
system using less drive
tension and try again.
When the drive tension is set correctly,
there should be no slippage between the
wire and the drive roller. But if an
obstruction occurs along the wire feed
path, the wire should then slip on the
drive roller.

OPERATING THE WELDER
DUTY CYCLE
The duty cycle rating of a welder defines
how long the operator can weld and how
long the welder must be rested and
cooled. Duty cycle is expressed as a
percentage of 10 minutes and
represents the maximum welding time
allowed. The balance of the 10 minute
cycle is required for cooling.
Your new welder has a duty cycle rating
of 20% at the CSA rated output of 80
amps. This means that you can weld for
two (2) minutes out of 10 with the
remaining eight (8) minutes required for
cooling. (See the table 3.)

CAUTION
Do not constantly exceed the duty
cycle or damage to this welder can
result.
INTERNAL THERMAL
PROTECTION
If you exceed the duty cycle of your
welder, the HIGH/LOW switch will
illuminate, an internal thermal protector
will open and shut off all welder
functions. After cooling, the thermal
protector will automatically reset and the
welder will function normally again.
CONTROLS AND INDICATORS
WARNING
ELECTRIC SHOCK CAN KILL!
To remove the risk of electric shock,
be aware that the POWER switch,
when OFF, does not remove power
from all internal circuitry in the
welder.
The HIGH/LOW RANGE SWITCH
controls the main power to the welder
lights up when the dugy cycle has been
exceeded and selects the two main heat
ranges. When the switch is OFF, there
is still power to some areas of the
welder. When working inside the welder
or when removing panels on the welder,
make sure the welder is unplugged from
the wall outlet.
12
Page 13
The MINIMAX SELECTOR allows you
to select minimum and maximum heat
settings within the high and low ranges.
Refer to the instruction label inside the
welder's hood for suggestions on which
heat setting to use for your welding job.
PREPARATIONS FOR WELDING
An important factor in making a
satisfactory weld is preparation. This
includes studying the process and
equipment and then practice welding
before attempting to weld finished
product. An organized, safe, convenient,
comfortable, well-lighted work area
should be available to the operator. The
work area should specifically be free of
all flammables with both a fire
extinguisher and bucket of sand
available.
To properly prepare for welding, it is
necessary to:
• Prepare an organized, well lighted
work area (see Figure 4).
• Provide protection for the eyes and
skin of the operator and by-
bystanders.
• Set up the work piece and make the
ground clamp connection.
• Select the electrode.
• Adjust the heat control.
WARNING
Exposure to a welding arc is
extremely harmful to the eyes and
skin. Prolonged exposure to a
welding arc can cause blindness and
burns. Never strike an arc or begin

SETTING UP THE WORK PIECE
WELDING POSITIONS
Welding with an ac wire welder can be
done in any of three basic positions:
Flat, Horizontal, and Vertical. Flat
welding is generally easier, faster and
allows for better penetration. The heat
(amperage) selections will be affected
by the positions. Vertical welding is
usually only attempted when using a dc
welder. If possible, the work piece
should be positioned so that the bead
will run on a flat surface.
PREPARING THE JOINT
For effective welding, the surfaces to be
joined must be free of dirt, rust, scale, oil
or paint. Welding on metals not properly
cleaned will cause a brittle and porous
weld.
If the base metal pieces to be joined are
thick or heavy, it may be necessary to
bevel the edges, with a metal grinder, at
the point of contact, as in Figure 5. The
angle of the bevel should be
approximately 60 degrees.

WARNING
To help prevent eye injuries when
grinding, always wear goggles. The
grinder must also be inspected to
verify that it is in good condition.
See the chart, TYPES OF WELD
JOINTS, in Figure 6, for detailed
instructions for preparing the weld joint.
During the welding, the work pieces will
become hot and will tend to expand. The
expansion may cause the pieces to shift
from the regular position. If possible, the
work pieces should be clamped into the
position they are to occupy when the
welding is completed.
WARNING
ARC RAYS CAN INJURE EYES
AND BURN SKIN! To reduce the
risk of injury from arc rays, never
strike a welding arc until you, and all
bystanders in the welding area, have
welding helmet or shield in place and
are wearing the recommended
protective clothing. DO NOT
CONTINUE unless you have read,
understand and intend to follow the
entire SAFETY SUMMARY provided
at the front of this manual.
Ground Clamp Connection
The ground clamp connection is part of
the current circuit. A poor connection at
the ground clamp will waste power and
heat. Scrape away dirt, rust, scale, oil or
paint. Make sure the ground clamp
touches the metal.

GET TO KNOW YOUR
WELDER
Whether you have welded before or not,
it is important that you become familiar
with your new welder, its controls, and
the results achieved at different settings.
We strongly recommend that you
practice your new welder on scrap metal
trying different heat settings, base metal
thicknesses, and welding positions for
each type. By doing this you will gain a
feel for how changes in these welding
variables affect the weld.
The self taught welder learns through a
process of trial and error. The best way
to teach yourself how to weld is with
short periods of practice at regular
intervals. All practice welds should be
done on scrap metal that can be
discarded. Do not attempt to make any
repairs on valuable equipment until you
have satisfied yourself that your practice
welds are of good appearance and free
of slag or gas inclusions. What you fail
to learn through practice will be learned
through mistakes and re-welds later on.
HOLDING THE GUN
The best way to hold the welding gun is
the way that feels most comfortable to
you. While practicing to use your new
welder, experiment holding the gun in
different positions until you find the one
that seems to work best for you.
Position The Gun To The Workpiece
There are two angles of the gun nozzle
in relation to the work piece that must be
considered when welding.
1. Angle A (Figure 7) can be varied,
but in most cases the optimum
angle will be 60 degrees. The point
at which the gun handle is parallel
to the work piece. If angle A is
increased, penetration will increase.
If angle A is decreased, penetration
will decrease also.
m m m
Angle A
Figure 7. Gun Position, Angle A
.
Angle B (Figure 8) can be varied for
two reasons: to improve the ability
to see the arc in relation to the weld
puddle and to direct the force of the
arc.
I
I
Angle B
Figure 8. Gun Position, Angle B
The force of the welding arc follows a
straight line out of the end of the nozzle.
If angle B is changed, so will the
direction of arc force and the point at
which penetration will be concentrated.
On a butt weld joint, the only reason to
vary angle B from perpendicular
(straight up) to the work piece would be
to improve visibility of the weld puddle.
In this case, angle B can be varied
anywhere from zero to 45 degrees with
30 degrees working about the best.
On a fillet weld joint, the nozzle is
generally positioned in such a manner
so as to split the angle between the
horizontal and vertical members of the
weld joint. In most cases, a fillet weld
will be 45 degrees.
15
Page 16
Distance From The Workpiece
The end of the welding gun is designed
with the contact tip recessed from the
end of the nozzle and the nozzle
electrically insulated from the rest of the
gun. This permits the operator to
actually rest the nozzle on the work
piece and drag it along while welding.
This can be very helpful to beginning
welders to steady the gun, allowing the
welder to concentrate on welding
technique. If the nozzle is held off the
work piece, the distance between the
nozzle and the work piece should be 1/4
inch to 3/8 inch depending on the gauge
of the metal and the amount of
penetration desired. Moving closer to the
workpiece increases penetration.
Moving away from the workpiece
decreases penetration. The correct
distance must still be maintained, or the
arc may begin sputtering, signaling a
loss in welding performance.
LAYING A BEAD
WARNING
EXPOSURE TO A WELDING ARC
IS EXTREMELY HARMFUL TO THE
EYES AND SKIN! Prolonged
exposure to the welding arc can
cause blindness and burns. Never
strike an arc or begin welding until
you are adequately protected. Wear
flameproof welding gloves, A heavy
long sleeved shirt, cuffless trousers,
high topped shoes and a welding
helmet.
WARNING
ELECTRIC SHOCK CAN KILL! To
prevent ELECTRIC SHOCK, do not
perform any welding while standing,
kneeling, or lying directly on the
grounded work.
TYPES OF WELD BEADS
The following paragraphs discuss the
most commonly used arc welding
beads.
IMPORTANT! The wire in this welder is
always electrically energized whenever
the power is ON and will arc whenever
brought into contact with any electrically
conductive materials that the ground
clamp of the welder is connected to or
with which it is in contact. Therefore, it is
best to clip the wire back to the contact
tip so that you don't create an arc when
lining up on the seam to be welded.
Once you have the gun in position with
the wire lined up on the weld joint, cover
your face with the face shield, pull the
trigger and the arc will start. In a second
or two you will notice a weld puddle form
and the base of the bead beginning to
build. It is now time to begin to travel
with the gun. If you are just learning to
weld, travel by simply dragging the gun
in a straight line and at a steady speed
along the weld joint. Try to achieve a
weld with the desired penetration and a
bead that is fairly flat and consistent in
width.
16
Page 17
As you become more familiar with your
new welder and better at laying some
simple weld beads, you can begin to try
some different welding techniques to
improve, and add versatility to your
welding skills.
TRAVELING THE GUN
Gun travel refers to the movement of the
gun along the weld joint and is broken
into two elements: Direction and Speed.
A solid weld bead requires that the
welding gun be moved steadily and at
the right speed along the weld joint.
Moving the gun too fast, too slow, or
erratically will prevent proper fusion or
create a lumpy, uneven bead.
1. TRAVEL DIRECTION is the
direction the gun is moved along
the weld joint in relation to the weld
puddle. The gun is either PUSHED
(see Figure 9) into the weld puddle
or PULLED away from the weld
puddle.
Figure 9. Gun Travel Direction
For most welding jobs you will pull the
gun along the weld joint to take
advantage of the greater weld puddle
visibility. However, there are a few
applications where pushing the gun may
provide some advantages:
VERTICAL WELDING can be done by
starting at the top of a weld joint and
pulling the gun down toward the bottom.
However, in the event that puddle
control becomes difficult (such as the
puddle wanting to run downward),
starting a vertical weld at the bottom of a
weld joint and pushing the gun up
toward the top will help to overcome this
problem.
2. TRAVEL SPEED is the rate at which
the gun is being pushed or pulled
along the weld joint. For a fixed
heat setting, the faster the travel
speed, the lower the penetration
and the lower and narrower the
finished weld bead. Likewise, the
slower the travel speed, the deeper
the penetration and the higher and
wider the finished weld bead.
TYPES OF WELD BEADS
,
The STRINGER BEAD (Figure 10)
is formed by traveling with the gun
in a straight line while keeping the
wire and nozzle centered over the
weld joint. This is the easiest type of
bead to make and is the type you
have been using up to this point.
,
Figure 10. Stringer Weld Bead
The WEAVE BEAD (Figure 11)is
used when you want to deposit
metal over a wider space than
would be possible with a stringer
bead. It is made by weaving from
side to side while traveling with the
gun. It is best to hesitate
momentarily at each side before
weaving back the other way.
Figure 11. Weave Weld Bead
17
Page 18
WELDING POSITIONS
There are three basic welding positions:
flat, horizontal, and vertical.
.
The FLAT POSITION (Figure 12) is
the easiest of the welding positions
and is probably the one you have
been using thus far. It is best if you
can weld in the flat position if at all
possible as good results are easier
to achieve.
.
Figure 12. Flat Position Weld
The HORIZONTAL POSITION
(Figure 13) is next in difficulty level.
It is performed very much the same
as the flat weld except that angle B
(see POSITION OF THE GUN TO
THE WORK PIECE, above) is such
that the wire, and therefore the arc
force, is directed more toward the
metal above the weld joint. This is
to help prevent the weld puddle
from running downward while still
allowing slow enough travel speed
to achieve good penetration. A good
starting point for angle B is about
30 degrees DOWN from being
perpendicular to the work piece.
Figure 13. Horizontal Position Weld
.
The VERTICAL POSITION (Figure
14) is the next most difficult
position. Pulling the gun from top to
bottom may be easier for many
people, but in some instances it can
be difficult to prevent the puddle
from running downward. Pushing
the gun from bottom to top may
provide better puddle control and
allow slower rates of travel speed to
achieve deeper penetration. When
vertical welding, angle B (see
POSITION OF GUN TO THE
WORK PIECE, above) is usually
always kept at zero, but angle A will
generally range from 45 to 60
degrees to provide better puddle
control.
Figure 14. Vertical Position Weld

Page 19
MULTIPLE PASS WELDING
Butt Weld Joints. In PREPARING THE
WORK PIECE, we discussed the need
for edge preparation on thicker materials
by grinding a bevel on the edge of one
or both pieces of the metal being joined.
When this is done, a V is created,
between the two pieces of metal, that
will have to be welded closed. In most
cases more than one pass or bead will
need to be rayed into the joint to close
the V. Laying more than one bead into
the same weld joint is known as a
multiple-pass weld.
NOTE: WHEN USING SELF-
SHIELDING FLUX-CORE
WIRE it is very important to
thoroughly chip and brush
the slag off each completed
weld bead before making
another pass or the next
pass will be of poor quality.
The illustrations in Figure 15 show the
sequence for laying multiple pass beads
into a single V butt joint.
Root Pass
Pass
Figure 15. Triple Pass V Butt Joint
Most fillet weld joints, on metals of
moderate to heavy thickness, will require
multiple pass welds to produce a strong
joint. The illustrations in Figure 16 show
the sequence of laying multiple pass
beads into a T fillet joint and a lap fillet
joint.

SPECIAL WELDING
METHODS
SPOT WELDING
The purpose of a spot weld is to join
pieces of metal together with a spot of
weld instead of a continuous weld bead.
There are three methods of spot
welding: Burn-Through, Punch and Fill,
and Lap (see Figure 17). Each has
advantages and disadvantages
depending on the specific application as
well as personal preference.
PUNCHANDFILL
BURNTHROUGH
LAPSPOT
Figure 17. Spot Weld Methods
1. The BURN-THROUGH METHOD
welds two overlapped pieces of
metal together by burning through
the top piece and into the bottom
piece.
0.030 inch self-shielding flux-core wire
should not be used with the burn-
through method unless the metal is
19
Page 20
VERY thin or excessive filler metal
build-up and minimal penetration is
acceptable•
Always select the HIGH heat setting with
the burn-through method prior to making
a spot weld.
2• The PUNCH AND FILL METHOD
produces a weld with the most
finished appearance of the three
spot weld methods. In this method,
a hole is punched or drilled into the
top piece of metal and the arc is
directed through this hole to
penetrate into the bottom piece.
The puddle is allowed to fill up the
hole leaving a spot weld that is
smooth and flush with the surface of
the top piece.
Select the, heat setting, as if you were
welding the same thickness material
with a continuous bead.
3. The LAP SPOT METHOD directs
the welding arc to penetrate the
bottom and top pieces, at the same
time, right along each side of the
lap joint seam.
Select the heat setting as if you were
welding the same thickness material
with a continuous bead.
SPOT WELDING INSTRUCTIONS
•
Select the heat setting
recommended above for the
method of spot welding you intend
to use.
.
.
Hold the nozzle piece completely
perpendicular to and about 1/4 inch
off the work piece•
Pull the trigger on the gun and
release it when it appears that the
desired penetration has been
achieved.
.
.
Make practice spot welds on scrap
metal, varying the length of time
you hold the trigger, until a desired
spot weld is made.
Make spot welds on the actual work
piece at desired locations.

GENERAL MAINTENANCE
This welder has been engineered to give
many years of trouble-free service
providing that a few very simple steps
are taken to properly maintain it.
1. Keep the wire drive compartment lid
closed at all times unless the wire
needs to be changed or the drive
tension needs adjusting.
2. Keep all consumables (contact tips,
nozzles, and gun liner) clean and
replace when necessary. See
CONSUMABLE MAINTENANCE
AND TROUBLESHOOTING later in
this section for detailed information.
.
.
Replace power cord, ground cable,
ground clamp, or gun assembly
when damaged or worn.
Periodically clean dust, dirt, grease,
etc. from your welder. Every six
months or as necessary, remove
the side panels from the welder and
air-blow any dust and dirt that may
have accumulated inside the
welder.
WARNING
ELECTRIC SHOCK CAN KILL! To
reduce the risk of electric shock,
always unplug the welder from its ac
power source before removing side
panels.
MAINTENANCE AND CLEANING
IT IS VERY IMPORTANT TO MAINTAIN
THE CONSUMABLES TO AVOID THE
NEED FOR PREMATURE
REPLACEMENT OF THE GUN
ASSEMBLY.
CAUTION
KEEP THE NOZZLE CLEAN!
During the welding process, spatter
and slag will build up inside the
nozzle and must be cleaned out
periodically. Failure to clean and/or
replace the nozzle in a timely
fashion WILL CAUSE DAMAGE TO
THE FRONT-END OF THE GUN
ASSEMBLY, which is NOT
REPLACEABLE. The results of the
inaction will REQUIRE THE
REPLACEMENT OF THE ENTIRE
GUN ASSEMBLY.
1. Stop welding and clean any
accumulated slag or spatter from
the nozzle every 5 to 10 minutes of
welding time.
2. When welding overhead, if any
molten metal drips from the weld
puddle and falls into the nozzle,
STOP WELDING IMMEDIATELY
and clean the nozzle.
.
If the slag cannot be thoroughly
cleaned from the nozzle, REPLACE
THE NOZZLE!
Failure to keep the nozzle adequately
cleaned can result in the following
problems:
A SHORTED nozzle results when
spatter buildup bridges the insulation in
the nozzle allowing welding current to
flow through it as well as the contact tip.
When shorted, a nozzle will steal
welding current from the wire whenever
it contacts the grounded work piece.
This causes erratic welds and reduced
penetration. In addition, a shorted nozzle
overheats the end of the gun which can
DAMAGE the front-end of the gun.
TESTING FOR A SHORTED
NOZZLE
Arcing between the nozzle and the work
piece ALWAYS means the nozzle is
shorted, but this can be hard to detect
through the lens of a welding helmet.
The following testing method is another
way to tell if a nozzle is shorted.
With the welder unplugged from the ac
power source, touch the probes of an
ohmmeter or continuity tester to the end
of the contact tip and the outside of the
21
Page 22
nozzle. If there is any continuity at all,
the nozzle IS shorted. Clean or replace
as needed.
The following paragraphs describe the
procedures required to maintain and
troubleshoot your welder.
MAINTAINING THE
WELDER
Except for internal and external
cleaning, cleaning the nozzle, and
occasionally retightening screws, there
is no periodic maintenance
recommended for your welder.
