The Above For Gasoline Engines
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.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.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.
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.
Return to Master TOCReturn to Master TOCReturn to Master TOCReturn to Master TOC
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
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 Items 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 with electrodes which require special
ventilation such as stainless or hard facing (see
instructions on container or MSDS) 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. In confined spaces or in some circumstances,
outdoors, a respirator may 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
coming from degreasing, cleaning or spraying operations.
The heat and rays of the arc can react with solvent vapors

from starting a fire. Remember that welding sparks and hot
materials from welding can easily go through small cracks
and openings to adjcent 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

SAFETY
PRÉCAUTIONS DE SÛRETÉ
Pour votre propre protection lire et observer toutes les instructions
et les précautions de sûreté specifiques qui parraissent dans ce
manuel aussi bien que les précautions de sûreté générales suivantes:
Sûreté Pour Soudage A L’Arc
1. Protegez-vous contre la secousse électrique:
a. Les circuits à l’électrode et à la piéce sont sous tension
quand la machine à souder est en marche. Eviter toujours
tout contact entre les parties sous tension et la peau nue
ou les vétements mouillés. Porter des gants secs et sans
trous pour isoler les mains.
b. Faire trés attention de bien s’isoler de la masse quand on
soude dans des endroits humides, ou sur un plancher metallique ou des grilles metalliques, principalement dans
les positions assis ou couché pour lesquelles une grande
partie du corps peut être en contact avec la masse.
c. Maintenir le porte-électrode, la pince de masse, le câble de
soudage et la machine à souder en bon et sûr état defonctionnement.
d.Ne jamais plonger le porte-électrode dans l’eau pour le
refroidir.
e. Ne jamais toucher simultanément les parties sous tension
des porte-électrodes connectés à deux machines à souder
parce que la tension entre les deux pinces peut être le total
de la tension à vide des deux machines.
f. Si on utilise la machine à souder comme une source de
courant pour soudage semi-automatique, ces precautions
pour le porte-électrode s’applicuent aussi au pistolet de
soudage.
2. Dans le cas de travail au dessus du niveau du sol, se protéger
contre les chutes dans le cas ou on recoit un choc. Ne jamais
enrouler le câble-électrode autour de n’importe quelle partie du
corps.
3. Un coup d’arc peut être plus sévère qu’un coup de soliel, donc:
6. Eloigner les matériaux inflammables ou les recouvrir afin de
prévenir tout risque d’incendie dû aux étincelles.
7. Quand on ne soude pas, poser la pince à une endroit isolé de
la masse. Un court-circuit accidental peut provoquer un
échauffement et un risque d’incendie.
8. S’assurer que la masse est connectée le plus prés possible de
la zone de travail qu’il est pratique de le faire. Si on place la
masse sur la charpente de la construction ou d’autres endroits
éloignés de la zone de travail, on augmente le risque de voir
passer le courant de soudage par les chaines de levage,
câbles de grue, ou autres circuits. Cela peut provoquer des
risques d’incendie ou d’echauffement des chaines et des
câbles jusqu’à ce qu’ils se rompent.
9. Assurer une ventilation suffisante dans la zone de soudage.
Ceci est particuliérement important pour le soudage de tôles
galvanisées plombées, ou cadmiées ou tout autre métal qui
produit des fumeés toxiques.
10. Ne pas souder en présence de vapeurs de chlore provenant
d’opérations de dégraissage, nettoyage ou pistolage. La
chaleur ou les rayons de l’arc peuvent réagir avec les vapeurs
du solvant pour produire du phosgéne (gas fortement toxique)
ou autres produits irritants.
11. Pour obtenir de plus amples renseignements sur la sûreté, voir
le code “Code for safety in welding and cutting” CSA Standard
W 117.2-1974.
PRÉCAUTIONS DE SÛRETÉ POUR
LES MACHINES À SOUDER À

REDRESSEUR
a. Utiliser un bon masque avec un verre filtrant approprié ainsi
qu’un verre blanc afin de se protéger les yeux du rayonnement de l’arc et des projections quand on soude ou
quand on regarde l’arc.
b. Porter des vêtements convenables afin de protéger la peau
de soudeur et des aides contre le rayonnement de l‘arc.
c. Protéger l’autre personnel travaillant à proximité au
soudage à l’aide d’écrans appropriés et non-inflammables.
4. Des gouttes de laitier en fusion sont émises de l’arc de
soudage. Se protéger avec des vêtements de protection libres
de l’huile, tels que les gants en cuir, chemise épaisse, pantalons sans revers, et chaussures montantes.
5. Toujours porter des lunettes de sécurité dans la zone de
soudage. Utiliser des lunettes avec écrans lateraux dans les
zones où l’on pique le laitier.

SAFETY
Electromagnetic Compatibility (EMC)
Conformance
Products displaying the CE mark are in conformity with European Community Council Directive of 15 Dec
2004 on the approximation of the laws of the Member States relating to electromagnetic compatibility,
2004/108/EC. It was manufactured in conformity with a national standard that implements a harmonized
standard: EN 60974-10 Electromagnetic Compatibility (EMC) Product Standard for Arc Welding Equipment.
It is for use with other Lincoln Electric equipment. It is designed for industrial and professional use.
Introduction
All electrical equipment generates small amounts of electromagnetic emission. Electrical emission may be
transmitted through power lines or radiated through space, similar to a radio transmitter. When emissions
are received by other equipment, electrical interference may result. Electrical emissions may affect many
kinds of electrical equipment; other nearby welding equipment, radio and TV reception, numerical controlled
machines, telephone systems, computers, etc. Be aware that interference may result and extra precautions
may be required when a welding power source is used in a domestic establishment.
Installation and Use
The user is responsible for installing and using the welding equipment according to the manufacturer’s
instructions. If electromagnetic disturbances are detected then it shall be the responsibility of the user of the
welding equipment to resolve the situation with the technical assistance of the manufacturer. In some cases
this remedial action may be as simple as earthing (grounding) the welding circuit, see Note. In other cases
it could involve construction of an electromagnetic screen enclosing the power source and the work complete with associated input filters. In all cases electromagnetic disturbances must be reduced to the point
where they are no longer troublesome.
Note: The welding circuit may or may not be earthed for safety reasons according to national
codes. Changing the earthing arrangements should only be authorized by a person who is
competent to access whether the changes will increase the risk of injury, e.g., by allowing
parallel welding current return paths which may damage the earth circuits of other equipment.
Assessment of Area
Before installing welding equipment the user shall make an assessment of potential electromagnetic problems in the surrounding area. The following shall be taken into account:
a) other supply cables, control cables, signaling and telephone cables; above, below and adjacent to the
welding equipment;
b) radio and television transmitters and receivers;
c) computer and other control equipment;
d) safety critical equipment, e.g., guarding of industrial equipment;
e) the health of the people around, e.g., the use of pacemakers and hearing aids;
f) equipment used for calibration or measurement
g) the immunity of other equipment in the environment. The user shall ensure that other equipment being
used in the environment is compatible. This may require additional protection measures;
h) the time of day that welding or other activities are to be carried out.

SAFETY
Electromagnetic Compatibility (EMC)
The size of the surrounding area to be considered will depend on the structure of the building and other
activities that are taking place. The surrounding area may extend beyond the boundaries of the premises.
Methods of Reducing Emissions
Mains Supply
Welding equipment should be connected to the mains supply according to the manufacturer’s recommendations. If interference occurs, it may be necessary to take additional precautions such as filtering of the mains
supply. Consideration should be given to shielding the supply cable of permanently installed welding equipment, in metallic conduit or equivalent. Shielding should be electrically continuous throughout its length. The
shielding should be connected to the welding power source so that good electrical contact is maintained
between the conduit and the welding power source enclosure.
Maintenance of the Welding Equipment
The welding equipment should be routinely maintained according to the manufacturer’s recommendations.
All access and service doors and covers should be closed and properly fastened when the welding equipment is in operation. The welding equipment should not be modified in any way except for those changes
and adjustments covered in the manufacturers instructions. In particular, the spark gaps of arc striking and
stabilizing devices should be adjusted and maintained according to the manufacturer’s recommendations.
Welding Cables
The welding cables should be kept as short as possible and should be positioned close together, running at
or close to floor level.
Equipotential Bonding
Bonding of all metallic components in the welding installation and adjacent to it should be considered.
However, metallic components bonded to the work piece will increase the risk that the operator could
receive a shock by touching these metallic components and the electrode at the same time. The operator
should be insulated from all such bonded metallic components.
Earthing of the Workpiece
Where the workpiece is not bonded to earth for electrical safety, not connected to earth because of its size
and position, e.g., ships hull or building steelwork, a connection bonding the workpiece to earth may reduce
emissions in some, but not all instances. Care should be taken to prevent the earthing of the workpiece
increasing the risk of injury to users, or damage to other electrical equipment. Where necessary, the connection of the workpiece to earth should be made by a direct connection to the workpiece, but in some
countries where direct connection is not permitted, the bonding should be achieved by suitable capacitance,
selected according to national regulations.
Screening and Shielding
Selective screening and shielding of other cables and equipment in the surrounding area may alleviate
problems of interference. Screening of the entire welding installation may be considered for special applica-
1
tions.

rated current and duty cycle. Length refers to the distance from the welder to the work and back to the
welder. Cable diameters are increased for long cable
lengths to reduce voltage drops.

Cable Installation
INSTALLATION
MACHINE GROUNDING
Install the welding cables to your OUTBACK® 185 as
follows. See Figure A.1 for the location of parts.
1. The gasoline engine must be OFF to install weld-
ing cables.
2. Remove the 1/2-13 flanged nuts from the output
terminals.
3. Connect the electrode holder and work cables to
the weld output terminals. Normally, the electrode
cable is connected to the positive (+) output stud.
4. Tighten the flanged nuts securely.
5. Be certain that the metal piece you are welding
(the “work”) is securely connected to the work
clamp and cable.
6. Check and tighten the connections periodically.
CAUTION
• Loose connections will cause the output studs to
overheat and the studs may eventually melt.
• Do not cross welding cables at output stud connec-
tion. Keep isolated and separate from one another.
Lincoln Electric offers a welding accessory kit with #6
welding cables. See the ACCESSORIES section of
this manual for more information.
Because this portable engine driven welder or generator creates its own power, it is not necessary to connect
its frame to an earth ground, unless the machine is
connected to premises wiring (your home, shop, etc.).
To prevent dangerous electric shock, other equipment
to which this engine driven welder supplies power,
must:
a) be grounded to the frame of the welder using a
grounded type plug
or
b) be double insulated
When this welder is mounted on a truck or trailer, the
machine grounding stud must be securely connected to the metal frame of the vehicle.
In general if the machine is to be grounded, it should
be connected with a #8 or larger copper wire to a solid
earth ground such as a metal water pipe going into the
ground for at least ten feet and having no insulated
joints, or to the metal framework of a building which
has been effectively grounded. The U.S. National
Electrical Code lists a number of alternate means of
grounding electrical equipment. A machine grounding
stud marked with the symbol is provided on the
front of the welder.
WARNING
DO NOT GROUND MACHINE TO A PIPE WHICH CARRIES EXPLOSIVE OR COMBUSTIBLE MATERIAL.
For more information on welding , see WELDINGOPERATION in the OPERATION section of this manual.

OPERATION
GENERAL DESCRIPTION
The OUTBACK® 185 is designed for commercial use
welder/generator applications. As a welder it provides
185 amps of DC constant current for welding with DC
stick electrodes. A single dial lets you select a full
range of welding output from 50 to 185 amps.
As a generator it can supply up to surge watts or continuous watts of 120 / 240 volt, single-phase AC power.
The machine is portable.
A Kohler CS 12.75 HP air cooled, OHV gasoline
engine powers the welder / generator. It has an engine
warranty of 3 years.
RECOMMENDED APPLICATIONS
Welder
The OUTBACK® 185 provides excellent constant current DC welding output for stick (SMAW) welding.
Generator
The OUTBACK® 185 gives smooth AC generator output for continuous auxiliary power usage within the
engine manufacturer’s required maintenance recommendations.
OPERATIONAL FEATURES AND
CONTROLS
DESIGN FEATURES AND
ADVANTAGES
• 185 amp DC constant current welding for stick
electrodes.
• Lightweight / portable.
• Full range, continuous welding output control with
a single knob.
• Automatic shutdown under low oil level condition.
• Hour Meter Standard.
• Surge watts or Watts of continuous 120 / 240 volt
single phase AC auxiliary power.
• Kohler CS 12.75 HP overhead cam air-cooled
gasoline engine. Smooth running, long life.
WELDING CAPABILITY
The OUTBACK® 185 rated 185 amps, 20 VDC at 10%
duty cycle on a ten-minute basis. This means that you
can load the welder to 185 amps for one minute out of
every ten-minute period. The machine is capable of
higher duty cycles at lower output currents. For example, you can load the welder to 120 amps for ten minutes out of ten for a 100% duty cycle.
The current is continuously variable from 50 to 185
amps DC. The OUTBACK® 185 can, therefore, weld
with all 3/32”, 1/8” and most 5/32” diameter Lincoln DC
electrodes.
The OUTBACK® 185 was designed for simplicity.
Therefore, it has very few operating controls. A single
dial on the control panel lets you select either welder
or generator use. For welding, the same dial selects
continuous current output over the machine’s 50 to
185 amp range.
The gasoline engine controls include a recoil starter,
choke and stop switch. See ENGINE OPERATION in
the OPERATION section of this manual for details
about starting, running, stopping, and breaking in the
gasoline engine.
LIMITATIONS
• The OUTBACK® 185 is not recommended for any
processes besides those that are normally performed using stick welding (SMAW) procedures.
• The OUTBACK® 185 is not recommended for pipe
thawing.
• During welding, generator power is limited to 100
watts, and output voltages can drop from 120 to 80
volts and 240 to 160 volts. Therefore, DO NOT
OPERATE ANY SENSITIVE ELECTRICAL EQUIPMENT WHILE YOU ARE WELDING.

When in “AUTO IDLE” ( / ) position, the
engine will run continuously and the idler operates as
follows:
• Welding
When the electrode touches the work, the welding
arc is initiated and the engine accelerates to full
speed. After welding ceases (and no auxiliary power
is being drawn), the engine will return to low idle after
approximately 10 to 14 seconds.
• Auxiliary Power
With the engine running at low idle and auxiliary
power for lights or tools is drawn (approximately 0150 watts or greater) from the receptacles, the
engine will accelerate to high speed. If no power is
being drawn from the receptacles (and not welding)
for 10-14 seconds, the idler reduces the engine
speed to low idle.

engine is running because this will cause damage to
the ring gear and/or starter motor.
Stopping the Engine
Remove all welding and auxiliary power loads and
allow engine to run for a few minutes to cool the
engine.
Break-in Period
It is normal for any engine to use larger quantities of oil
until break-in is accomplished. Check the oil level
twice a day during the break-in period (about 50 running hours). Change the oil after the first 5 hours of
operation. See the Engine Instruction Manual for further details.
CAUTION
IN ORDER TO ACCOMPLISH THIS BREAK-IN, THE
UNIT SHOULD BE SUBJECTED TO MODERATE
LOADS, WITHIN THE RATING OF THE MACHINE.
AVOID LONG IDLE RUNNING PERIODS. REMOVE
LOADS AND ALLOW ENGINE TO COOL SEVERAL
MINUTES AT LOW IDLE BEFORE SHUTDOWN.
This engine has a built in sensor which responds to low
oil level (not pressure). When activated, the system
will shut the engine down. The engine will not restart
until sufficient oil is added. Check oil level frequently
and add oil as required to the full mark on the dipstick.
DO NOT OVERFILL.
Stop the engine by placing the engine switch in the
“Off” ( ) position.

ENGINE STARTING, PROTECTION
AND BATTERY CHARGING
ENGINE STARTING
A 12 Volt battery supplies power to the rotary
run/stop/idle switch through a fuse that is located
inside the control box. There is also a lead running
from the fuse to the PC board. This is for battery
charging only.
When the switch is placed in the “Low Idle” or “High
Idle” position, a relay on the PC board is activated.
This relay activates the engine ignition system by
opening a ground lead from the engine magneto.
When the switch is held in the “Start” position, the
starter motor solenoid is activated, cranking the
engine. After the engine starts, the switch is released
and returns to the “high idle” position.
Return to Master TOCReturn to Master TOCReturn to Master TOCReturn to Master TOC
NOTE: Unshaded areas of Block Logic

OUTBACK® 185
If the battery is too low to properly power the starter
motor, the built-in recoil starter can be used to crank
the engine. (As long as the battery can produce 6 volts
or more, the engine ignition system will remain
enabled.)
NOTE: This machine will only start if there is at least 6
volts available to activate the engine ignition system. If
the battery is removed or completely dead, the engine
will not start.
ENGINE PROTECTION
The Kohler engine has a built-in oil level sensor that is
connected to an oil level module. If the oil level is low,
the ignition magneto is disabled. This will prevent the
engine from starting, or shut it down. Low oil level will
also cause a warning light on the Outback®’s control
panel to flicker for a few seconds when cranking the
engine.

Return to Section TOCReturn to Section TOCReturn to Section TOCReturn to Section TOC
AUTOMATIC IDLE SYSTEM
The Outback® 185 is equipped with an automatic
engine idle system. A solenoid is used to pull the
engine throttle to a preset low speed position when 12
volts DC is applied. When no voltage is applied, the
solenoid is released allowing the engine governor to
control the RPM.
The “high” and “auto” positions on the rotary
run/stop/idle switch control the supply of positive (+)
battery voltage to the idle solenoid. When the switch is
in the “high” position, the solenoid is shut off and the
engine will remain in high idle. When the switch is in
the “auto” position, positive (+) battery voltage is
applied to the solenoid and the negative (-) connection
is controlled by the PC board as described below.
The following explanation assumes that the rotary
switch is in the “auto” position and the engine is operating at low RPM.
Return to Master TOCReturn to Master TOCReturn to Master TOCReturn to Master TOC
NOTE: Unshaded areas of Block Logic
Diagram are the subject of discussion
OUTBACK® 185
Weld and auxiliary current are detected by a toroidal
current sensor that is connected to the PC board.
When sufficient current flows through the sensor; the
PC board detects this and immediately interrupts the
negative (-) connection to the solenoid. The solenoid
is released and the engine RPM increases to the high
setting. When the current flow stops, the PC board will
begin a time delay of about 12 seconds. If the current
flow begins again during this time delay, the solenoid
remains inactive and the engine continues to operate
at high RPM. If no current flow is detected at the end
of the 12 second delay, the negative (-) connection to
the solenoid is restored and the engine will drop to low
idle RPM.

Return to Section TOCReturn to Section TOCReturn to Section TOCReturn to Section TOC
GENERATING POWER
Flashing
When the engine is running, power from the engine
charging system is stabilized, and then applied to the
rotor brushes through a series of PC board mounted
current limiting resistors and a “flashing” diode.
Building Output
The flashing current produces a weak magnetic field in
the rotor, which is coupled to the now running engine.
This rotating magnetic field begins to generate AC output from all of the stator windings. Output from the
exciter winding is rectified by a diode bridge, filtered by
a capacitor, controlled by circuitry on the PC board,
and fed back into the rotating field winding, making the
magnetic field stronger. This stronger magnetic field
then produces higher voltage from the stator windings,
which feeds back to the rotor, making its magnetic field
even stronger.
This process of strengthening the magnetic field
through feedback from the exciter winding continues to
increase the output of the main generator. If the output
control is set to maximum and the idle switch is in the
Return to Master TOCReturn to Master TOCReturn to Master TOCReturn to Master TOC

OUTBACK® 185
“high” position, all of the windings should be putting out
maximum voltage almost immediately. The rotor field
voltage is now considerably higher than the flashing
voltage that was used to start the generating process.
The “flashing” diode on the control PC board blocks
that higher field voltage from intruding into the 12VDC
battery system.
AC Output
The generator is now producing normal AC power from
all four of the windings. These windings consist of two
64 VAC weld windings, a 120/240 VAC auxiliary power
winding, and an 82 VAC excitation winding.

DC Weld Output
AC output from the two phase-shifted weld windings
pass through a reactor then to a two-phase bridge rectifier. DC output from the rectifier is then stabilized by
a choke and terminates at two weld output terminals.
Weld Output Control
Weld output is controlled by varying the current in the
rotating field winding. This is done through circuitry on
the PC board that detects the position of the output
control potentiometer and then limits the rotor current
accordingly.
NOTE: Because the strength of the rotating field
affects the output of all the windings, auxiliary output
will also drop when the weld output control setting is
decreased.

OUTBACK® 185
Weld Boost:
The Outback® 185 is equipped with a weld boost circuit that improves weld performance. The reactor contains a weld boost winding that produces output relative to the weld current. In high welding load situations,
the exciter winding will tend to drop off in output while
the boost winding’s output tends to increase. The output from this boost winding is routed through a circuit
breaker. It is then rectified and added to the exciter circuit, resulting in a significant improvement in weld performance.

2. Pry outward at the top of the plastic brush cover
while depressing the two locking tabs at the
sides of the cover. See Figure F.5.
3. Remove the brush and brush holder assembly.
4. Use needle-nose pliers to remove the leads
from the brush terminals, and then use the 1/4”
nut driver to remove the two screws holding the
brush holder in place. The brush holder assembly can now be pulled straight out from the end
of the generator toward the front of the
machine.
5. Examine brushes and slip rings. The slip rings,
brush holder, and brushes should be clean and
free from oil or grease. The brushes should be
making good, continuous contact with the slip
rings.
OUTBACK® 185
6. The brushes should be of sufficient length and
have adequate spring tension. Generally, the
brushes should be replaced if either brush has
less than 1/4” remaining before it reaches the
end of its travel. Spring tension should be sufficient to hold the brushes firmly against the slip
rings.
7. The brushes should be removed from the brush
holder and be examined. The terminals should
be clean. The shunt, (braided lead connecting
the carbon brush to the terminal) should be in
good condition and firmly connected to the carbon brush and to the connection terminal.
8. If the slip rings are discolored, display evidence
of excessive sparking, or the brushes have
worn prematurely; these may be signs of a
grounded or shorted roter. Perform The RotorResistance Test.

9. Check for evidence of sticking brushes.
Sticking brushes will normally result in the slip
rings being pitted and discolored from excessive arcing. Another sign of sticking brushes is
instability or loss of both weld and auxiliary output, but the machine may also begin to work
properly for a short time after being jarred or
moved.
10. If there is any evidence that the brushes may
have been sticking in the brush holders, a new
brush holder and brush assembly should be
installed.
Cleaning Slip Rings
1. In the event that the slip rings have become
dirty, discolored or mildly pitted, it will become
necessary to clean them using very fine 500 or
600 grit emery cloth or a 220 or 320 grit commutator stone.
OUTBACK® 185
2. Use low-pressure compressed air to thoroughly
blow the carbon, commutator stone and sandpaper dust from the machine before operating.
3. To install the brush holder assembly, push the
brushes into the brush holder assembly and
place a plastic cable tie through the holes provided. See Figure F.6.
4. Slide the brush holder assembly back into the
generator and secure with the two screws
removed earlier. Reattach the leads and
remove the cable tie. Replace the plastic generator cover.

PROCEDURE
1. Perform Case Cover Removal Procedure.
2. Disconnect anything that may be connected to
the auxiliary receptacles or the weld output terminals.
3. Disconnect and isolate GND-C lead from the
ground stud on the control panel front. See
wiring diagram.
4. Disconnect and isolate lead #5 from the neutral
stud on the control panel bottom. See wiring
diagram.
5. Disconnect the #7 and #9 leads from the PC
board.
6. Using an ohmmeter, check the resistance
between chassis ground and each of the following points; resistance should read very high:
500,000 (500k) ohms minimum.
a) The #5 lead that had been disconnected from
the neutral stud. (This tests for a grounded
auxiliary winding.)
b) The #7 or #9 lead. (This tests for a ground-
ed exciter winding.)
c) W1 or W2 lead. (This tests for a grounded
weld winding.)
d) W3 or W4 lead. (This tests for a grounded
weld winding.)
If any of these readings are less than 500,000
(500k) ohms, check for grounded components or
wiring that remain connected to the stator, such as
circuit breakers, receptacles, output rectifier, reactor, etc. See Wiring Diagram. If necessary, disconnect and isolate the stator leads as close to the
stator winding as possible. If the low resistance to
ground is determined to be in the stator windings,
the stator is defective and should be replaced.
7. If the stator is not grounded, check for short circuit connections between the windings that
should be isolated from each other.
8. Using an ohmmeter; check the resistance
between the following points. Resistance
should red very high, 500,000 (500k) ohms minimum.
a) The #5 lead that had been disconnected
from the neutral stud, and either lead #7 or
lead #9. (This checks for a connection
between the auxiliary power winding and
the excited winding.)
b) The #5 lead that had been disconnected
from the neutral stud, and lead W1 or W2.
(This checks for a connection between the
wire auxiliary power winding and one of
the weld windings.)
c) The #5 lead that has been disconnected from
the neutral stud, and lead W3 or W4. (This
checks for a connection between the auxiliary
power winding and the other weld winding.)
d) Lead #7 and lead W1 or W2. (This checks
for a connection between the exciter winding and one of the weld windings.)
e) Lead #7 and lead W3 or W4. (This checks
for a connection between the exciter winding and the other weld winding.)
If any of the above readings is less than 500,000
(500k) ohms, check for damaged, contaminated, or
shorted wiring, or defective components connected
to the stator windings. If necessary, disconnect
and isolate leads as close to the stator winding as
possible. See Wiring Diagram. If the low resistance is determined to be between the windings
within the stator, the stator is defective and should
be replaced.

ROTOR REMOVAL AND REPLACEMENT PROCEDURE (continued)
FIGURE F.21 – ROTOR LOCATION
PROCEDURE
1. Perform the Stator Removal Procedure.
2. Remove the long through-bolt from the bearing
end of the rotor. (An impact wrench works best
for removing this through-bolt). See Figure
F.21.
3. Remove the rotor from the engine crankshaft
using the Lincoln rotor-pulling tool. See instructions supplied with the tool.
IMPORTANT
Handle and store the rotor very carefully to
avoid damage to the windings.
If necessary, the cast end bracket can now be
removed from the engine.
Replacing the Rotor
1. If the cast end bracket had been removed from
the engine, clean the mating surfaces and reinstall it on the engine at this time. Bolts should
be tightened to a torque of 22 to 24 ft-lbs.
IMPORTANT
It is highly recommended that a new bearing be
installed before the rotor is secured to the
engine crankshaft.
2. Thoroughly clean the engine crankshaft and the
rotor shaft where it mates to the engine crankshaft. Place the rotor on the crankshaft.
3. When installing rotor thru-bolt, apply threadlocking compound, (Locktite 2760 or equivalent) torque the rotor thru-bolt to 22 to 24 ft-lbs.
4. After the rotor is secured to the engine crankshaft, check the run-out at the bearing outer
race. Run out should not exceed .015” F.I.M.
5. See the stator removal and installation procedures for further assembly instructions.
