BE SURE THAT ALL INSTALLATION, OPERATION, MAINTENANCE AND REPAIR PROCEDURES ARE
PERFORMED ONLY BY QUALIFIED INDIVIDUALS.
FOR ENGINE
powered equipment.
1.h. To avoid scalding, do not remove the
radiator pressure cap when the engine is
hot.
1.a. Turn the engine off before troubleshooting and maintenance
work unless the maintenance work requires it to be running.
____________________________________________________
1.b. Operate engines in open, well-ventilated
areas or vent the engine exhaust fumes
outdoors.
____________________________________________________
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.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.
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.
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.
___________________________________________________
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.
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 below Threshold Limit Values (TLV)
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. Do not weld in locations near chlorinated hydrocarbon vapors
coming from degreasing, cleaning or spraying operations.
The heat and rays of the arc can react with solvent vapors to
form phosgene, a highly toxic gas, and other irritating
products.
5.c. Shielding gases used for arc welding can displace air and
cause injury or death. Always use enough ventilation,
especially in confined areas, to insure breathing air is safe.
5.d. Read and understand the manufacturer’s instructions for this
equipment and the consumables to be used, including the
material safety data sheet (MSDS) and follow your
employer’s safety practices. MSDS forms are available from
your welding distributor or from the manufacturer.
5.e. Also see item 1.b.

SAFETY
WELDING SPARKS can
cause fire or explosion.
6.a. Remove fire hazards from the welding area.
If this is not possible, cover them to prevent
the welding sparks from starting a fire.
Remember that welding sparks and hot
materials from welding can easily go through small cracks
and openings to adjacent 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 though they have
been “cleaned”. For information, purchase “Recommended
Safe Practices for the Preparation for Welding and Cutting of
Containers and Piping That Have Held Hazardous
Substances”, AWS F4.1 from the American Welding Society
(see address above).
6.e. Vent hollow castings or containers before heating, cutting or
welding. They may explode.
6.f. Sparks and spatter are thrown from the welding arc. Wear oil
free protective garments such as leather gloves, heavy shirt,
cuffless trousers, high shoes and a cap over your hair. Wear
ear plugs when welding out of position or in confined places.
Always wear safety glasses with side shields when in a
welding area.
6.g. Connect the work cable to the work as close to the welding
area as practical. Work cables connected to the building
framework or other locations away from the welding area
increase the possibility of the welding current passing
through lifting chains, crane cables or other alternate circuits. This can create fire hazards or overheat lifting chains
or cables until they fail.
6.h. Also see item 1.c.
CYLINDER may explode
if damaged.
7.a. Use only compressed gas cylinders
containing the correct shielding gas for the
process used and properly operating
regulators designed for the gas and
pressure used. All hoses, fittings, etc. should be suitable for
the application and maintained in good condition.
7.b. Always keep cylinders in an upright position securely
chained to an undercarriage or fixed support.
7.c. Cylinders should be located:
• Away from areas where they may be struck or subjected to
physical damage.
• A safe distance from arc welding or cutting operations and
any other source of heat, sparks, or flame.
7.d. Never allow the electrode, electrode holder or any other
electrically “hot” parts to touch a cylinder.
7.e. Keep your head and face away from the cylinder valve outlet
when opening the cylinder valve.
7.f. Valve protection caps should always be in place and hand
tight except when the cylinder is in use or connected for
use.
7.g. Read and follow the instructions on compressed gas
cylinders, associated equipment, and CGA publication P-l,
“Precautions for Safe Handling of Compressed Gases in
Cylinders,” available from the Compressed Gas Association
1235 Jefferson Davis Highway, Arlington, VA 22202.
FOR ELECTRICALLY
powered equipment.
8.a. Turn off input power using the disconnect
switch at the fuse box before working on
the equipment.
8.b. Install equipment in accordance with the U.S. National
Electrical Code, all local codes and the manufacturer’s
recommendations.
8.c. Ground the equipment in accordance with the U.S. National
Electrical Code and the manufacturer’s recommendations.

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:
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.
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
TRANSFORMATEUR ET À
REDRESSEUR
1. Relier à la terre le chassis du poste conformement au code
de l’électricité et aux recommendations du fabricant. Le dispositif de montage ou la piece à souder doit être branché à
une bonne mise à la terre.
2. Autant que possible, I’installation et l’entretien du poste
seront effectués par un électricien qualifié.
3. Avant de faires des travaux à l’interieur de poste, la
debrancher à l’interrupteur à la boite de fusibles.
4. Garder tous les couvercles et dispositifs de sûreté à leur
place.

INSTALLATION INSTRUCTIONS
Safety Precautions
WARNING
Do not attempt to use this equipment until you
have thoroughly read the engine manufacturer’s
manual supplied with your welder. It includes
important safety precautions, detailed engine
starting, operating and maintenance instructions,
and parts lists.
-----------------------------------------------------------------------ELECTRIC SHOCK can kill.
• Do not touch electrically live parts or
electrode with skin or wet clothing.
• Insulate yourself from work and
ground
• Always wear dry insulating gloves.
-----------------------------------------------------------------------ENGINE EXHAUST can kill.
• Use in open, well ventilated areas or
vent exhaust outside.
• The combustion of LPG fuel does produce carbon monoxide. Although the level
of CO emission is lower than gasoline combustion, the
exhaust from the Ranger 8 LPG can kill.
-----------------------------------------------------------------------MOVING PARTS can injure.
• Do not operate with doors open or
guards off.
• Stop engine before servicing.
• Keep away from moving parts.
------------------------------------------------------------------------
Where this engine driven welder is connected to
premises wiring such as that in your home or shop, it’s
frame must be connected to the system earth ground.
See further connection instructions in the section entitled “Standby Power Connections”, as well as the article on grounding in the latest U.S. National Electrical
Code and the local code.
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.
Spark Arrester
Some federal, state, or local laws may require that
gasoline engines be equipped with exhaust spark
arresters when they are operated in certain locations
where unarrested sparks may present a fire hazard.
The standard muffler included with this welder does
not qualify as a spark arrester. When required by
local regulations, the K894-1 spark arrester must be
installed and properly maintained.
See additional warning information at
front of this operator’s manual.
----------------------------------------------------------Machine Grounding
Because this portable engine driven welder or generator creates it’s own power, it is not necessary to connect it’s frame to an earth ground, unless the
machine is connected to premises wiring (your home,
shop, etc.).
CAUTION
An incorrect arrester may lead to damage to the
engine or adversely affect performance.
Trailers
To prevent dangerous electric shock, other equipment to which this engine driven welder supplies
power must:
If the user adapts a non-Lincoln trailer, he must
assume responsibility that the method of attachment
and usage does not result in a safety hazard nor damage the welding equipment.
a. be grounded to the frame of the welder using a
grounded type plug, or
Some of the factors to be considered are as follows:
b. be double insulated.
1. Design capacity of trailer vs. weight of Lincoln
equipment and likely additional attachments.
When this welder is mounted on a truck or trailer, it’s
frame must be securely connected to the metal frame
of the vehicle.
2. Proper support of, and attachment to, the base of
the welding equipment so there will be no undue
stress to the framework.

below the allowable -10% of rated voltage which
may damage appliances or other motor driven
equipment.
Switch rating must be the same or greater than
the customer’s premises disconnect and service
overcurrent protection.
3. Install a 50 amp 115/230V plug (NEMA type 14-50)
to the Double Pole Circuit Breaker using No. 8,
4 conductor cable of the desired length. (The
50 amp 115/230V plug is available in the

MAINTENANCE
Safety Precautions
WARNING
• Have qualified personnel do maintenance and
troubleshooting work.
•
Turn the engine off before working inside the
machine.
•
Remove guards only when necessary to
perform maintenance, and replace them when
the maintenance requiring their removal is
complete.
•
If guards are missing from a machine, obtain
replacements from a Lincoln Distributor. (See
Machine Parts List.)
More frequent oil changes are required with dusty,
high temperature and other severe operating conditions. Refer to the maintenance section of the Engine
Owner's Manual for more information.
NOTE: Engine life will be reduced if the oil and oil
filter are not changed according to the manufacturer’s
recommendation.
3.
Air Cleaner - With normal operating conditions,
the maintenance schedule for cleaning and re-oiling the foam pre-filter is every 25 hours and
replacement of the air cleaner filter every 100
hours. More frequent servicing is required with
dusty operating conditions. Refer to the maintenance section of the Engine Owner’s Manual for
more information.
4.
Refer to the maintenance section of the Engine
Owner’s Manual for the maintenance schedule,
spark plug servicing and cooling system servicing.
5.
Blow out the machine with low pressure air
periodically. In particularly dirty locations, this
may be required once a week.
Read the Safety Precautions in the front of this manual and the engine instruction manual before working
on this machine.
Keep all equipment safety guards, covers, and
devices in position and in good repair. keep hands,
hair, clothing, and tools away from gears, fans, and all
other moving parts when starting, operating, or repairing the equipment.
Routine Maintenance
1. At the end of each day’s use, make certain that the
valve on the LPG fuel supply cylinder is closed.
Check the crankcase oil level, add oil if needed.
CAUTION
6. Output Ranger Selector and Polarity Switches:
Switch contacts should not be greased. To keep
contacts clean, rotate the switch through its entire
range frequently. Good practice is to turn the handle from maximum to minimum setting twice each
morning before starting to weld.
Engine Adjustments
Make certain that the oil filler cap is securely tightened after checking or adding oil. If the cap is not
tight, oil consumption can increase significantly
which may be evidenced by white smoke coming
from the exhaust.

Slip Rings
1.
When replacing, jumping, or otherwise connecting
the battery to the battery cables, the proper
polarity must be observed. Failure to observe
the proper polarity could result in damage to the
charging circuit. The positive (+) battery cable
has a red terminal cover.
2.
If the battery requires charging from an external
charger, disconnect the negative battery cable
first and then the positive battery cable before
attaching the charger leads. Failure to do so
can result in damage to the internal charger
components. When reconnecting the cables,
connect the positive cable first and the negative
cable last.
A slight amount of darkening and wear of the slip rings
and brushes is normal. Brushes should be inspected
when a general overhaul is necessary. If brushes are
to be replaced, clean slip rings with a fine emery
paper.
CAUTION
Do not attempt to polish slip rings while engine is
running.
Battery
WARNING
GASES FROM BATTERY can explode.
• Keep sparks, flame and cigarettes away from battery.
To prevent EXPLOSION when:
• INSTALLING A NEW BATTERY - disconnect negative
cable from old battery first and connect to new battery
last.
Hardware
Both English and Metric fasteners are used in this
welder.
• CONNECTING A BATTERY CHARGER - Remove battery from welder by disconnecting negative cable first,
then positive cable and battery clamp. When reinstalling, connect negative cable last. Keep well ventilated.
• USING A BOOSTER - connect positive lead to battery
first then connect negative lead to engine foot.
BATTERY ACID CAN BURN EYES AND SKIN.
• Wear gloves and eye protection and be careful when
working near battery. Follow instructions printed on
battery.

to visualize mechanically drawn objects as they will appear
in their assembled form.
