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.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.
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.
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.
___________________________________________________
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.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.

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
coming from degreasing, cleaning or spraying operations.
The heat and rays of the arc can react with solvent vapors
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.

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.
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
been “cleaned”. For information, purchase “Recommended
Safe Practices for the
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.
Sparks and spatter are thrown from the welding arc. Wear oil
6.f.
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.
Remember that welding sparks and hot

STORING
1. Store the machine in a cool, dry place when it is not
in use. Protect it from dust and dirt. Keep it where
it can’t be accidentally damaged from construction
activities, moving vehicles, and other hazards.
2. Drain the engine oil and refill with fresh 10W30 oil.
Run the engine for about five minutes to circulate
oil to all the parts. See the MAINTENANCE section
of this manual for details on changing oil.
3. If you are storing the machine for more than 30
days, drain the coolant from the radiator. Open the
cock at the bottom of the radiator and remove the
pressure cap so that the coolant drains completely.
Attach a note that says “NO WATER” on the radiator.
4. Remove the battery, recharge it, and adjust the
electrolyte level. Store the battery in a dry, dark
place.
Only qualified personnel should install,
use, or service this equipment.
LOCATION AND VENTILATION
Whenever you use the RANGER 300, be sure that
clean cooling air can flow through the machine’s
diesel engine and the machine case. Avoid dusty,
dirty areas. Also, keep the machine away from heat
sources. Do not place the engine end of the machine
anywhere near hot engine exhaust from another
machine or closer than two feet from a wall. And of
course, make sure that engine exhaust is ventilated to
an open, outside area.
The RANGER 300 may be used outdoors. Do not set
the machine in puddles or otherwise submerge it in
water. Such practices pose safety hazards and cause
improper operation and corrosion of parts.
Always operate the RANGER 300 with the case roof
on and all machine components completely assembled. This will protect you from the dangers of moving
parts, hot metal surfaces, and live electrical devices.
5. If the engine is not used for a long period of time,
every two to three months fill the radiator and run
the engine for about five minutes to keep it free
from rust.
STACKING
RANGER 300 machines CANNOT be stacked.
TILTING
Place the machine on a secure, level surface whenever you use it or store it. Any surfaces you place it on
other than the ground must be firm, non-skid, and
structurally sound.
The diesel engine is designed to run in a level position
for best performance. It can operate at an angle, but
this should never be more than 20 degrees in any
direction. If you do operate it at a slight angle, be sure
to check the oil regularly and keep the oil level at the
FULL mark as it would be in its normal level condition.
Also, fuel capacity will be a little less at an angle.

------------------------------------------------------------------------
WARNING
• Keep hands way from the engine muffler or HOT
engine parts.
• Stop the engine when fueling.
• Do not smoke when fueling.
• Do not overfill the fuel tank.
The recommended undercarriage for use with this
equipment for in-plant and yard towing by a vehicle is
Lincoln’s K953-1. If the user adapts a non-Lincoln
undercarriage, he must assume responsibility that the
method of attachment and usage does not result in a
safety hazard nor damage the welding equipment.
Some of the factors to be considered are as follows:
1. Design capacity of undercarriage vs. weight of
Lincoln equipment and likely additional attachments.
2. Proper support of, and attachment to, the base of
the welding equipment so there will be no undue
stress to the framework.
3. Proper placement of the equipment on the undercarriage to insure stability side to side and front to
back when being moved and when standing by
itself while being operated or serviced.

MACHINE GROUNDING
Because the RANGER 300 creates its own power
from its diesel-engine driven generator, and if the
machine is not connected to premises wiring (home,
shop, etc.), you do not need to connect the machine
frame to an earth ground. However, for best protection against electrical shock, connect a heavy gauge
wire (#8 AWG or larger) from the ground stud located
on the bottom of the output panel (See Figure B.1) to
a suitable earth ground such as a metal pipe driven
into the ground.
WARNING
Do not ground the machine to a pipe that carries
explosive or combustible material.

CABLE INSTALLATION
Install the welding cables to your RANGER 300 as follows. See Figure B.1 for location of parts.
1. The diesel engine must be OFF to install welding
cables.
When the Ranger 300 is mounted on a truck or a trailer, the machine generator ground stud MUST be
securely connected to the metal frame of the vehicle.
See Figure B.1. The ground stud is marked with the
ground symbol.
If the RANGER 300 is connected to premises wiring
such as a home or shop, it must be properly connected to the system earth ground.
WELDING CABLE CONNECTIONS
CABLE SIZE AND LENGTH
Be sure to use welding cables that are large enough.
The correct size and length becomes especially
important when you are welding at a distance from the
welder.
Table A.1 lists recommended cable sizes and lengths
for 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.
2. Remove the flanged nuts from the output terminals.
3. Connect the electrode holder and work cables to
the weld output terminals. The terminals are identified on the case front.
4. Tighten the flanged nuts securely.
5. Be certain that the metal piece you are welding (the
“work”) is properly connected to the work clamp and
cable.
6. Check and tighten the connections periodically.
CAUTION
• Loose connections will cause the output terminals to
overheat. The terminals may eventually melt.
• Do not cross the welding cables at the output terminal connection. Keep the cables isolated and separate from one another.

AUXILIARY POWER RECEPTACLES,
PLUGS, AND HAND-HELD EQUIPMENT
The control panel of the RANGER 300 features three
auxiliary power receptacles: See Figure B.1.
• Two 15 amp, 120 volt duplex (double outlet) receptacles.
• One 50 amp 120/240 volt simplex (single outlet)
receptacle.
Through these receptacles the machine can supply up
to 12,000 rated continuous watts of single-phase, 60
Hz AC power.
For further protection against electric shock, any electrical equipment connected to the generator receptacles must use a three-blade, grounded type plug or an
Underwriter’s Laboratories (UL) approved double
insulation system with a two-blade plug. Lincoln
offers an accessory plug kit that has the right type of
plugs. See the ACCESSORIES section of this manual
for more information.
If you need ground fault protection for hand-held
equipment refer to the K896-1 GFCI Receptacle kit in
the ACCESSORIES section of this manual for more

CIRCUIT BREAKERS
PREMISES WIRING
The RANGER 300 is suitable for temporary, standby,
or emergency power using the engine manufacturer’s
recommended maintenance schedule. With its threewire grounded neutral generator, it can be permanently installed as a standby power unit for 240 volt, three
wire, single phase 50 ampere service.
WARNING
Only a licensed, certified, trained electrician should
install the machine to a premises or residential electrical system. Be certain that:
• The installation complies with the National Electrical
Code and all other applicable electrical codes.
• The premises is isolated and no feedbacking into
the utility system can occur. Certain state and local
laws require the premises to be isolated before the
generator is linked to the premises. Check your
state and local requirements.
• A double pole, double throw transfer switch in conjunction with the properly rated double throw circuit
breaker is connected between the generator power
and the utility meter.
------------------------------------------------------------------------
The following information and the connection diagram,
Figure A.1, can be used as a guide by the electrician
for most applications to premises wiring.
The RANGER 300 machines are equipped with 50
amp circuit breakers on the 120/240 V receptacle and
15 amp circuit breakers on the 120 receptacles for
overload protection. Under high heat a breaker may
tend to trip at lower loads than it would normally.
CAUTION
Never bypass the circuit breakers. Without overload
protection, the RANGER 300 D/DLX could overheat
and/or cause damage to the equipment being used.
------------------------------------------------------------------------
1. Install a double pole, double throw switch between
the power company meter and the premises disconnect. The switch rating must be the same as or
greater than the premises disconnect and service
overcurrent protection.
2. Take the necessary steps to assure that the load is
limited to the capacity of the RANGER 300 by
installing a 50 amp 240 volt double pole circuit
breaker. Maximum rated load for the 240 volt auxiliary is 50 amperes. Loading above 50 amperes will
reduce output voltage below the allowable -10% of
rated voltage. This may damage appliances or
other motor-driven equipment.
3. Install a 50 amp 120/240 volt plug (NEMA type 14-
50) to a double pole circuit breaker using No. 8 or
larger, 4 conductor cable of the desired length.
(The 50 amp 120/240 volt plug is available in the
optional power plug kit.
4. Plug this cable in to the 50 amp 120/240 volt receptacle on the RANGER 300 case front.

GENERAL DESCRIPTION
The RANGER 300 is a diesel-engine driven, multiprocess AC and DC arc welder and AC power generator for commercial and residential applications. As a
generator it can supply up to 12,000 continuous watts
of 120/240 volt, 60 Hz, single-phase AC power to
operate AC power tools, battery chargers, and lighting; it can also be used to provide standby power. As
a welder it provides 300 amps of AC current for welding with AC stick electrodes or 300 amps of DC current for DC stick welding. The RANGER 300 can also
perform AC/DC TIG welding and DC semiautomatic
wire feed welding.
The engine used on the Ranger 300 machines is the
Kubota "Super Five" water-cooled, 3 cylinder DH905
engine. The DH905 has an offset piston design with
built in steel strut and a more rigid crank-case. The
Kubota "Three Vortex Combustion System" gives
higher power output, lower fuel consumption, lower
noise, and cleaner exhaust. The "Super Glow
System" gives rapid pre-heating for easy starting in
cold weather. The large oil sump adds to the long life
of this engine. The high capacity 30 amp alternator
gives fast charging of the 495 CCA battery. The
engine is extremely smooth and has very low vibration, even at low idle speed.
The Ranger 300 machines are housed in a heavy
gauge steel case that is protected by a durable powder paint finish. The case is completely insonorized for
remarkably quiet operation. An easy to open hinged
door allows access to the engine for single side service. The welder alternator has all copper windings
and a high temperature insulation system that
includes three coats of electrical grade varnish.
