BE SURE THAT ALL INSTALLATION, OPERATION, MAINTENANCE AND REPAIR PROCEDURES ARE
PERFORMED ONLY BY QUALIFIED INDIVIDUALS.

The engine exhaust from this product contains
chemicals known to the State of California to cause
cancer, birth defects, or other reproductive harm.

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.

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.

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.

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

though

they have

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.

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.

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.

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

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.

HIGH TEMPERATURE OPERATION

At temperatures above 40°C, output de-rating is nec­essary. For maximum output ratings, de-rate the
welder output 2Volts for every 10°C above 40°C.

TOWING

The recommended trailer for use with this equipment
for road, in-plant and yard towing by a vehicle
Lincoln’s K957-1. 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. Some of
the factors to be considered are as follows:

1. Design capacity of trailer 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 trailer to

insure stability side to side and front to back when
being moved and when standing by itself while
being operated or serviced.

4. Typical conditions of use, i.e., travel speed; rough­ness of surface on which the trailer will be operat­ed; environmental conditions.

SPARK ARRESTER

Some federal, state or local laws may require that
gasoline or diesel 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, a suitable spark arrester, such as
the S24647 must be installed and properly main­tained.

FUEL

USE GASOLINE FUEL ONLY

WARNING

Fill the fuel tank with clean, fresh fuel. The capaci­ty of the fuel tank is 12 gallons (45.4 liters). When
the fuel gauge reads empty the tank contains
approximately 2 gallons (45.4 liters).of reserve
fuel.

NOTE: The fuel tank is mounted below the engine

so a fuel shutoff valve is not required.

-----------------------------------------------------------------------

ENGINE COOLING SYSTEM

Air to cool the engine is drawn in lower set of louvers
on the case back. It is important that the intake air is
not restricted. Allow a minimum clearance of 2 feet
(0.6m) from the case back to a vertical surface.

HIGH FREQUENCY GENERATORS FOR
TIG APPLICATIONS

The K930-2 TIG Module is suitable for use with the
Ranger 250. The Ranger 250 and any high frequency
generating equipment must be properly grounded.
See the K930-2 Operating Manual for completed
instructions on installation, operation, and mainte­nance.

REMOTE CONTROL

The Ranger 250 is equipped with a 6 pin and a 14 pin
Amphenol connector. The 6 pin connector is for con­necting the K857 or K857-1 Remote Control (optional)
or for TIG welding, the K870 foot Amptrol or the K812
hand Amptrol.

A-5

When in the CC-STICK, PIPE, and CV-WIRE modes
and when a remote control is connected to the
Amphenol, the auto-sensing circuit in the Ranger 250
automatically switches the OUTPUT control from con­trol at the welder to remote control .

INSTALLATION

A-5

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.

The 14 pin connector is used to directly connect a
wire feeder or TIG Module (K930-2) control cable. In
the CV-WIRE mode, the Ranger 250 auto-sensing cir­cuit automatically makes the Ranger 250 Output
Control inactive and the wire feeder voltage control
active when the control cable is connected to the 14
pin connector.

NOTE: When a wire feeder with a built in welding volt­age control is connected to the 14 pin connector, do
not connect anything to the 6 pin connector.

ELECTRICAL CONNECTIONS

MACHINE GROUNDING

Because this portable engine driven welder
creates its own power, it is not necessary to connect
its frame to an earth ground, unless the machine is
connected to premises wiring (home, shop, etc.)

To prevent dangerous electric shock, other equipment
to which this engine driven welder supplies power
must:

1) Be grounded to the frame of the welder using a

grounded type plug.

WELDING TERMINALS

The Ranger 250 is equipped with a toggle switch for
selecting "hot" welding terminal when in the "WELD
TERMINALS ON" position or "cold" welding terminal
when in the "REMOTELY CONTROLLED" position.

WELDING OUTPUT CABLES

With the engine off connect the electrode and work
cables to the output studs. The welding process dic­tates the polarity of the electrode cable. These con­nections should be checked periodically and tightened
with a 3/4" wrench.

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.

------------------------------------------------------------------------

When this welder is mounted on a truck or trailer, its
frame must be securely connected to the metal frame
of the vehicle. When this engine driven welder is con­nected to premises wiring such as that in a home or
shop, its 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.

• Do not cross the welding cables at the output
terminal connection. Keep the cables isolated
and separate from one another.

------------------------------------------------------------------------

AUXILIARY POWER RECEPTACLES

The auxiliary power of the RANGER 250 consists of
two 20 Amp-120 VAC (5-20R) duplex receptacles and
one 50 Amp 120/240 VAC (14-50R) receptacle. The
240 VAC receptacle can be split for single phase 120
VAC operation.

The auxiliary power capacity is 9,000 Watts Peak,
8500 Watts Continuous of 60 Hz, single phase power.
The auxiliary power capacity rating in watts is equiva­lent to volt-amperes at unity power factor. The max
permissible current of the 240 VAC output is 35 Amps.
The 240 VAC output can be split to provide two sepa­rate 120 VAC outputs with a max permissible current
of 35 Amps per output to two separate 120 VAC
branch circuits (these circuits cannot be paralleled).
Output voltage is within ± 10% at all loads up to rated
capacity.

1. Install the double-pole, double-throw switch
between the power company meter and the premis­es disconnect. Switch rating must be the same or
greater than the customer’s premises disconnect
and service over current protection.

2. Take necessary steps to assure load is limited to
the capacity of the RANGER 250 by installing a 40
amp, 240 VAC double pole circuit breaker.
Maximum rated load for each leg of the 240 VAC
auxiliary is 35 amperes. Loading above the rated
output will reduce output voltage below the allow­able - 10% of rated voltage which may damage
appliances or other motor-driven equipment and
may result in overheating of the RANGER 250
engine and/or alternator windings.

3. Install a 50 amp, 120/240 VAC plug (NEMA Type
14-50) to the double-pole circuit breaker using No.
6, 4 conductor cable of the desired length. (The 50
amp, 120/240 VAC plug is available in the optional
K802R plug kit or as part number T12153-9.)

4. Plug this cable into the 50 Amp, 120/240 Volt
receptacle on the RANGER 250 case front.

The 120 V auxiliary power receptacles should only be
used with three wire grounded type plugs or approved
double insulated tools with two wire plugs. The current
rating of any plug used with the system must be at
least equal to the current capacity of the associated
receptacle.

NOTE: The 240 V receptacle has two 120 V circuits,
but are of opposite polarities and cannot be paralleled.

STANDBY POWER CONNECTIONS

The RANGER 250 is suitable for temporary, standby
or emergency power using the engine manufacturer’s
recommended maintenance schedule.

The RANGER 250 can be permanently installed as a
standby power unit for 240 VAC, 3 wire, single phase,
35 amp service. Connections must be made by a
licensed electrician who can determine how the
120/240 VAC power can be adapted to the particular
installation and comply with all applicable electrical
codes.

WELDING CONTROLS:

1. OUTPUT CONTROL: The CONTROL dial

provides continuous control of the welding current or
welding voltage depending on the selected welding
mode. This control is not active in the CC-STICK,
PIPE, and CV-WIRE modes when a remote control or
wire feeder with remote control is connected to either
the 6 pin or 14 pin Amphenol.

2. WELD MODE SELECTOR SWITCH:

(Provides four selectable welding modes)

CV-WIRE
PIPE
CC-STICK
TOUCH START TIG

7

6

5

CC-STICK/PIPE modes: In these modes, the ARC
CONTROL knob sets the short circuit current during
stick welding (arc-force). Increasing the number from ­10 to +10 increases the short circuit current and pre­vents sticking of the electrode to the plate while weld­ing. This can also increase spatter. It is recommended
that the ARC CONTROL be set to the minimum num­ber without electrode sticking. Start with a setting at 0.

CV-WIRE mode: In this mode, turning the ARC CON­TROL clockwise from –10 (soft) to +10 (crisp) changes
the arc from soft and washed-in to crisp and narrow. It
acts as an inductance control. The proper setting
depends on the procedure and operator preference.
Start with a setting at 0.

3. ARC CONTROL:

The ARC CONTROL WIRE/STICK dial is active in
the WIRE, STICK and PIPE modes, and has different
functions in these modes. This control is not active in
the TIG mode. DC PIPE mode for machines below
code 10900.

4. WELD OUTPUT TERMINALS WITH
FLANGE NUT:

Provides a connection point for the electrode and work
cables.

B-3

OPERATION

5. GROUND STUD: (graphic)

Provides a connection point for connecting the
machine case to earth ground for the safest grounding
procedure.

6. 14-PIN AMPHENOL:

For attaching wire feeder control cables to the Ranger

250. Includes contactor closure circuit, auto-sensing
remote control circuit, and 120V and 42V power. The
remote control circuit operates the same as the 6 Pin
Amphenol.

7. 6-PIN AMPHENOL:

For attaching optional remote control equipment.
When in the CC-STICK, PIPE, and CV-WIRE modes
and when a remote control is connected to the
Amphenol, the auto-sensing circuit in the Ranger 250
automatically switches the OUTPUT control from con­trol at the welder to remote control .

When using the TOUCH START TIG mode with a TIG
Module connected to the Ranger 250, the OUTPUT
control on the front of the Ranger 250 is used to set
the maximum current range of the CURRENT CON­TROL on the TIG Module.

8. WELD TERMINALS CONTROL SWITCH:

In the WELD TERMINALS ON position, the output is
electrically hot all the time. In the REMOTELY CON­TROLLED position, the output is controlled by a wire
feeder or amptrol device, and is electrically off until a

remote switch is depressed.

9. WIRE FEEDER VOLTMETER SWITCH:

Matches the polarity of the wire feeder voltmeter to
the polarity of the electrode.

ENGINE CONTROLS:

10. RUN/STOP SWITCH - RUN position ener-

gizes the engine prior to starting. STOP position stops
the engine. The oil pressure interlock switch prevents
battery drain if the switch is left in the RUN position
and the engine is not operating.

B-3

2) In the AUTO position, the idler operates as follows:

• When switched from HIGH to AUTO or after start-

ing the engine, the engine will operate at full
speed for approximately 12 seconds and then go
to low idle speed.

• When the electrode touches the work or power is

drawn for lights or tools (approximately 100 Watts
minimum), the engine accelerates and operates
at full speed.

• When welding ceases or the AC power load is

turned off, a fixed time delay of approximately 12
seconds starts. If the welding or AC power load is
not restarted before the end of the time delay, the
idler reduces the engine speed to low idle speed.

• The engine will automatically return to high idle

speed when there is welding load or AC power
load reapplied.

14. ENGINE ALTERNATOR TROUBLE

LIGHT-The engine alternator light is off when battery

charging system is functioning normally. If light turns
on, the alternator or the voltage regulator may not be
operating correctly. The light may also come on due
to the battery not holding a charge. It is normal for the
light to come on during shut down of the engine. The
light will remain lit with the meters for a short period of
time after the engine has shut down.

15. ENGINE HOUR METER – Displays the total

time that the engine has been running. This meter is
useful for scheduling prescribed maintenance.

STARTING AND STOPPING
THE ENGINE

minutes before applying a load and/or switching to
high idle. Allow a longer warm up time in cold
weather.

B-4

OPERATION

B-4

CAUTION

Operating the starter motor for more than 5 sec­onds can damage the motor. If the engine fails to
start, release the switch and wait 10 seconds
before operation the starter again. Do NOT push
the START button while the engine is running
because this can damage the ring gear and/or the
starter motor.

NOTE: When starting a Ranger 250 for the first time,
or after an extended period of time of not operating, it
will take longer than normal because the fuel pump
has to fill the fuel line and carburetor.

STOPPING

Remove all welding and auxiliary power loads and
allow the engine to run at low idle speed for a few
minutes to cool the engine.

Stop the engine by placing the RUN-STOP in the
STOP position.

NOTE: A fuel shut off valve is not required on the
Ranger 250 because the fuel tank is mounted below
the engine.

WELDER OPERATION

DC Stick Welding

The Ranger 250 can be used with a broad range of
DC stick electrodes.
The MODE switch provides two stick welding settings
as follows:

Constant Current (CC-STICK) Welding

The CC-STICK position of the MODE switch is
designed for horizontal and vertical-up welding with all
types of electrodes, especially low hydrogen. The out­put CONTROL dial adjusts the full output range for
stick welding.

The ARC CONTROL knob sets the short circuit cur­rent during stick welding (arc-force). Increasing the
number from -10 to +10 increases the short circuit cur­rent and prevents sticking of the electrode to the plate
while welding. This can also increase spatter. It is rec­ommended that the ARC CONTROL be set to the
minimum number without electrode sticking. Start with
the dial set at 0.

PIPE Welding

This slope controlled setting is intended for "out-of­position" and "down hill" pipe welding where the oper­ator would like to control the current level by changing
the arc length. The output CONTROL dial adjusts the
full output range for pipe welding. The ARC CON­TROL knob sets the short circuit current during stick
welding (arc-force). Increasing the number from -10 to
+10 increases the short circuit current and prevents
sticking of the electrode to the plate while welding.
This can also increase spatter. It is recommended that
the ARC CONTROL be set to the minimum number
without electrode sticking. Start with the dial set at 0.

ARC GOUGING

The Ranger 250 can be used for limited arc gouging.
For optimal performance, set the MODE switch to CC­STICK and the ARC CONTROL to +10.

Set the CONTROL knob to adjust output current to the
desired level for the gouging electrode being used
according to the ratings in the following table.

3/16" (4.0mm) 150-200 Amps

AUXILIARY POWER:

Start the engine and set the IDLER control switch to
the desired operating mode. Full power is available
regardless of the welding control settings providing no
welding current is being drawn.

The auxiliary power of the RANGER 250 consists of
two 20 Amp-120 VAC (5-20R) duplex receptacles and
one 50 Amp 120/240 VAC (14-50R) receptacle. The
240 VAC receptacle can be split for single phase 120
VAC operation.

The auxiliary power capacity is 9,000 Watts Peak,
8500 Watts Continuous of 60 Hz, single phase power.
The auxiliary power capacity rating in watts is equiva­lent to volt-amperes at unity power factor. The max
permissible current of the 240 VAC output is 35 Amps.

The 240 VAC output can be split to provide two sepa­rate 120 VAC outputs with a max permissible current
of 35 Amps per output to two separate 120 VAC
branch circuits (these circuits cannot be paralleled).
Output voltage is within ± 10% at all loads up to rated
capacity.

The 120 V auxiliary power receptacles should only be
used with three wire grounded type plugs or approved
double insulated tools with two wire plugs. The current
rating of any plug used with the system must be at
least equal to the current capacity of the associated
receptacle.

NOTE: The 240 V receptacle has two circuits, each of
which measure 120 V to neutral but are of opposite
polarities and cannot be paralleled.

Simultaneous Welding and Auxiliary Power Loads

The above auxiliary power ratings are with no welding
load. Simultaneous welding and power loads are
specified in the following table. The permissible cur­rents shown assume that current is being drawn from
either the 120 VAC or 240 VAC supply (not both at the
same time).

BATTERY MAINTENANCE

To access the battery, Remove the 2 screws from the
rear battery tray using a screwdriver or a 3/8" socket.
Slide the battery tray out only far enough to access
the battery terminals.

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.

• 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 neg­ative battery lead at 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.

CLEANING THE BATTERY

Keep the battery clean by wiping it with a damp cloth
when dirty. If the terminals appear corroded, discon­nect the battery cables and wash the terminals with an
ammonia solution or a solution of 1/4 pound (0.12 kg)
of baking soda and 1 quart (0.9461liter) of water. Be
sure the battery vent plugs (if equipped) are tight so
that none of the solution enters the cells.
After cleaning, flush the outside of the battery, the bat­tery compartment, and surrounding areas with clear
water. Coat the battery terminals lightly with petroleum
jelly or a non-conductive grease to retard corrosion.
Keep the battery clean and dry. Moisture accumula­tion on the battery can lead to more rapid discharge
and early battery failure.

CHECKING THE ELECTROLYTE LEVEL

If battery cells are low, fill them to the neck of the filler
hole with distilled water and recharge. If one cell is
low, check for leaks.

CHARGING THE BATTERY

When you charge, jump, replace, or otherwise con­nect battery cables to the battery, be sure the polarity
is correct. Improper polarity can damage the charging
circuit. The RANGER 250 positive (+) battery terminal
has a red terminal cover.
If you need to charge the battery with an external
charger, disconnect the negative cable first, then the
positive cable before you attach the charger leads.
After the battery is charged, reconnect the positive
battery cable first and the negative cable last. Failure
to do so can result in damage to the internal charger
components.
Follow the instructions of the battery charger manu­facturer for proper charger settings and charging time.
