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 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.

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

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.

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.
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
zones où l’on pique le laitier.
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 ALTITUDE OPERATION
At higher altitudes, Welder output de-rating may be necessary. For
maximum rating, de-rate the welder output 3.5% for every 1000 ft.
(305m). Contact an authorized engine service shop for modifications to operate above 5,000 ft. (1525m).
Only qualified personnel should install,
use, or service this equipment.
LOCATION AND VENTILATION
The welder should be located to provide an unrestricted flow of clean, cool air to the cooling air inlets and to
avoid restricting the cooling air outlets. Also, locate the
welder so that the engine exhaust fumes are properly
vented to an outside area.
STACKING
RANGER 305G machines cannot be stacked.
ANGLE OF OPERATION
Engines are designed to run in the level condition
which is where the optimum performance is achieved.
The maximum angle of continuous operation is 15
degrees in any direction. If the engine is to be operated at an angle, provisions must be made for checking
and maintaining the oil level at the normal (FULL) oil
capacity in the crankcase.
When operating the welder at an angle, the effective
fuel capacity will be slightly less than the specified 12
gallons.
HIGH TEMPERATURE OPERATION
At temperatures above 40°C(104°F), Welder output de-rating is
necessary. For maximum output ratings, de-rate the welder output 2
volts for every 10°C(50°F) above 40°C(104°F).
TOWING
The recommended trailer for use with this equipment for road, inplant and yard towing by a vehicle(1) is 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;
like maintenance.
5. Conformance with federal, state and local laws.

INSTALLATION
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 K1898-1 must be installed and properly maintained.
CAUTION
An incorrect spark arrestor may lead to damage to
the engine or adversely affect performance.
------------------------------------------------------------------------
HIGH FREQUENCY GENERATORS FOR
TIG APPLICATIONS
The K930-2 TIG Module is suitable for use with the
RANGER 305G. The RANGER 305G 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 305G is equipped with a 6-pin and a
14-pin 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 K963-3
hand Amptrol.
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
305G automatically switches the OUTPUT control
from control at the welder to remote control.
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 305G auto-sensing
circuit automatically makes the RANGER 305G
Output Control inactive and the wire feeder voltage
control active when the control cable is connected to
the 14-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:
WARNING
• Be grounded to the frame of the welder using a
grounded type plug.
• Be double insulated. Do not ground the machine
to a pipe that carries explosive or combustible
material.
------------------------------------------------------------------------
When this welder is mounted on a truck or trailer, its
frame must be electrically connected to the metal
frame of the vehicle, use a #8 or larger copper wire
connected between the machine grounding stud and
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.
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.
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.
RANGER 305G
WELDING TERMINALS
The RANGER 305G 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.

INSTALLATION
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.

The auxiliary power capacity is 10,000 watts Peak, 9500
Watts Continuous of 60 Hz, single phase power. The auxiliary power capacity rating in watts is equivalent to voltamperes at unity power factor. The max permissible current
of the 240 VAC output is 40 Amps. The 240 VAC output can
be split to provide two separate 120 VAC outputs with a max
permissible current of 40 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. All auxiliary power is protected by circuit breakers.
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, b u t
are of opposite polarities and cannot be paralleled.
STANDBY POWER CONNECTIONS
The RANGER 305G is suitable for temporary, standby or
emergency power using the engine manufacturer’s recommended maintenance schedule.
CABLE INSTALLATION
Install the welding cables to your RANGER 305G as
follows.
1. The engine must be OFF to install welding cables.
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 termi-
nals 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
The auxiliary power of the RANGER 305G 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 RANGER 305G can be permanently installed as a
standby power unit for 240 VAC, 3 wire, single phase, 40
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.
• 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.
• Take necessary steps to assure load is limited to the
capacity of the RANGER 305G by installing a 40 amp,
240 VAC double pole circuit breaker. Maximum rated
load for each leg of the 240 VAC auxiliary is 40 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 305G engine
and/or alternator windings.
• 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.)
• Plug this cable into the 50 Amp, 120/240 Volt receptacle
on the RANGER 305G case front.
