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 cl othing. Wear dry, hol e-fre e
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

con dit ion s (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,
elect rode reel, welding head, nozzle or semiau tomat ic
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. N ev er simultaneously t ou ch electrically “ ho t” 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 . W hen w elding, keep
your head out of the fume. Use enough
ventilation and/or exhaust at the arc to keep
fumes and gases away from t he breathing zone. When

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 cour t-circuit accidental peut prov oquer 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. Protége r l’a utre perso nnel travail lant à p roximit é au
soudage à l’aide d’écrans appropriés et non-inflammables.
4. De s g outtes 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.

VRD (VOLTAGE REDUCTION DEVICE)
FIGURE A.1
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
DX450 machines cannot be stacked.
The VRD feature provides additional safety in the CC-Stick
mode especially in an environment with a higher risk of
electric shock such as wet areas and hot humid sweaty
conditions.
The VRD reduces the OCV (Open Circuit Voltage) at the
welding output terminals while not welding to less than 13V
DC when the resistance of the output circuit is above 200
(ohms).
The VRD requires that the welding cable connections be
kept in good electrical condition because poor connections
will contribute to poor starting. Having good electrical connections also limits the possibility of other safety issues
such as heat-generated damage, burns and fires.
The machine is shipped with the VRD switch in the “Off”
position. To turn it “On” or “Off”.
• Turn the engine “Off”.
• Disconnect the negative battery cable.
• Lower the control panel by removing 4 front
panel screws.
• Place the VRD switch in the “On” or “Off” position.
(See Figure A.1)
With the VRD switch in the “On” position, the VRD lights
are enabled.

DX450 (RED-D-ARC)
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 25
degrees in all directions, 35 degrees Intermittent (less
than 10 minutes continuous) in all directions. 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 amount
specified.
LIFTING
The DX450 weighs approximately 1391lbs. (631kg.)
with a full tank of fuel, 1245lbs. (565kg) less fuel. A lift
bail is mounted to the machine and should always be
used when lifting the machine.

pended from lift bail.
• DO NOT EXCEED MAXIMUM LIFT BAIL WEIGHT RATING. ( SEE TECHNICAL SPECIFICATIONS PAGE)
--------------------------------------------------------------------------------
HIGH ALTITUDE OPERATION
At higher altitudes, output derating may be necessary. For
maximum rating, derate the machine 1.0% for every 2000 ft.
(610m) up to 6000 ft. (1828m) and 2.0% for every 2000 ft.
(610m) over 6000 ft. (1828m). Due to new EPA and other
local emissions regulations, modifications to the engine for
high altitude are restricted within the United States. If
required contact an authorized Perkins engine field service
shop to determine if any adjustments can be made for operation in higher elevations.
HIGH TEMPERATURE OPERATION
At temperatures above 104°F(40°C), Welder output derating
is necessary. For maximum output ratings, derate the
weld e r outp u t 2 vo lts fo r every 18°F( 1 0 °C) ab o ve
104°F(40°C).
Cold weather starting:
With a fully charged battery and the proper oil, the
engine should start satisfactorily down to -15°F(26C°). If the engine must be frequently started at or
below 0°F (-18°C), it may be desirable to install coldstarting aides. The use of No. 1D diesel fuel is recommended in place of No. 2D at temperatures below
23°F (-5°C). Allow the engine to warm up before
applying a load or switching to high idle.
Note: Extreme cold weather starting may require
longer glow plug operation.
WARNING
Under no conditions should ether or other starting
fluids be used with this engine!
------------------------------------------------------------------------
TOWING
Use a recommended trailer for use with this equipment for road,
in-plant and yard towing by a vehicle(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 or damage the welding equipment. Some of the factors
to be considered are as follows:

CANADA only.
WARNING
• Fill the fuel tank with clean, fresh fuel. The capacity of
the tank is 20 gals. (75.7 ltrs). When the fuel gauge
reads empty the tank contains approximately 2 gals.
(7.6ltrs.) of reserve fuel.
NOTE: A fuel shut off valve is located on the pre-fil-
ter/sediment filter. Which should be in the closed
position when the welder is not used for extended periods of time.
------------------------------------------------------------------------
ENGINE COOLING SYSTEM
WARNING
Air to cool the engine is drawn in the side and exhausted through radiator & case back. It is important that the
intake and exhaust air is not restricted. Allow a minimum clearance of 1ft. (0.6m) from the case back and 16
in. (406mm) from either side of the base to a vertical
surface.
------------------------------------------------------------------------
BATTERY CONNECTION
CAUTION
Use caution as the electrolyte is a strong acid that can
burn skin and damage eyes.
------------------------------------------------------------------------
The DX450 is shipped with the negative battery cable disconnected. Make certain that the RUN-STOP switch is in
the STOP position. Remove the two screws from the battery
tray using a screwdriver or a 3/8"(10mm) socket. Attach the
negative battery cable to the negative battery terminal and
tighten using a 1/2"(13mm) socket or wrench.
NOTE: This machine is furnished with a wet charged
battery; if unused for several months, the battery may
require a booster charge. Be careful to charge the battery wi t h the correc t po l arity. (S e e Battery in
“Maintenance Section”)
MUFFLER OUTLET PIPE
Using the clamp provided secure the outlet pipe to the
outlet tube with the pipe positioned such that it will
direct the exhaust in the desired direction. Tighten
using a 9/16"(14mm) socket or wrench.
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.
A-4
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
K903-1 must be installed and properly maintained.
WARNING
An incorrect spark arrestor may lead to damage to
the engine or adversely affect performance.
------------------------------------------------------------------------
REMOTE CONTROL
The DX450 is equipped with a 3-pin and a 14-pin connect o r. When in the C C-STIC K , CV-WIR E OR
GOUGE modes and when a remote control is connected to the 3-pin Connector, the auto-sensing circuit
automatically switches the OUTPUT control from control at the welder to remote control.
When in TOUCH START TIG mode and when a
Amptrol is connected to the 3-Pin Connector, the
OUTPUT dial is used to set the maximum current
range of the CURRENT CONTROL of the Amptrol.
When in the DOWNHILL PIPE mode and when a
remote control is connected to the 3-Pin or 14-Pin
connector, the output control is used to set the maximum current range of the remote.
EXAMPLE: When the OUTPUT CONTROL on the
welder is set to 200 amps the current range on the
remote control will be 40-200 amps, rather than the
full 40-300 amps. Any current range that is less than
the full range provides finer current resolution for more
fine tuning of the output.
In the CV-WIRE mode, if the feeder being used has a
voltage control when the wire feeder control cable is
connected to the 14-Pin Connector, the auto-sensing
circuit automatically makes OUTPUT CONTROL inactive and the wir e feed er vol tage contro l acti ve.
Otherwise, the OUTPUT CONTROL is used to preset
the voltage.
The 14-pin connector is used to directly connect a
wire feeder control cable. In the CV-WIRE mode,
when the control cable is connected to the 14-pin connector, the auto-sensing circuit automatically makes
the Output Control inactive and the wire feeder voltage control active.
WARNING
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 3-pin connector.

INSTALLATION
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:
A-5
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"(19mm) 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.
WARNING
• Be grounded to the frame of the welder using a
grounded type plug or 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 bonded to the metal frame
of the vehicle. Use a #8 or larger copper wire connected between the machine grounding stud and the
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 instruction s i n t h e s ection e ntitle d " S tandby P ower
Connections" as well as the article on grounding in the
latest 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.

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 ter-
minal connection. Keep the cables isolated and
separate from one another.

AUXILIARY POWER RECEPTACLES
INSTALLATION
STANDBY POWER CONNECTIONS
A-6
Start the engine and set the “IDLER” control switch to the
“High Idle” mode. Voltage is now correct at the receptacles
for auxiliary power. This must be done before a tripped
GFCI module can be reset properly. See the MAINTENANCE section for more detailed information on testing
and resetting the GFCI module.
The auxiliary power of the DX450 consists of two 20 Amp120 VAC (5-20R) duplex receptacles with GFCI protection,
one 50 Amp 120/240 VAC (SS2-50R) receptacle and one
50 Amp 240VAC Three-Phase (15-50R) receptacle.
The auxiliary power capacity is 12,000 watts Peak, 11,000
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 50amps.
The 240 VAC output can be split to provide two separate
120 VAC outputs with a max permissible current of 50
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 Three-Phases auxiliary power capacity is 19,000 watts
peak, 17,000 watts continuous. The maximum current is 45
amps.
120 V DUPLEX RECEPTACLES AND GFCI MODULES
A GFCI Module protects the two 120V auxiliary power
receptacles.
The DX450 is suitable for temporary, standby or
emergency power using the engine manufacturer’s
recommended maintenance schedule.
The DX450 can be permanently installed as a standby
power unit for 240 VAC, 3 wire, single phase, 50 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.
• Ins t a ll the doubl e -pole, do u ble-th r ow 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 generator by installing a 50 amp,
240 VAC double pole circuit breaker. Maximum
rated load for each leg of the 240 VAC auxiliary is
50 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 engine and/or alternator windings.
• Install a 50 amp, 120/240 VAC plug to the doublepole circuit breaker using No. 6, 4 conductor cable
of the desired length.
A GFCI (Ground Fault Circuit Interrupter) is a device to protect against electric shock should a piece of defective
equipment connected to it develop a ground fault. If this situation should occur, the GFCI module will trip, removing
voltage from the output of the receptacle. If a GFCI module
is tripped see the MAINTENANCE section for detailed
information on testing and resetting it. A GFCI module
should be properly tested at least once every month.
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.
All auxiliary power is protected by circuit breakers. The
120V has 20 Amp circuit breakers for each duplex receptacle. The 120/240V Single Phase and the 240V ThreePhases have a 50 Amp 3-pole Circuit Breaker that disconnects both hot leads and all Three Phases simultaneously.
• Plug this cable into the 50 Amp, 120/240 Volt receptacle on the case front.
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 feedback into
the utility system can occur. Certain laws require
the premises to be isolated before the generator
is linked to the premises. Check your local
requirements.
