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 weld-
ing 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, coversand 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.

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 soud
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.
e pas, poser la pince à une endroit isolé de
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.

SAFETY PRECAUTIONS
WARNING
Do not attempt to use this equipment until you have
thoroughly read all operating and maintenance manuals supplied with your machine. They include important safety precautions, detailed engine starting,
operating and maintenance instructions and parts
lists.
ELECTRIC SHOCK can kill.
•Do not touch electrically live parts such
as output terminals or internal wiring.
•Insulate yourself from the work and
ground.
•Always wear dry insulating gloves.
------------------------------------------------------------------------
ENGINE EXHAUST can kill.
•Use in open, well ventilated areas or
vent exhaust outside
•Do not stack anything near the engine.
------------------------------------------------------------------------
MOVING PARTS can injure.
•Do not operate with doors open or
guards off.
•Stop engine before servicing.
STACKING
Commander 400 machines cannot be stacked.
ANGLE OF OPERATION
To achieve optimum engine performance the
Commander 400 should be run in a level position. The
maximum angle of operation for the Deutz engine is 20
degrees in a direction to cause the control panel to be
angled up, 30 degrees for side to side tilting and for the
control panel to be angled down. 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 25 gallons.
LIFTING
The Commander lift bale should be used to lift the
machine. The Commander is shipped with the lift bale
retracted. Before attempting to lift the Commander the
lift bale must be secured in a raised position. Secure
the lift bale as follows:
a. Open the engine compartment door.
b. Locate the 2 access holes on the upper middle
region of compartment wall just below the lift
bale.
c. Use the lifting strap to raise the lift bale to the full
upright position. This will align the mounting
holes on the lift bale with the access holes.
d. Secure the lift bale with 2 thread forming screws.
The screws are provided in the shipped loose
parts bag.
•Keep away from moving parts
------------------------------------------------------------------------
Only qualified personnel should install, use or service
this equipment
LOCATION/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.
COMMANDER 400
WARNING
FALLING EQUIPMENT can cause
injury.
•Do not lift this machine using lift bale if
it is equipped with a heavy accessory
such as a trailer or gas cylinder.
•Lift only with equipment of adequate
lifting capacity.

HIGH ALTITUDE OPERATION
At higher altitudes, output derating may be necessary.
As a rule of thumb, derate the welder output 5% for
every 400 meters (1312 ft.) above 1000 meters (3280
ft.).
Contact a Deutz Service Representative for any engine
adjustments that may be required for high altitude
operation.
TOWING
The recommended trailer for use with this equipment
for road, in-plant and yard towing by a vehicle
Lincoln’s K953-1. 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 that there will be no
undue stress to the trailer’s 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.
4. Typical conditions of use, such as travel speed,
roughness of surface on which the trailer will be
operated, and environmental conditions.
5. Proper preventative maintenance of trailer.
6. Conformance with federal, state and local laws.

OIL
The Commander is shipped with the engine crankcase
filled with high quality SAE 10W-30 oil (API class CD or
better). Check the oil level before starting the engine. If it
is not up to the full mark on the dip stick, add oil as
required. Check the oil level every four hours of running
time during the first 35 running hours. Refer to the engine
Operator’s Manual for specific oil recommendations and
break-in information. The oil change interval is dependent
on the quality of the oil and the operating environment.
Refer to the engine Operator’s Manual for the proper service and maintenance intervals.
FUEL USE DIESEL FUEL ONLY
Fill the fuel tank with clean, fresh diesel fuel. The capacity of the fuel tank is 25 gallons (94.6 liters). See engine
Operator’s Manual for specific fuel recommendations.
The Commander 400 is protected by a low fuel shutdown
to prevent the engine from running out of fuel. The
machine will indicate a low fuel condition by turning on the
low fuel light. A time of 30 minutes will elapse once the
low fuel light illuminates before the machine will shutdown. A restart of the machine will restart the timer to
allow the operator to override this feature. The amount of
reserve fuel remaining in the tank after the first shutdown
will vary from machine to machine. The operator must
determine the amount of fuel remaining before re-starting
the machine. Running out of fuel may require bleeding
the fuel injection pump.

acid that can burn skin and damage eyes.
Remove and discard the insulating cap from the negative battery terminal. Attach and tighten negative battery cable terminal.
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 with the correct polarity. Make sure that the battery is level while charging.
MUFFLER OUTLET PIPE
Remove the plastic plug covering the muffler outlet
tube. 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.
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
K899-1 must be installed and properly maintained.
CAUTION
An incorrect arrester may lead to damage to the engine
or adversely affect performance.

AUXILIARY POWER RECEPTACLES
The auxiliary power capacity of the Commander 400 is
10,000 watts of 60 Hz, single phase power. The auxiliary power capacity rating in watts is equivalent to voltamperes at unity power factor. The maximum permissible current of the 240 VAC output is 44 A. The 240
VAC output can be split to provide two separate 120
VAC outputs with a maximum permissible current of 44
A per output to two separate 120 VAC branch circuits.
The output voltage is within ± 10% at all loads up to
rated capacity.
NO
TE: The 120/240V receptacle has two 120V outlets
of different phases and cannot be paralleled.
The Commander has two 15 Amp-120VAC (5-15R)
duplex receptacles with GFCI protection and one 50
Amp-120/240 VAC (14-50R) receptacle. The 120/240
VAC receptacle can be split for single phase 120 VAC
operation. The 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.
To prevent dangerous electric shock, other equipment
powered by this engine driven welder must:
a) be grounded to the frame of the welder using a
grounded type plug,
or
b) be double insulated.
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
