WARNING

Mar ‘95

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.

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.

1.h. To avoid scalding, do not remove the

radiator pressure cap when the engine is

hot.

For Diesel Engines: Diesel engine exhaust and

some of its constituents are known to the State

of California to cause cancer, birth defects, and

other reproductive harm.

For Gasoline Engines: The engine exhaust from

this product contains chemicals known to the

State of California to cause cancer, birth defects,

or other reproductive harm.

CALIFORNIA PROPOSITION 65 WARNINGS

SAFETY

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.

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.

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

vapors

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.

5.e. Also see item 1.b.

Mar ‘95

FOR ELECTRICALLY

powered equipment.

8.a. Turn off input power using the disconnect

switch at the fuse box before working on

the equipment.

8.b. Install equipment in accordance with the U.S. National

Electrical Code, all local codes and the manufacturer’s

recommendations.

8.c. Ground the equipment in accordance with the U.S. National

Electrical Code and the manufacturer’s recommendations.

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.

SAFETY

iii

Mar ‘95

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.

Remember that welding sparks and hot

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

though

they have

been “cleaned”. For information, purchase “Recommended

Safe Practices for the

Preparation

for Welding and Cutting of

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.

6.f.

Sparks and spatter are thrown from the welding arc. Wear oil

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.

SAFETY

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 suiv-

antes:

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 met-

allique 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 defonc-

tionnement.

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.

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 rayon-

nement 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, pan-

talons 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.

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.

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 debranch-

er à l’interrupteur à la boite de fusibles.

4. Garder tous les couvercles et dispositifs de sûreté à leur place.

•Do not operate with doors open or

guards off.

•Stop engine before servicing.

•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.

DO NOT MOUNT OVER COMBUSTIBLE SURFACES

Where there is a combustible surface directly under sta-

tionary or fixed electrical equipment, that surface should

be covered with a steel plate at least .06”(1.6mm) thick,

which should extend not less than 5.90(150mm) beyond

the equipment on all sides.

STORING

1. Store the machine in a cool, dry place when it is not

in use. Protect it from dust and dirt. Keep it where it

can’t be accidentally damaged from construction

activities, moving vehicles, and other hazards.

2. Drain the engine oil and refill with fresh 10W30 oil.

Run the engine for about five minutes to circulate oil

to all the parts. See the MAINTENANCE section of

this manual for details on changing oil.

3. Remove the battery, recharge it, and adjust the elec-

trolyte level. Store the battery in a dry, dark place.

STACKING

COMMANDER 500 CUMMINS machines cannot be

stacked.

ANGLE OF OPERATION

To achieve optimum engine performance the COM-

MANDER 500 CUMMINS should be run in a level posi-

tion. The maximum angle of operation for the Cummins

engine is 35 degrees 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 specified 25 gallons.

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 ade-

quate lifting capacity.

• Be sure machine is stable when lift-

ing.

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

HIGH ALTITUDE OPERATION

At higher altitudes, output derating may be necessary.

For maximum rating, derate the welder output 4% for

every 300 meters (984 ft.) above 1500 meters (4920

ft.). For output of 500A and below, derate the welder

output 4% for every 300 meters (984 ft.) above 2100

meters (6888 ft.).

Contact a Cummins Service Representative for any

engine adjustments that may be required.

HIGH TEMPERATURE OPERATION

At temperatures above 40°C (104°F), output voltage

derating may be necessary. For maximum output cur-

rent ratings, derate welder voltage rating 2 volts for

every 10°C (21°F) above 40°C (104°F).

TOWING

The recommended trailer for use with this equipment

for road, in-plant and yard towing by a vehicle

(1)

Lincoln’s K953-1. If the user adapts a non-Lincoln trail-

er, he must assume responsibility that the method of

attachment and usage does not result in a safety haz-

ard 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

WELDING OUTPUT CABLES

With the engine off, route the electrode and work

cables thru the strain relief bracket provided on the

front of the base and connect to the terminals provid-

ed. These connections should be checked periodically

and tightened if necessary.

Listed in Table A.1 are copper cable sizes recom-

mended for the rated current and duty cycle. Lengths

stipulated are the distance from the welder to work and

back to the welder again. Cable sizes are increased for

greater lengths primarily for the purpose of minimizing

cable voltage drop.

Table A.1 Combined Length of Electrode and

Work Cables.

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

a) be grounded to the frame of the welder using a

grounded type plug,

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 con-

nected 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 sec-

tion 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.

AUXILIARY POWER RECEPTACLES

The auxiliary power capacity of the COMMANDER 500

CUMMINS is 12,000 watts of 60 Hz, single phase

power. The auxiliary power capacity rating in watts is

equivalent to volt-amperes at unity power factor. The

maximum permissible current of the 240 VAC output is

50 A. The 240 VAC output can be split to provide two

separate 120 VAC outputs with a maximum permissi-

ble current of 50 A per output to two separate 120 VAC

branch circuits. The output voltage is within ± 10% at

all loads up to rated capacity.

NOTE:

The 120/240V receptacle has two 120V outlets

of different phases and cannot be paralleled.

The Commander has two 20 Amp-120VAC (5-20R)

duplex receptacles 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 aux-

iliary power receptacles should only be used with three

wire grounded type plugs or approved double insulat-

ed 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.

STANDBY POWER CONNECTIONS

The COMMANDER 500 CUMMINS is suitable for tem-

porary, standby or emergency power using the engine

manufacturer’s recommended maintenance schedule.

The COMMANDER 500 CUMMINS can be perma-

nently installed as a standby power unit for 240 volt-3

wire, 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. The following information can be used as a

guide by the electrician for most applications. Refer to

the connection diagram shown in Figure A.2.

1. Install the double-pole, double-throw switch

between the power company meter and the premis-

es disconnect.

Switch rating must be the same or greater than the

customer’s premises disconnect and service over cur-

rent protection.

2. Take necessary steps to assure load is limited to the

capacity of the Commander by installing a 50 amp,

240 VAC double pole circuit breaker. Maximum

rated load for each leg of the 240 VAC auxiliary is 50

amps. 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 overheat-

ing of the COMMANDER 500 CUMMINS engine.

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.)

4. Plug this cable into the 50 Amp 120/240 Volt recep-

tacle on the COMMANDER 500 CUMMINS case

GENERAL DESCRIPTION

The COMMANDER 500 CUMMINS is a diesel engine-

driven welding power source. The machine uses a

brush type alternating current generator for DC multi-

purpose welding and for 120/240 VAC auxiliary stand-

by power. The welding control system uses state of the

art Chopper T

echnology. The COMMANDER 500

CUMMINS is not recommended for pipe thawing.

The generator has a single sealed bearing for mainte-

nance free service. The rotor is a copper wound design

with two slip rings and brushes. The stator is wound

entirely with heavy gauge copper wire and insulated

with NEMA class F insulation material. The stator is

then impregnated with three layers of high quality var-

nish. After the stator is assembled using tie bars, the

entire assembly covered with an environmentally pro-

tective coating. These measures insure trouble-free

operation in the harshest environments.

The fuel tank is made from high density polyethylene

and holds 25 gallons of diesel fuel. This will provide

enough fuel to run for more than 12 hours at full load.

The Cummins B3.3 engine is equipped with a stan-

dard, heavy duty, combination fuel filter/water separa-

tor element.

1. RUN STOP SWITCH

When placed in the “RUN” position, this switch ener-

gizes the fuel solenoid and other electric accessories.

When placed in the “STOP” position, the flow of fuel to

the injection pump is stopped to shut down the engine.

(Note: If the switch is left in the "RUN" position and the

engine is not running, the fuel solenoid will be engaged

for 15 seconds and then shut down. This is to protect

the battery from discharge. After 15 seconds, the Run

/ Stop switch must be toggled off then on before start-

ing.)

2. START PUSHBUTTON

Energizes the starter motor to crank the engine. With the

engine "Run / Stop" switch in the "Run" position, push and

hold the Start button to crank the engine; release as the

engine starts. Start button must be depressed for a minimum

of two seconds. Do not press while engine is running since

this can cause damage to the ring gear and/or starter motor.
