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.

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
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.
5.e. Also see item 1.b.

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.

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.

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.
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.
6. Eloigner les matériaux inflammables ou les recouvrir afin de prévenir tout risque d’incendie dû aux étincelles.
7. Quand on ne soud
e 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 debrancher à l’interrupteur à la boite de fusibles.
4. Garder tous les couvercles et dispositifs de sûreté à leur place.

MOVING PARTS can injure.
• Do not operate this equip­ment with any of its doors open or guards off.
• Stop the engine before ser­vicing it.
• Keep away from moving parts.
Only qualified personnel should install, use, or service this equipment.
LOCATION AND VENTILATION
Whenever you use the POWER-ARC 4000, be sure that clean cooling air can flow through the machine’s gasoline engine and the generator. Avoid dusty, dirty areas. Also, keep the machine away from heat sources. Do not place the back end of the generator anywhere near hot engine exhaust from another machine. And of course, make sure that engine exhaust is ventilated to an open, outside area.
The POWER-ARC 4000 may be used outdoors. Do not set the machine in puddles or otherwise sub­merge it in water. Such practices pose safety haz­ards and cause improper operation and corrosion of parts.
Always operate the POWER-ARC 4000 with the case roof on and all machine components completely assembled. This will protect you from the dangers of moving parts, hot metal surfaces, and live electrical devices.
STORING
1. Store the machine in a cool, dry place when it’s 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. If you will be storing the machine for over 30 days, you should drain the fuel to protect fuel system and carburetor parts from gum deposits. Empty all fuel from the tank and run the engine until it stops from lack of fuel.
3. You can store the machine for up to 24 months if you use Briggs & Stratton Gasoline Additive, Part No. 5041 (available from any Authorized Briggs & Stratton Service Center), in the fuel system. Mix the additive with the fuel in the tank and run the engine for a short time to circulate the additive through the carburetor.
4. While the engine is still warm, drain the oil and refill with fresh oil per the engine manual.
5. Remove the spark plug and pour approximately 1/2 ounce (15 ml) of engine oil into the cylinder. Replace the spark plug and crank the engine slowly to distribute the oil.
6. Clean any dirt and debris from the cylinder and cylinder head fins and housing, rotating screen, and muffler areas.

STACKING
POWER-ARC 4000 machines CANNOT be stacked.
TILTING
Place the machine on a secure, level surface whenev­er you use it or store it. Any surfaces you place it on other than the ground must be firm, non-skid, and structurally sound.
The gasoline engine is designed to run in a level posi­tion for best performance. It can operate at an angle, but this should never be more than 15 degrees in any direction. If you do operate it at a slight angle, be sure to check the oil regularly and keep the oil level full. Also, fuel capacity will be a little less at an angle.
LIFTING
The POWER-ARC 4000 should be lifted by two peo­ple. (It weighs 160 lbs/72.5 kg.) Its welded tube roll cage is designed to make lifting easy.
ANGLE OF OPERATION
Internal combustion engines are designed to run in a level condition to achieve optimum performance. The maximum angle of operation for the engine is 15 degrees from horizontal in any direction. Be certain to place the machine on a firm, non-skid, structural supporting surface. Anchor unit if necessary.
If you are operating the engine at a slight angle, be certain to check the oil regularly and maintain a level, full oil condition. The effective fuel capacity will also be slightly less than the specified 1.00 gallon (3.8 liters).
PRE-OPERATION ENGINE SERVICE
Read and understand the information about the gaso­line engine in the OPERATION and MAINTENANCE sections of this manual and the engine owner’s man­ual before you operate the POWER-ARC 4000.
• Keep hands away from the engine muffler or HOT engine parts.
• Stop the engine when fueling.
• Do not smoke when fueling.
• Remove the fuel cap slowly to release pressure.
• Do not overfill the fuel tank.
• Wipe up spilled fuel and allow the fumes to clear before starting the engine.
• Keep sparks and flame away from the fuel tank.
OIL
The Power-Arc 4000 with the Briggs and Stratton 8 HP engine produced after August 1998 and the Power-Arc 4000 with the Honda 9 HP engine are sup­plied with low oil shutdown protection. The Power­Arc 4000 with the Briggs and Stratton 8 HP engine produced before August 1998 is NOT equipped with an "Oil Gard"® low oil shutdown protection device. Oil must be regularly checked and added as needed. However, the engine block is equipped to accept an "Oil Gard"® accessory kit available from authorized Briggs and Stratton Distributors. An installed kit will sense low oil levels and will automatically shut down the engine. The engine cannot be restarted until suffi­cient oil is added.
The POWER-ARC 4000 is shipped with the engine filled with SAE 10W-30 oil. CHECK THE OIL LEVEL BEFORE YOU START THE ENGINE. This is an added precaution. When full, the oil level should be at the top of the fill plug hole. If it is not full, add enough oil to fill it. Be sure the fill plug is tight. Change oil after the first 5 hours of operation.
For more oil fill and service information, see the Engine owner’s manual.
FUEL
Fill the fuel tank with clean, fresh, regular grade lead-free gasoline. DO NOT MIX
OIL WITH THE GASOLINE.
The POWER-ARC 4000 has a fuel tank mounted on the engine. See the engine owner’s manual for more details about fuel.

MUFFLER DEFLECTOR
The POWER-ARC 4000, depending on model, may or may not be shipped with an exhaust deflector. If you received one, you can mount it on the gasoline engine if your needs so require.
To install the deflector, do the following:
• Align the holes on the deflector plate with the holes on the muffler.
Position the deflector so that the opening points either right, left, or downward, away from the operator.
Never position the deflector upward. Moisture or debris can enter the engine and damage it. As a general safety practice, position the deflector to direct exhaust gases away from the operator’s face and eyes.
• Fasten the deflector onto the muffler with the screws provided.
NOTE: The deflector reduces generator output
power up to 100 watts.
SPARK ARRESTER
Gasoline engine mufflers may emit sparks when the engine is running. Some federal, state, or local laws require spark arresters in locations where unarrested sparks could present a fire hazard.
Standard mufflers and deflectors (like the ones included with the POWER-ARC 4000 Briggs & Stratton engines) do not act as spark arresters. When local laws require it, a spark arrester must be installed on the machine and properly maintained
.
An optional spark arrester kit is available for your POWER-ARC 4000 Briggs & Stratton 8 HP Kool-Bore engine. See the ACCESSORIES section of this man­ual for more information.
An incorrect spark arrester may lead to damage to the engine or reduce performance. A suitable spark arrester for the Briggs & Stratton 8 HP Kool Bore
®
engine is available as a Lincoln field-
installed option.
A spark arrester is available for your POWER-ARC 4000 Briggs & Stratton 9 HP Vanguard engine from your local Briggs & Stratton engine dealer.
The Power-Arc 4000 with the Honda engine comes with a spark arrester as standard equipment. Refer to the engine owner’s manual for proper maintenance.

WELDING CABLE CONNECTIONS
Cable Size and Length
Be sure to use welding cables that are large enough. The correct size and length becomes especially important when you are welding at a distance from the welder.
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.

Cable Installation
Install the welding cables to your POWER-ARC 4000 as follows. See Figure A.1 for the location of parts.
1. The gasoline engine must be OFF to install weld­ing cables.
2. Remove the 1/2 - 13 flanged nuts from the output terminals.
3. Connect the electrode holder and work cables to the weld output terminals. You can connect either cable to either terminal, since the POWER­ARC 4000 provides AC weld current.
4. Tighten the flanged nuts securely.
5. Be certain that the metal piece you are welding (the “work”) is securely connected to the work clamp and cable.
6. Check and tighten the connections periodically.
• 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.
Lincoln Electric offers a welding accessory kit with the properly specified welding cables. See the ACCESSORIES section of this manual for more infor­mation.
MACHINE GROUNDING
Because the POWER-ARC 4000 creates its own power from its gasoline-engine driven generator, you do not need to connect the machine frame to an earth
ground. However, for best protection against electrical shock, connect a heavy gauge wire from the ground stud located on the bottom center of the output panel (see Figure A.1) to a suitable earth ground such as a metal pipe driven into the ground.
Do not ground the machine to a pipe that carries explosive or combustible material.
When the POWER-ARC 4000 is mounted on a truck or a trailer, the machine gen­erator ground stud MUST be securely connected to the metal frame of the vehicle. See Figure A.1. The ground stud is marked with the symbol.
PLUGS AND HAND-HELD EQUIPMENT
For further protection against electric shock, any electrical equipment connected to the generator receptacles must use a three-blade, grounded type plug or an Underwriter’s Laboratories (UL) approved double insulation system with a two-blade plug. Lincoln offers an accessory plug kit that has the right type of plugs. See the ACCESSORIES section of this manual for details.
Ground fault protection is needed for hand held equipment.
Never operate this machine with damaged or defec­tive cords. All electrical equipment must be in safe condition.
AUXILIARY POWER RECEPTACLES
The control panel of the POWER-ARC 4000 features two auxiliary power receptacles:
• A 20 amp, 120 volt duplex (double outlet) recepta­cle
• A 20 amp 240 volt simplex (single outlet) recepta­cle.
See Figure A.1.
Through these receptacles the machine can supply up to 4,000 rated continuous watts and 4,400 surge watts of single-phase AC power.

PREMISES WIRING
The POWER-ARC 4000 three-wire, grounded neutral generator allows it to be connected to premises wiring. However, the wiring procedure needed to meet the National Electric Code (NEC) regulations as well as city ordinances and can be confusing. The connections could vary from a "commonly grounded" to a "separately derived" system depending on whether you want the unit to be "hard wired" or tem­porary to the premises.
Only a licensed, certified, trained electrician should install the machine to a premises or resi­dential electrical system. Be certain that:
• The premises is isolated and no feed backing into the utility system can occur. Certain state and local laws require the premises to be isolat­ed before the generator is linked to the premis­es. Check your state and local requirements.
• A double pole, double throw transfer switch in conjunction with the properly rated double throw circuit breaker is connected between the generator power and the utility meter.
The POWER-ARC 4000 does not have a combined 120/240 volt twist-lock receptacle and cannot be connected to a premises as described in other Lincoln literature.
Remember that the POWER-ARC 4000 is intended only for backup, intermittent use power. Oil level must be checked after every 5 hours of use. The Briggs & Stratton engines used on the Power-Arc 4000 before August 1998 did not include a low oil shutdown option as standard equipment. It cannot withstand long-term use without proper maintenance. See the MAINTENANCE section of this manual and the engine owner’s manual for more information.
Certain electrical devices cannot be powered by the POWER-ARC 4000. Refer to Table A.2 for these devices.
CIRCUIT BREAKERS
The POWER-ARC 4000 has its own 20 amp circuit breakers for overload protection. When the machine is operated in high temperature environments, the breakers may tend to trip at lower loads than normal­ly.
Never bypass the circuit breakers. Without over­load protection, the power-arc 4000 could over­heat and/or cause damage to the equipment being used.
