BE SURE THAT ALL INSTALLATION, OPERATION,MAINTENANCE AND REPAIR PROCEDURES AREPERFORMED ONLY BY QUALIFIED INDIVIDUALS.

FOR ENGINE POWEREDEQUIPMENT.

1.a. Turn the engine off before troubleshootingand maintenance work unless themaintenance work requires it to be running.

1.b. Operate engines in open, well-ventilatedareas or vent the engine exhaust fumes outdoors.

1.c. Do not add the fuel near an open flamewelding arc or when the engine is running.Stop the engine and allow it to cool beforerefueling to prevent spilled fuel fromvaporizing on contact with hot engine partsand igniting. Do not spill fuel when fillingtank. If fuel is spilled, wipe it up and do not start engine untilfumes have been eliminated.

1.d. Keep all equipment safety guards, covers anddevices in position and in good repair.Keephands, hair, clothing and tools away from V-belts, gears, fans and all other moving partswhen starting, operating or repairingequipment.

1.e. In some cases it may be necessary to remove safety guards toperform required maintenance. Remove guards only whennecessary and replace them when the maintenance requiringtheir removal is complete. Always use the greatest care whenworking near moving parts.

1.f. Do not put your hands near the engine fan. Do not attempt tooverride the governor or idler by pushing on the throttle controlrods while the engine is running.

1.g. To prevent accidentally starting gasoline engines while turningthe engine or welding generator during maintenance work,disconnect the spark plug wires, distributor cap or magneto wireas appropriate.

1.h. To avoid scalding, do not remove the radiatorpressure cap when the engine is hot.

ELECTRIC ANDMAGNETIC FIELDS MAYBE DANGEROUS

2.a. Electric current flowing through any conductorcauses localized Electric and Magnetic Fields (EMF). Weldingcurrent creates EMF fields around welding cables and weldingmachines

2.b. EMF fields may interfere with some pacemakers, and weldershaving a pacemaker should consult their physician beforewelding.

2.c. Exposure to EMF fields in welding may have other health effectswhich are now not known.

2.d. All welders should use the following procedures in order tominimize exposure to EMF fields from the welding circuit:

2.d.1. Route the electrode and work cables together - Securethem 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 workcables. If the electrode cable is on your right side, thework cable should also be on your right side.

2.d.4. Connect the work cable to the workpiece as close as pos-sible to the area being welded.

2.d.5. Do not work next to welding power source.

SAFETY

Page 4: IM278 NA-3N - Lincoln Electric

ELECTRIC SHOCK CAN KILL.

3.a. The electrode and work (or ground) circuits areelectrically “hot” when the welder is on. Donot touch these “hot” parts with your bare skinor 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 areaof 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 weldinggun are also electrically “hot”.

3.d. Always be sure the work cable makes a good electricalconnection with the metal being welded. The connection shouldbe 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 andwelding machine in good, safe operating condition. Replacedamaged insulation.

3.g. Never dip the electrode in water for cooling.

3.h. Never simultaneously touch electrically “hot” parts of electrodeholders connected to two welders because voltage between thetwo can be the total of the open circuit voltage of bothwelders.

3.i. When working above floor level, use a safety belt to protectyourself from a fall should you get a shock.

3.j. Also see It ems 6.c. and 8.

ARC RAYS CAN BURN.

4.a. Use a shield with the proper filter and cover plates to protect youreyes from sparks and the rays of the arc when welding orobserving open arc welding. Headshield and filter lens shouldconform to ANSI Z87. I standards.

4.b. Use suitable clothing made from durable flame-resistant materialto protect your skin and that of your helpers from the arc rays.

4.c. Protect other nearby personnel with suitable, non-flammablescreening and/or warn them not to watch the arc nor exposethemselves to the arc rays or to hot spatter or metal.

FUMES AND GASESCAN BE DANGEROUS.

5.a. Welding may produce fumes and gaseshazardous to health. Avoid breathing thesefumes 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 within applicable osha Pel and

aCgih tlV limits 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. The operation of welding fume control equipment is affected byvarious factors including proper use and positioning of theequipment, maintenance of the equipment and the specificwelding procedure and application involved. Worker exposurelevel should be checked upon installation and periodicallythereafter to be certain it is within applicable OSHA PEL andACGIH TLV limits.

5.c. Do not weld in locations near chlorinated hydrocarbon vaporscoming from degreasing, cleaning or spraying operations. Theheat and rays of the arc can react with solvent vapors to formphosgene, a highly toxic gas, and other irritating products.

5.d. Shielding gases used for arc welding can displace air and causeinjury or death. Always use enough ventilation, especially inconfined areas, to insure breathing air is safe.

5.e. Read and understand the manufacturer’s instructions for thisequipment and the consumables to be used, including thematerial safety data sheet (MSDS) and follow your employer’ssafety practices. MSDS forms are available from your weldingdistributor or from the manufacturer.

5.f. Also see item 1.b.

SAFETY

Page 5: IM278 NA-3N - Lincoln Electric

WELDING AND CUTTINGSPARKS CAN CAUSEFIRE OR EXPLOSION.

6.a. Remove fire hazards from the welding area. Ifthis is not possible, cover them to prevent thewelding sparks from starting a fire. Remember that weldingsparks and hot materials from welding can easily go throughsmall cracks and openings to adjacent areas. Avoid welding nearhydraulic lines. Have a fire extinguisher readily available.

6.b. Where compressed gases are to be used at the job site, specialprecautions 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 istouching the work or ground. Accidental contact can causeoverheating and create a fire hazard.

6.d. Do not heat, cut or weld tanks, drums or containers until theproper steps have been taken to insure that such procedures willnot cause flammable or toxic vapors from substances inside.They can cause an explosion even though they have been“cleaned”. For information, purchase “Recommended SafePractices for the Preparation for Welding and Cutting ofContainers and Piping That Have Held Hazardous Substances”,AWS F4.1 from the American Welding Society (see addressabove).

6.e. Vent hollow castings or containers before heating, cutting orwelding. They may explode.

6.f. Sparks and spatter are thrown from the welding arc. Wear oil freeprotective garments such as leather gloves, heavy shirt, cufflesstrousers, high shoes and a cap over your hair. Wear ear plugswhen welding out of position or in confined places. Always wearsafety glasses with side shields when in a welding area.

6.g. Connect the work cable to the work as close to the welding areaas practical. Work cables connected to the building framework orother locations away from the welding area increase thepossibility of the welding current passing through lifting chains,crane cables or other alternate circuits. This can create firehazards or overheat lifting chains or cables until they fail.

6.h. Also see item 1.c.

6.I. Read and follow NFPA 51B “ Standard for Fire Prevention DuringWelding, Cutting and Other Hot Work”, available from NFPA, 1Batterymarch Park, PO box 9101, Quincy, Ma 022690-9101.

6.j. Do not use a welding power source for pipe thawing.

CYLINDER MAY EXPLODE IFDAMAGED.

7.a. Use only compressed gas cylinders containingthe correct shielding gas for the process usedand properly operating regulators designed forthe gas and pressure used. All hoses, fittings,etc. should be suitable for the application andmaintained in good condition.

7.b. Always keep cylinders in an upright position securely chained toan undercarriage or fixed support.

7.c. Cylinders should be located:

• Away from areas where they may be struck or subjectedto physical damage.

• A safe distance from arc welding or cutting operationsand any other source of heat, sparks, or flame.

7.d. Never allow the electrode, electrode holder or any otherelectrically “hot” parts to touch a cylinder.

7.e. Keep your head and face away from the cylinder valve outletwhen opening the cylinder valve.

7.f. Valve protection caps should always be in place and hand tightexcept 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 forSafe Handling of Compressed Gases in Cylinders,” availablefrom the Compressed Gas Association 1235 Jefferson DavisHighway, Arlington, VA 22202.

FOR ELECTRICALLYPOWERED EQUIPMENT.
