rom _nd_11/98

1-1. Symbol Usage

Means Warning! Watch Out! There are possible hazards with this procedure! The possible hazards are shown in the adjoining symbols.

 Marks a special safety message.

 Means “Note”; not safety related.

1-2. Arc Welding Hazards

 The symbols shown below are used throughout this manual to

call attention to and identify possible hazards. When you see the symbol, watch out, and follow the related instructions to avoid the hazard. The safety information given below is only a summary of the more complete safety information found in the Safety Standards listed in Section 1-5. Read and follow all Safety Standards.

 Only qualified persons should install, operate, maintain, and

repair this unit.

 During operation, keep everybody, especially children, away.

ELECTRIC SHOCK can kill.

Touching live electrical parts can cause fatal shocks or severe burns. The electrode and work circuit is electrically live whenever the output is on. The input

power circuit and machine internal circuits are also live when power is on. In semiautomatic or automatic wire welding, the wire, wire reel, drive roll housing, and all metal parts touching the welding wire are electrically live. Incorrectly installed or improperly grounded equipment is a hazard.

 Do not touch live electrical parts.  Wear dry, hole-free insulating gloves and body protection.  Insulate yourself from work and ground using dry insulating mats

or covers big enough to prevent any physical contact with the work or ground.

 Do not use AC output in damp areas, if movement is confined, or if

there is a danger of falling.

 Use AC output ONLY if required for the welding process.  If AC output is required, use remote output control if present on

unit.

 Disconnect input power or stop engine before installing or

servicing this equipment. Lockout/tagout input power according to OSHA 29 CFR 1910.147 (see Safety Standards).

 Properly install and ground this equipment according to its

Owner’s Manual and national, state, and local codes.

 Always verify the supply ground – check and be sure that input

power cord ground wire is properly connected to ground terminal in disconnect box or that cord plug is connected to a properly grounded receptacle outlet.

 When making input connections, attach proper grounding conduc-

tor first – double-check connections.

 Frequently inspect input power cord for damage or bare wiring –

replace cord immediately if damaged – bare wiring can kill.

 Turn off all equipment when not in use.  Do not use worn, damaged, undersized, or poorly spliced cables.  Do not drape cables over your body.  If earth grounding of the workpiece is required, ground it directly

with a separate cable.

 Do not touch electrode if you are in contact with the work, ground,

or another electrode from a different machine.

 Use only well-maintained equipment. Repair or replace damaged

parts at once. Maintain unit according to manual.

This group of symbols means Warning! Watch Out! possible ELECTRIC SHOCK, MOVING PARTS, and HOT PARTS hazards. Consult symbols and related instructions below for necessary actions to avoid the hazards.

 Wear a safety harness if working above floor level.  Keep all panels and covers securely in place.  Clamp work cable with good metal-to-metal contact to workpiece

or worktable as near the weld as practical.

 Insulate work clamp when not connected to workpiece to prevent

contact with any metal object.

 Do not connect more than one electrode or work cable to any

single weld output terminal.

SIGNIFICANT DC VOLTAGE exists after stopping engine on inverters.

 Stop engine on inverter and discharge input capacitors according

to instructions in Maintenance Section before touching any parts.

ARC RAYS can burn eyes and skin.

Arc rays from the welding process produce intense visible and invisible (ultraviolet and infrared) rays that can burn eyes and skin. Sparks fly of f from t h e weld.

 Wear a welding helmet fitted with a proper shade of filter to protect

your face and eyes from arc rays and sparks when welding or watching (see ANSI Z49.1 and Z87.1 listed in Safety Standards).

 Wear approved safety glasses with side shields under your

helmet.

 Use protective screens or barriers to protect others from flash and

glare; warn others not to watch the arc.

 Wear protective clothing made from durable, flame-resistant mate-

rial (wool and leather) and foot protection.

FUMES AND GASES can be hazardous.

Welding produces fumes and gases. Breathing these fumes and gases can be hazardous to your health.

 Keep your head out of the fumes. Do not breathe the fumes.  If inside, ventilate the area and/or use exhaust at the arc to remove

welding fumes and gases.

 If ventilation is poor, use an approved air-supplied respirator.  Read the Material Safety Data Sheets (MSDSs) and the

manufacturer’s instructions for metals, consumables, coatings, cleaners, and degreasers.

 Work in a confined space only if it is well ventilated, or while

wearing an air-supplied respirator. Always have a trained watchperson nearby. Welding fumes and gases can displace air and lower th e oxygen level causing injury or death. Be sure the breathing air is safe.

 Do not weld in locations near degreasing, cleaning, or spraying op-

erations. The heat and rays of the arc can react with vapors to form highly toxic and irritating gases.

 Do not weld on coated metals, such as galvanized, lead, or

cadmium plated steel, unless the coating is removed from the weld area, the area is well ventilated, and if necessary, while wearing an air-supplied respirator. The coatings and any metals containing these elements can give off toxic fumes if welded.

OM-945 Page 1

WELDING can cause fire or explo-

sion.

Welding on closed containers, such as tanks,

drums, or pipes, can cause them to blow up. Sparks

can fly off from the welding arc. The flying sparks, hot

workpiece, and hot equipment can cause fires and burns. Accidental contact of electrode to metal objects can cause sparks, explosion, overheating, or fire. Check and be sure the area is safe before doing any welding.

 Protect yourself and others from flying sparks and hot metal.  Do not weld where flying sparks can strike flammable material.  Remove all flammables within 35 ft (10.7 m) of the welding arc. If

this is not possible, tightly cover them with approved covers.

 Be alert that welding sparks and hot materials from welding can

easily go through small cracks and openings to adjacent areas.

 Watch for fire, and keep a fire extinguisher nearby.  Be aware that welding on a ceiling, floor, bulkhead, or partition can

cause fire on the hidden side.

 Do not weld on closed containers such as tanks, drums, or pipes,

unless they are properly prepared according to AWS F4.1 (see Safety Standards).

 Connect work cable to the work as close to the welding area as

practical to prevent welding current from traveling long, possibly unknown paths and causing electric shock and fire hazards.

 Do not use welder to thaw frozen pipes.  Remove stick electrode from holder or cut off welding wire at

contact tip when not in use.

 Wear oil-free protective garments such as leather gloves, heavy

shirt, cuffless trousers, high shoes, and a cap.

 Remove any combustibles, such as a butane lighter or matches,

from your person before doing any welding.

FLYING METAL can injure eyes.

 Welding, chipping, wire brushing, and grinding

cause sparks and flying metal. As welds cool, they can throw off slag.

 Wear approved safety glasses with side

shields even under your welding helmet.

BUILDUP OF GAS can injure or kill.

 Shut off shielding gas supply when not in use.  Always ventilate confined spaces or use ap-

proved air-supplied respirator.

HOT PARTS can cause severe burns.

 Allow cooling period before maintaining.  Wear protective gloves and clothing when

working on a hot engine.

 Do not touch hot engine parts or just-welded

parts bare-handed.

NOISE can damage hearing.

Noise from some processes or equipment can damage hearing.

 Wear approved ear protection if noise level is

high.

MAGNETIC FIELDS can affect pacemakers.

 Pacemaker wearers keep away.  Wearers should consult their doctor before

going near arc welding, gouging, or spot welding operations.

CYLINDERS can explode if damaged.

Shielding gas cylinders contain gas under high pressure. If damaged, a cylinder can explode. Since gas cylinders are normally part of the welding process, be sure to treat them carefully.

 Protect compressed gas cylinders from excessive heat, mechani-

cal shocks, slag, open flames, sparks, and arcs.

 Install cylinders in an upright position by securing to a stationary

support or cylinder rack to prevent falling or tipping.

 Keep cylinders away from any welding or other electrical circuits.  Never drape a welding torch over a gas cylinder.  Never allow a welding electrode to touch any cylinder.  Never weld on a pressurized cylinder – explosion will result.  Use only correct shielding gas cylinders, regulators, hoses, and fit-

tings designed for the specific application; maintain them and associated parts in good condition.

 Turn face away from valve outlet when opening cylinder valve.  Keep protective cap in place over valve except when cylinder is in

use or connected for use.

 Read and follow instructions on compressed gas cylinders,

associated equipment, and CGA publication P-1 listed in Safety Standards.

1-3. Engine Hazards

FUEL can cause fire or explosion.

 Stop engine and let it cool of f before checking or

adding fuel.

 Do not add fuel while smoking or if unit is near

any sparks or open flames.

 Do not overfill tank – allow room for fuel to expand.

 Do not spill fuel. If fuel is spilled, clean up before starting engine.

 Dispose of rags in a fireproof container.

OM-945 Page 2

STEAM AND HOT COOLANT can burn.

 If possible, check coolant level when engine is

cold to avoid scalding.

 Always check coolant level at overflow tank, if

present on unit, instead of radiator (unless told otherwise in maintenance section or engine manual).

1-6. EMF Information

Considerations About Welding And The Effects Of Low Frequency Electric And Ma g netic Fields

Welding current, as it flows through welding cables, will cause electromagnetic fields. There has been and still is some concern about such fields. However, after examining more than 500 studies spanning 17 years of research, a special blue ribbon committee of the National Research Council concluded that: “The body of evidence, in the committee’s judgment, has not demonstrated that exposure to power- frequency electric and magnetic fields is a human-health hazard.” However, studies are still going forth and evidence continues to be examined. Until the final conclusions of the research are reached, you may wish to minimize your exposure to electromagnetic fields when welding or cutting.

To reduce magnetic fields in the workplace, use the following procedures:

1. Keep cables close together by twisting or taping them.

2. Arrange cables to one side and away from the operator.

3. Do not coil or drape cables around your body.

4. Keep welding power source and cables as far away from operator as practical.

5. Connect work clamp to workpiece as close to the weld as possible.

About Pacemakers:

Pacemaker wearers consult your doctor first. If cleared by your doctor, then following the above procedures is recommended.

LE SOUDAGE peut provoquer un incendie ou une explosion.

DES PIÈCES CHAUDES peuvent provoquer des brûlures graves.

Le soudage effectué sur des conteneurs fermés tels que des réservoirs, tambours ou des conduites peut provoquer

l’arc de soudure. La projection d’étincelles, des pièces chaudes et des équipements chauds peut provoquer des incendies et des brûlures. Le contact accidentel de l’électrode avec des objets métalliques peut provoquer des étincelles, une explosion, un surchauffement ou un incendie. Avant de commencer le soudage, vérifier et s’assurer que l’endroit ne présente pas de danger.

 Se protéger et d’autres personnes de la projection d’étincelles et de métal

chaud.

 Ne pas souder dans un endroit là où des étincelles peuvent tomber sur des

substances inflammables.

 Déplacer toutes les substances inflammables à une distance de 10,7 m de

l’arc de soudage. En cas d’impossibilité les recouvrir soigneusement avec des protections homologués.

 Des étincelles et des matériaux chauds du soudage peuvent facilement

passer dans d’autres zones en traversant de petites fissures et des ouvertures.

 Surveiller tout déclenchement d’incendie et tenir un extincteur à proximité.  Le soudage effectué sur un plafond, plancher, paroi ou séparation peut dé-

clencher un incendie de l’autre côté.

 Ne pas effectuer le soudage sur des conteneurs fermés tels que des réser-

voirs, tambours, ou conduites, à moins qu’ils n’aient été préparés correctement conformément à AWS F4.1 (voir les normes de sécurité).

1-6. Information sur les champs électromagnétiques

Données sur le soudage électrique et sur les ef fets, pour l ’organisme, des champs magnétiques basse fréquence

Le courant de soudage, pendant son passage dans les câbles de soudage, causera des champs électromagnétiques. Il y a eu et il y a encore un certain souci à propos de tels champs. Cependant, après avoir examiné plus de 500 études qui ont été faites pendant une période de recherche de 17 ans, un comité spécial ruban bleu du National Research Council a conclu: “L’accumulation de preuves, suivant le jugement du comité, n’a pas démontré que l’exposition aux champs magnétiques et champs électriques à haute fréquence représente un risque à la santé humaine”. Toutefois, des études sont toujours en cours et les preuves continuent à être examinées. En attendant que les conclusions finales de la recherche soient établies, il vous serait souhaitable de réduire votre exposition aux champs électromagnéti- ques pendant le soudage ou le coupage.

Afin de réduire les champs électromagnétiques dans l’environnement de travail, respecter les consignes suivantes :

1 Garder les câbles ensembles en les torsadant ou en les

attachant avec du ruban adhésif.

2 Mettre tous les câbles du côté opposé de l’opérateur. 3 Ne pas courber pas et ne pas entourer pas les câbles autour de

votre corps.

4 Garder le poste de soudage et les câbles le plus loin possible de

vous.

5 Relier la pince de masse le plus près possible de la zone de

soudure.

Consignes relatives aux stimulateurs cardiaques :

Les personnes qui portent un stimulateur cardiaque doivent avant tout consulter leur docteur. Si vous êtes déclaré apte par votre docteur, il est alors recommandé de respecter les consignes ci–dessus.

1 Limit Load T o 90% Of

Generator Output

Always start non-resistive (motor) loads in order from largest to smallest, and add resistive loads last.

2 5 Second Rule If motor does not start within 5

seconds, turn off power to prevent motor damage. Motor requires more power than generator can supply.

SECTION 12 – STICK WELDING (SMAW) GUIDELINES

12-1. Stick Welding Procedure

 Weld current starts when

electrode touches workpiece.

 Weld current can damage

electronic parts in vehicles. Disconnect both battery cables before welding on a vehicle. P lace work clamp as close t o the weld as possible.

1 Workpiece Make sure workpiece is clean be-

fore welding. 2 Work Clamp 3 Electrode A small diameter electrode requires

less current than a large one. Follow electrode manufacturer’s instructions when setting weld amperage (see Section 12-2).

4 Insulated Electrode Holder 5 Electrode Holder Position 6 Arc Length Arc length is the distance from the

electrode t o the workpiece. A short arc with correct amperage will give a sharp, crackling sound.

7 Slag Use a chipping hammer and wire

brush to remove slag. Remove slag and check weld bead before making another weld pass.

Tools Needed:

12-14.Troubleshooting – Porosity

Porosity – small cavities or holes resulting from gas pockets in weld metal.

Possible Causes Corrective Actions

Arc length too long. Reduce arc length.

1 Vise 2 Weld Joint 3 Hammer

Strike weld joint in direction shown. A good weld bends over but does not break.

S-0057-B

Damp electrode. Use dry electrode. Workpiece dirty. Remove all grease, oil, moisture, rust, paint, coatings, slag, and dirt from work surface before

welding.

12-15.Troubleshooting – Excessive Spatter

Excessive Spatter – scattering of molten metal particles that cool to solid form near weld bead.

Possible Causes Corrective Actions

Amperage too high for electrode. Decrease amperage or select larger electrode. Arc length too long or voltage too high. Reduce arc length or voltage.

OM-945 Page 49

12-16.Troubleshooting – Incomplete Fusion

Incomplete Fusion – failure of weld metal to fuse completely with base metal or a preceeding weld bead.

Possible Causes Corrective Actions

Insufficient heat input. Increase amperage. Select larger electrode and increase amperage. Improper welding technique. Place stringer bead in proper location(s) at joint during welding.

Adjust work angle or widen groove to access bottom during welding. Momentarily hold arc on groove side walls when using weaving technique. Keep arc on leading edge of weld puddle.

Workpiece dirty. Remove all grease, oil, moisture, rust, paint, coatings, slag, and dirt from work surface before

welding.

12-17.Troubleshooting – Lack Of Penetration

Lack Of Penetration – shallow fusion between weld metal and base metal.

Lack of Penetration Good Penetration

Possible Causes Corrective Actions

Improper joint preparation. Material too thick. Joint preparation and design must provide access to bottom of groove. Improper weld technique. Keep arc on leading edge of weld puddle. Insufficient heat input. Increase amperage. Select larger electrode and increase amperage.

Reduce travel speed.

12-18.Troubleshooting – Excessive Penetration

Excessive Penetration – weld metal melting through base metal and hanging underneath weld.

Excessive Penetration

Possible Causes Corrective Actions

Excessive heat input. Select lower amperage. Use smaller electrode.

OM-945 Page 50

Good Penetration

Increase and/or maintain steady travel speed.

12-19.Troubleshooting – Burn-Through

Burn-Through – weld metal melting completely through base metal resulting in holes where no metal remains.

Possible Causes Corrective Actions

Excessive heat input. Select lower amperage. Use smaller electrode.

Increase and/or maintain steady travel speed.

12-20.Troubleshooting – Waviness Of Bead

Waviness O f Bead – weld metal that is not parallel and does not cover joint formed by base metal.

Possible Causes Corrective Actions

Unsteady hand. Use two hands. Practice technique.

12-21.Troubleshooting – Distortion

Distortion – contraction of weld met- al during welding that forces base metal t o move.

Base metal moves

in the direction of

the weld bead.

Possible Causes Corrective Actions

Excessive heat input. Use restraint (clamp) to hold base metal in position.

Make tack welds along joint before starting welding operation. Select lower amperage for electrode. Increase travel speed. Weld in small segments and allow cooling between welds.
