1-2. Arc Welding Hazards

Y 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 1-4. Read and follow all

Safety Standards.

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

repair this unit.

Y 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.

D Do not touch live electrical parts.

D Wear dry, hole-free insulating gloves and body protection.

D Insulate yourself from work and ground using dry insulating mats

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

or ground.

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

there is a danger of falling.

D Use AC output ONLY if required for the welding process.

D If AC output is required, use remote output control if present on

unit.

D 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).

D Properly install and ground this equipment according to its

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

D 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.

D When making input connections, attach proper grounding conduc-

tor first – double-check connections.

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

replace cord immediately if damaged – bare wiring can kill.

D Turn off all equipment when not in use.

D Do not use worn, damaged, undersized, or poorly spliced cables.

D Do not drape cables over your body.

D If earth grounding of the workpiece is required, ground it directly

with a separate cable.

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

or another electrode from a different machine.

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

parts at once. Maintain unit according to manual.

D Wear a safety harness if working above floor level.

D Keep all panels and covers securely in place.

D Clamp work cable with good metal-to-metal contact to workpiece

or worktable as near the weld as practical.

D Insulate work clamp when not connected to workpiece to prevent

contact with any metal object.

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

single weld output terminal.

SIGNIFICANT DC VOLTAGE exists after removal of

input power on inverters.

D Turn Off inverter, disconnect input power, and discharge input

capacitors according to instructions in Maintenance Section

before touching any parts.

Welding produces fumes and gases. Breathing

these fumes and gases can be hazardous to your

health.

FUMES AND GASES can be hazardous.

D Keep your head out of the fumes. Do not breathe the fumes.

D If inside, ventilate the area and/or use exhaust at the arc to remove

welding fumes and gases.

D If ventilation is poor, use an approved air-supplied respirator.

D Read the Material Safety Data Sheets (MSDSs) and the

manufacturer’s instructions for metals, consumables, coatings,

cleaners, and degreasers.

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

wearing an air-supplied respirator. Always have a trained watch-

person nearby. Welding fumes and gases can displace air and

lower the oxygen level causing injury or death. Be sure the breath-

ing air is safe.

D 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.

D 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-1311 Page 2

Arc rays from the welding process produce intense

visible and invisible (ultraviolet and infrared) rays

that can burn eyes and skin. Sparks fly off from the

weld.

ARC RAYS can burn eyes and skin.

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

your face and eyes when welding or watching (see ANSI Z49.1

and Z87.1 listed in Safety Standards).

D Wear approved safety glasses with side shields under your

helmet.

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

glare; warn others not to watch the arc.

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

rial (leather and wool) and foot protection.

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.

WELDING can cause fire or explosion.

D Protect yourself and others from flying sparks and hot metal.

D Do not weld where flying sparks can strike flammable material.

D Remove all flammables within 35 ft (10.7 m) of the welding arc. If

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

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

easily go through small cracks and openings to adjacent areas.

D Watch for fire, and keep a fire extinguisher nearby.

D Be aware that welding on a ceiling, floor, bulkhead, or partition can

cause fire on the hidden side.

D 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).

D 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.

D Do not use welder to thaw frozen pipes.

D Remove stick electrode from holder or cut off welding wire at

contact tip when not in use.

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

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

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

from your person before doing any welding.

FLYING METAL can injure eyes.

D Welding, chipping, wire brushing, and grinding

cause sparks and flying metal. As welds cool,

they can throw off slag.

D Wear approved safety glasses with side

shields even under your welding helmet.

BUILDUP OF GAS can injure or kill.

D Shut off shielding gas supply when not in use.

D Always ventilate confined spaces or use

approved air-supplied respirator.

HOT PARTS can cause severe burns.

D Do not touch hot parts bare handed.

D Allow cooling period before working on gun or

torch.

MAGNETIC FIELDS can affect pacemakers.

D Pacemaker wearers keep away.

D Wearers should consult their doctor before

going near arc welding, gouging, or spot

welding operations.

NOISE can damage hearing.

Noise from some processes or equipment can

damage hearing.

D Wear approved ear protection if noise level is

high.

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.

CYLINDERS can explode if damaged.

D Protect compressed gas cylinders from excessive heat, mechani-

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

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

support or cylinder rack to prevent falling or tipping.

D Keep cylinders away from any welding or other electrical circuits.

D Never drape a welding torch over a gas cylinder.

D Never allow a welding electrode to touch any cylinder.

D Never weld on a pressurized cylinder – explosion will result.

D Use only correct shielding gas cylinders, regulators, hoses, and fit-

tings designed for the specific application; maintain them and

associated parts in good condition.

D Turn face away from valve outlet when opening cylinder valve.

D Keep protective cap in place over valve except when cylinder is in

use or connected for use.

D Read and follow instructions on compressed gas cylinders,

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

Standards.

1-5. EMF Information

Considerations About Welding And The Effects Of Low Frequency

Electric And Magnetic Fields

Welding current, as it flows through welding cables, will cause electro-

magnetic 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 opera-

tor as practical.

5. Connect work clamp to workpiece as close to the weld as possi-

ble.

About Pacemakers:

Pacemaker wearers consult your doctor first. If cleared by your doctor,

then following the above procedures is recommended.

1-5. Information sur les champs électromagnétiques

Données sur le soudage électrique et sur les effets, pour l’organisme,

des champs magnétiques basse fréquence

Le courant de soudage, pendant son passage dans les câbles de sou-

dage, causera des champs électromagnétiques. Il y a eu et il y a encore

un certain souci à propos de tels champs. Cependant, après avoir ex-

aminé plus de 500 études qui ont été faites pendant une période de

recherche de 17 ans, un comité spécial ruban bleu du National Re-

search 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 con-

clusions 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

Duty Cycle is percentage of 10 min-

utes that unit can weld at rated load

without overheating.

If unit overheats, thermostat(s)

opens, output stops, and cooling

fan runs. Wait fifteen minutes for

unit to cool. Reduce amperage or

voltage, or duty cycle before

welding.
