SECTION 1 − SAFETY PRECAUTIONS - READ BEFORE USING

som 2011−10

Protect yourself and others from injury — read, follow, and save these important safety precautions and operating instructions.

1-1. Symbol Usage

.

Indicates special instructions.

DANGER! − Indicates a hazardous situation which, if not avoided, will result in death or serious injury. The possible hazards are shown in the adjoining symbols or explained in the text.

Indicates a hazardous situation which, if not avoided, could result in death or serious injury. The possible hazards are shown in the adjoining symbols or explained in the text.

NOTICE − Indicates statements not related to personal injury.

1-2. Arc Welding Hazards

This group of symbols means Warning! Watch Out! ELECTRIC

SHOCK, MOVING PARTS, and HOT PARTS hazards. Consult symbols and related instructions below for necessary actions to avoid the 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.

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 Additional safety precautions are required when any of the following electrically hazardous conditions are present: 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; or when there is a high risk of unavoidable or accidental contact with the workpiece or ground. For these conditions, use the following equipment in order presented: 1) a semiautomatic DC constant voltage (wire) welder, 2) a DC manual

(stick) welder, or 3) an AC welder with reduced open-circuit voltage. In most situations, use of a DC, constant voltage wire welder is recommended. And, do not work alone!

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, ground, and operate 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 conductor first − double-check connections.

D Keep cords dry, free of oil and grease, and protected from hot metal and sparks.

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 Do not touch electrode holders connected to two welding machines at the same time since double open-circuit voltage will be present.

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. Disconnect cable for process not in use.

SIGNIFICANT DC VOLTAGE exists in inverter welding power sources AFTER removal of input power.

D Turn Off inverter, disconnect input power, and discharge input capacitors according to instructions in Maintenance Section before touching any parts.

HOT PARTS can burn.

D Do not touch hot parts bare handed.

D Allow cooling period before working on equipment.

D To handle hot parts, use proper tools and/or wear heavy, insulated welding gloves and clothing to prevent burns.

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

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

D If inside, ventilate the area and/or use local forced ventilation at the arc to remove welding fumes and gases.

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

D Read and understand 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 watchperson nearby. Welding fumes and gases can displace air and lower the oxygen level causing injury or death. Be sure the breathing air is safe.

D Do not weld in locations near degreasing, cleaning, or spraying operations. 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 while wearing an air-supplied respirator. The coatings and any metals containing these elements can give off toxic fumes if welded.

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 off from the weld.

D Wear an approved welding helmet fitted with a proper shade of filter lenses 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).

D Wear approved safety glasses with side shields under your helmet.

D Use protective screens or barriers to protect others from flash, glare and sparks; warn others not to watch the arc.

D Wear protective clothing made from durable, flame-resistant material (leather, heavy cotton, or wool) and foot protection.

WELDING can cause fire or explosion.

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.

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 Do not weld where flying sparks can strike flammable material.

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

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 containers that have held combustibles, or on closed containers such as tanks, drums, or pipes unless they are properly prepared according to AWS F4.1 and AWS A6.0 (see

Safety Standards).

D Do not weld where the atmosphere may contain flammable dust, gas, or liquid vapors (such as gasoline).

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, sparks, and fire hazards.

D Do not use welder to thaw frozen pipes.

OM-253 392 Page 2

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.

D After completion of work, inspect area to ensure it is free of sparks, glowing embers, and flames.

D Use only correct fuses or circuit breakers. Do not oversize or bypass them.

D Follow requirements in OSHA 1910.252 (a) (2) (iv) and NFPA 51B for hot work and have a fire watcher and extinguisher nearby.

FLYING METAL or DIRT 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 compressed gas supply when not in use.

D Always ventilate confined spaces or use approved air-supplied respirator.

ELECTRIC AND MAGNETIC FIELDS (EMF) can affect Implanted Medical Devices.

D Wearers of Pacemakers and other Implanted

Medical Devices should keep away.

D Implanted Medical Device wearers should consult their doctor and the device manufacturer before going near arc welding, spot welding, gouging, plasma arc cutting, or induction heating operations.

NOISE can damage hearing.

Noise from some processes or equipment can damage hearing.

D Wear approved ear protection if noise level is high.

CYLINDERS can explode if damaged.

Compressed 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.

D Protect compressed gas cylinders from excessive heat, mechanical shocks, physical damage, 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 compressed gas cylinders, regulators, hoses, and fittings 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 Use the right equipment, correct procedures, and sufficient number of persons to lift and move cylinders.

2-6. Informations relatives aux CEM

Le courant électrique qui traverse tout conducteur génère des champs

électromagnétiques (CEM) à certains endroits. Le courant de soudage crée un CEM autour du circuit et du matériel de soudage. Les CEM peuvent créer des interférences avec certains implants médicaux comme des stimulateurs cardiaques. Des mesures de protection pour les porteurs d’implants médicaux doivent être prises: Limiter par exemple tout accès aux passants ou procéder à une évaluation des risques individuels pour les soudeurs. Tous les soudeurs doivent appliquer les procédures suivantes pour minimiser l’exposition aux

CEM provenant du circuit de soudage:

1. Rassembler les câbles en les torsadant ou en les attachant avec du ruban adhésif ou avec une housse.

2. Ne pas se tenir au milieu des câbles de soudage. Disposer les câbles d’un côté et à distance de l’opérateur.

3. Ne pas courber et ne pas entourer les câbles autour de votre corps.

Weld current can damage electronic parts in vehicles.

Disconnect both battery cables before welding on a vehicle. Place work clamp as close to the weld as possible.

.

Always wear appropriate personal protective clothing.

1 Workpiece

Make sure workpiece is clean before 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 10-2).

4 Insulated Electrode Holder

5 Electrode Holder Position

6 Arc Length

Arc length is the distance from the electrode to 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.

11-2. Preparing Tungsten Electrode For DC Electrode Negative (DCEN) Welding

Or AC Welding With Inverter Machines

Grinding the tungsten electrode produces dust and flying sparks which can cause injury and start fires.

Use local exhaust (forced ventilation) at the grinder or wear an approved respirator. Read MSDS for safety information. Consider using tungsten containing ceria, lanthana, or yttria instead of thoria. Grinding dust from thoriated electrodes contains low-level radioactive material. Properly dispose of grinder dust in an environmentally safe way. Wear proper face, hand, and body protection. Keep flammables away.
