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 1-4. Read and follow all Safety Standards.


Electric Shock can kill.electrical-circle.jpg

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.shock.png




  • 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 conductor 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 work-piece 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.




  • 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 work-piece or worktable as near the weld as practical.




  • Insulate work clamp when not connected to work-piece 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 removal of input power.


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


FUMES AND GASES can be hazardous.

inhalation.png
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 the oxygen level causing injury or death. Be sure the breathing air is safe.




  • 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.




  • 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.




  • Shut off shielding gas supply when not in use.



ARC RAYS can burn eyes and skin.

sparks.png

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.



  • 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 1.4).




  • 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 material (leather and 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 work-piece, 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.fire.png





  • 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, cuff less trousers, high shoes, and a cap.




  • Remove any combustibles, such as butane lighters or matches, from your person before doing any welding.



FLYING METAL can injure eyes.

debris.png


  • 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.


HOT PARTS can cause severe burns.

burn.png


  • Do not touch hot parts bare handed.




  • Allow cooling period before working on gun or torch.


MAGNETIC FIELDS can affect pacemakers.

magnetic.png


  • Pacemaker wearers keep away.




  • Wearers should consult their doctor before going near arc welding, gouging, or spot welding operations.

NOISE can damage hearing.

ears.png


  • Excessive noise from some processes or equipment can damage hearing.




  • Wear approved ear protection if noise level is high.

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.



explosive.png


  • Protect compressed gas cylinders from excessive heat, mechanical 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 fittings 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.

*As a rule of thumb, start with a shade that is too dark to see the weld zone. Then go to a lighter shade which gives sufficient view of the weld zone without going below the minimum.



1.7 Protective Clothing

Like other jobs or careers, welders must wear suitable protective equipment. In general, Personal Protective Equipment (PPE) must protect against hazards such as burns, sparks, spatter, electric shock, and radiation. The use of PPE is a good safe practice and may be required by regulatory agencies.




  • Wear clothing made from heavyweight, tightly woven, 100% wool or cotton to protect from UV radiation, hot metal, sparks and open flames. Flame retardant treatments become less effective with repeated laundering.

  • Keep clothing clean and free of oils, greases and combustible contaminants.

  • Wear long-sleeved shirts with buttoned cuffs and a collar to protect the neck. Dark colors prevent light reflection.

  • Tape shirt pockets closed to avoid collecting sparks or hot metal or keep them covered with flaps.

  • Pant legs must not have cuffs and must cover the tops of the boots. Cuffs can collect sparks.

  • Repair all frayed edges, tears or holes in clothing.

  • Wear high top boots fully laced to prevent sparks from entering into the boots.

  • Use fire-resistant boot protectors or spats strapped around the pant legs and boot tops, to prevent sparks from bouncing in the top of the boots.

  • Remove all ignition sources such as matches and butane lighters from pockets. Hot welding sparks may light the matches or ignite leaking lighter fuel.

  • Wear gauntlet-type cuff leather gloves or protective sleeves of similar material, to protect wrists and forearms. Leather is a good electrical insulator if kept dry.

  • Direct any spark spray away from your clothing.

  • Wear leather aprons to protect your chest and lap from sparks when standing or sitting.

  • Wear layers of clothing. To prevent sweating, avoid overdressing in cold weather. Sweaty clothes cause rapid heat loss. Leather welding jackets are not very breathable and can make you sweat if you are overdressed.

  • Wear a fire-resistant skull cap or balaclava hood under your helmet to protect your head from burns and UV radiation.

  • Wear a welder's face shield to protect your face from UV radiation and flying particles.

  • DO NOT wear rings or other jewelry.

  • DO NOT wear clothing made from synthetic or synthetic blends. The synthetic fabric can burn vigorously, melt and produce bad skin burns.

Protect all areas of your body from injury during welding or cutting by wearing the proper protective clothing and equipment.

Do not weld or cut unless wearing the necessary PPE as specified in this manual and in ANSI Z49.1.


1.8 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 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 work-piece 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.


1.9 General Precautionary Label

  • Trabajar en un espacio cerrado solamente si está bien ventilado o mientras esté usando un respirador con suministro de aire. Tenga siempre un watchperson capacitados cerca. Los humos y gases pueden desplazar el aire y bajar el nivel de oxígeno causando daño o la muerte. Asegúrese de que el aire respirable es seguro.




  • No suelde en lugares cerca de desengrase, limpieza o las operaciones de pulverización. El calor y los rayos del arco pueden hacer reacción con los vapores y formar gases altamente tóxicos e irritantes.




  • No suelde en materiales de recubrimientos, como galvanizado, plomo o acero cadmiado, a menos que el revestimiento se elimina del área de soldadura, la zona está bien ventilada, y si es necesario, mientras esté usando un respirador con suministro de aire. Los recubrimientos de cualquier metal que contiene estos elementos pueden emanar humos tóxicos cuando se sueldan.




  • Apague el protector cuando no suministro de gas en uso.


RAYOS DEL ARCO pueden quemar los ojos y la piel.sparks.png
Los rayos del arco del proceso de soldadura producen intensa visible e invisible (ultravioleta e infrarroja) que los rayos pueden quemar los ojos y la piel. Chispas se escapan de la soldadura.


  • Use una careta de soldar que tenga un matiz apropiado de filtro para proteger su cara y ojos mientras esté soldando o mirando (véase la norma ANSI Z49.1 y Z87.1 estándares de seguridad 1.4).




  • Use anteojos de seguridad con protección lateral debajo de su casc




  • Use pantallas de protección o barreras para proteger a otros del destello y el brillo, alerte a otros que no miren el arco.





SOLDAR puede causar fuego o explosión.

Soldando en un envase cerrado, como tanques, tambores o tubos, puede causar a volar. Las chispas pueden volar de un arco de soldadura. Las chispas que vuelan, el trabajo en caliente pieza, y el equipo caliente pueden causar fuegos y quemaduras. El contacto accidental del electrodo a objetos de metal puede causar chispas, explosión, sobrecalentamiento, o fuego. Revise y asegúrese que el área es segura antes de comenzar a soldar.fire.png




  • Protéjase y proteja a otros de las chispas y metal caliente.



  • No suelde donde las chispas pueden impactar material inflamable.



  • Quite todo material inflamable dentro de 35 pies (10,7 m) de la soldadura al arco.




  • Si esto no es posible, cúbralo apretadamente con cubiertas aprobadas.



  • Esté alerta de que chispas de soldar y materiales calientes de la soldadura puede pasar fácilmente a través de pequeñas grietas y aberturas en las zonas adyacentes.



  • Tenga cuidado con el fuego, y mantenga un extinguidor de fuego cerca.




  • Tenga en cuenta que la soldadura en el techo, piso, pared o partición puede causar fuego en la cara oculta.




  • No suelde en receptáculos cerrados como tanques, tambores o tubería, a menos que estén debidamente preparados de acuerdo con AWS F4.1 (véase normas de seguridad).




  • Conecte el cable de trabajo a la labor tan cerca de la zona de soldadura como sea posible para evitar que la corriente de soldadura de viajar rutas de largo, posiblemente por partes desconocidas causando una descarga eléctrica y peligro de incendio.




  • No use una soldadora para descongelar tubos helados.




  • Retire electrodo de varilla de soporte o corte el alambre de soldadura cuando no en la punta de contacto en el uso.




  • Use ropa protectiva sin aceite como guantes de cuero, camisa gruesa, gemelos menos los pantalones, los zapatos de bebé, y una gorra.




  • Retire todo material combustible, tales como encendedores de butano o fósforos, de su persona antes de comenzar a soldar.


METAL QUE VUELA pueden lesionar los ojos.debris.png

• soldar, picar, cepillar con alambre, y las chispas causa de pulido y metal que vuele. Como se enfrían las sueldas, estás pueden soltar escoria.

• Use anteojos de seguridad con resguardos laterales hasta debajo de su careta.
