SECTION 1: Arc Welding Safety Instructions and Warnings
WARNING
ARC WELDING can be hazardous.
Protect yourself and others from possible serious injury or death. Keep children away. Do not lose
these instructions. Read operating / instruction manual before installing, operating or servicing this
product.
Welding products and welding processes can cause serious injury or death, or damage to other equipment or property, if the operator does not
strictly observe all safety rules and take precautionary actions.
Safe practices have developed from past experience in the use of welding and cutting. These practices must be learned through study and
training before using this equipment. Anyone not having extensive training in welding and cutting practices should not attempt to weld. Certain
practices apply to equipment connected to power lines; other practices apply to engine driven equipment.
Safe practices are out lined in the American National Standard Z49.1 entitled: SAFETY IN WELDING AND CUTTING. This publication and other
guides to what you should learn before operating this equipment are listed at the end of these safety precautions.
HAVE ALL INSTALLATION, OPERATION, MAINTENANCE, AND REPAIR WORK PERFORMED ONLY BY QUALIFIED PEOPLE.
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
terminal 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.
1. Do not touch live electrical parts.
2. Wear dry, hole-free insulating gloves and body protection.
3. Insulate yourself from work and ground using dry insulating
mats or covers.
4. Disconnect input power or stop engine before installing or
servicing this equipment. Lock input power disconnect switch
open, or remove line fuses so power cannot be turned on
accidentally.
5. Properly install and ground this equipment according to its
Owner's Manual and national, state, and 10 cal codes.
6. Turn off all equipment when not in use. Disconnect power to
equipment if it will be left unattended or out of service.
7. Use fully insulated electrode holders. Never dip holder in water to
cool it or lay it down on the ground or the work surface. Do not
touch holders connected to two welding machines at the same
time or touch other people with the holder or electrode.
8. Do not use worn, damaged, under sized or poorly spliced cables.
9. Do not wrap cables around your body.
10. Ground the workpiece to a good electrical (earth) ground.
11. Do not touch electrode while in contact with the work (ground)
circuit.
12. Use only well-maintained equipment. Repair or replace damaged
parts at once.
13. In confined spaces or damp locations, do not use a welder with
AC output unless it is equipped with a voltage reducer. Use
equipment with DC output.
14. Wear a safety harness to prevent falling if working above floor
level.
15. Keep all panels and covers securely in place.
ARC RAYS can burn eyes and skin;
NOISE can damage hearing.
Arc rays from the welding process produce intense
heat and strong ultraviolet rays that can burn eyes
and skin. Noise from some processes can damage
hearing.
1. Wear a welding helmet fitted with a proper shade of filter (see
ANSI 249.1 listed in Safety Standards) to protect your face and
eyes when welding or watching.
2. Wear approved safety glasses. Side shields recommended.
3. Use protective screens or barriers to protect others from flash
and glare; warn others not to watch the arc.
4. Wear protective clothing made from durable, flame-resistant
material (wool and leather) and foot protection.
5. Use approved earplugs or earmuffs if noise level is high.
FUMES AND GASES can be hazardous
to your health.
Welding produces fumes and gases. Breathing
these fumes and gases can be hazardous to your
health.
1. Keep your head out of the fumes. Do not breathe the fumes.
2. If inside, ventilate the area and/or use exhaust at the arc to
remove welding fumes and gases.
3. If ventilation is poor, use an approved air-supplied respirator.
4. Read the Material Safety Data Sheets (MSDS) and the
manufacturer's instruction for metals, consumables, coatings,
and cleaners.
5. Work in a confined space only if it is well ventilated, or while
wearing an air-supplied respirator. Shielding gases used for
welding can displace air causing injury or death. Be sure the
breathing air is safe.
6. Do not weld in locations near degreasing, cleaning, or spraying
operations. The heat and rays of the arc can react with vapours to
form highly toxic and irritating gases.
7. Do not weld on coated metals, such as galvanized lead, or
cadmium plated steel, unless the coating is re moved 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.
