ARC WELDING SAFETY PRECAUTIONS
WARNING
- 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.
- 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.
- Only qualified persons should install, operate, maintain, and
repair this unit.
- During operation, keep everybody, especially children, away.
ARC WELDING can be hazardous.
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 equiment is a hazard.
1.- Do not touch live electrical parts.
2.- W ear 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.
5.- Properly install and ground this equipment according to this
Owner's Manual and national, state, and local codes.
6.- Turn off all equipment when not in use.
7.- Do not use worn, damaged, undersized, or poorly spliced cables.
8.- Do not wrap cables around your body.
9.- Ground the workpiece to a good electrical (earth) ground.
10.- Do not touch electrode while in contact with the work (ground)
circuit.
11.- Use only well-maintained equipment. Repair or replace damaged
parts at once.
12.- Wear a safety harness to prevent falling if working above floor
level.
13.- Keep all panels and cover 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 ANSIZ49.1 listed in Safety Standards) to protect
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 breath 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 (MSDSs) and the
manufacturer´s instruction for metal, 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 vapors 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 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.
FLYING SPARK AND HOT METAL can
cause injury
Chipping and grinding cause flying metal . As welds
cool, they can throw off slag.
1.- Wear approved face shield or safety goggles. Side shields
recommended.
2.- Wear proper body protection to protect skin.
your face and eyes when welding or watching.
2.- Wear approvedsafety glasses. Side shields recommended.
3.- Use protective screens or barriers to protect others from flash and
glade; warn others not to watch the arc.
4.- Wear protective clothing made from durable, flame- resistant mate
rial (wool and leather) and foot protection.
5.- Use approved ear plugs or ear muffs if noise level is high.
