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.
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.
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.
5
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 contact 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.
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, 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.
6
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.
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
Standards1.4).
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 mental
objects can cause sparks, explosion, overheating, or fire. Check and be sure the area is
safe before doing any welding.
Protect yourself and others from flying sparks and hot metal.
Do not weld where flying sparks can strike flammable material.
Removal all flammables within 35ft. (10.7m) 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 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
7
before doing any welding
FLYING MENTAL can injure eyes.
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.
Do not touch hot bare handed.
Allow cooling period before working on gun or torch.
MAGNETIC FIELDS can affect pacemakers.
Pacemaker wearers keep away.
Wearers should consult their doctor before going near arc welding, gouging, or
spot welding operations.
NOISE can damage hearing.
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.
8
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 torch 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 use or connected for use.
Read and follow instruction on compressed gas cylinders,
associated equipment , and CGA publication P-1listed in
Safety Standards.
