cycles.
-Keep hands and fingers away from moving
parts and stay away from the drive rolls.
-Do not point torch at any body part of
yourself or anyone else.
-Always use this welder in the rated duty
cycle to prevent excessive heat and failure.
1.4 Specific Areas of Danger, Caution or
Warning Electrical Shock
Electric arc welders can produce
a shock that can cause injury or
death. Touching electrically live parts can
cause fatal shocks and severe burns. While
welding, all metal components connected to
the wire are electrically live. Poor ground
connections are a hazard, so secure the
ground lead before welding.
-Wear dry protective apparel: coat, shirt,
gloves and insulated footwear.
-Insulate yourself from the work piece.
Avoid contacting the work piece or ground.
- Do not attempt to repair or maintain the
welder while the power is on.
-Inspect all cables and cords for any
exposed wire and replace immediately if
found.
-Use only recommended replacement
cables and cords.
-Always attach ground clamp to the work
piece or work table as close to the weld
area as possible.
-Do not touch the torch and the ground or
grounded work piece at the same time.
-Do not use a welder to thaw frozen pipes.
Fumes and Gases
-Fumes emitted from the welding
process displace clean air and can
result in injury or death.
-Do not breathe in fumes emitted by the
welding process. Make sure your breathing
air is clean and safe.
-Work only in a well-ventilated area or use a
ventilation device to remove welding fumes
from the environment where you will be
working.
-Do not weld on coated materials
(galvanized, cadmium plated or containing
zinc, mercury or barium). They will emit
harmful fumes that are dangerous to
breathe. If necessary use a ventilator,
respirator with air supply or remove the
coating from the material in the weld area.
-The fumes emitted from some metals when
heated are extremely toxic. Refer to the
material safety data sheet for the
manufacturer’s instructions.
-Do not weld near materials that will emit
toxic fumes when heated. Vapors from
cleaners, sprays and degreasers can be
highly toxic when heated.
UV and IR Arc Rays
The welding arc produces
ultraviolet (UV) and infrared (IR)
rays that can cause injury to your eyes and
skin. Do not look at the welding arc without
proper eye protection.
-Always use a helmet that covers your full
face from the neck to top of head and to the
back of each ear.
-Use a lens that meets ANSI standards and
safety glasses. For welders under 160 amp
output, use a shade 10 lens; for above 160
amp, use a shade 12. Refer to the ANSI
standard Z87.1 for more information.

1901026-12
-Cover all bare skin areas exposed to the
arc with protective clothing and shoes.
Flame-retardant cloth or leather shirts,
coats, pants or coveralls are available for
protection.
-Use screens or other barriers to protect
other people from the arc rays emitted from
your welding.
-Warn people in your welding area when
you are going to strike an arc so they can
protect themselves.
Fire Hazards
Do not weld on containers or pipes
that contain or have had
flammable, gaseous or liquid combustibles
in them. Welding creates sparks and heat
that can ignite flammable and explosive
materials.
-Do not operate any electric arc in areas
where flammable or explosive materials are
present.
-Remove all flammable materials within 35
feet of the welding arc. If removal is not
possible, tightly cover them with fireproof
covers.
-Take precautions to ensure that flying
sparks do not cause fires or explosions in
hidden areas, cracks or areas you cannot
see.
-Keep a fire extinguisher close in the case
of fire.
-Wear garments that are oil-free with no
pockets or cuffs that will collect sparks.
-Do not have on your person any items that
are combustible, such as lighters or
matches.
-Keep work lead connected as close to the
weld area as possible to prevent any
unknown, unintended paths of electrical
current from causing electrical shock and
fire hazards.
Hot Materials
Welded materials are hot and can
cause severe burns if handled
improperly.
-Do not touch welded materials with bare
hands.
-Do not touch the torch after welding until it
has had time to cool down.
Sparks/Flying Debris
Welding creates hot sparks that
can cause injury. Chipping slag off
welds creates flying debris.
-Wear protective apparel at all times: ANSI-
approved safety glasses or shield, welder’s
hat and ear plugs to keep sparks out of ears
and hair. Electromagnetic Field
-Electromagnetic fields can
interfere with various electrical and
electronic devices such as pacemakers.
-Consult your doctor before using any
electric arc welder or cutting device.
-Keep people with pacemakers away from
your welding area when welding.
-Do not wrap cable around your body while
welding.
-Wrap the torch and ground cable together
whenever possible.
-Keep the torch and ground cables on the
same side of your body.
Shielding Gas Cylinders Can
Explode
High pressure cylinders can
explode if damaged, so treat them carefully.
-Never expose cylinders to high heat,
sparks, open flames, mechanical shocks or
arcs.
-Do not touch cylinder with the torch.
-Do not weld on the cylinder
