-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
electrode are electrically hot. 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.
-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 welding electrode
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 Amps output, use
a shade 10 lens; for above 160 Amps,
use a shade 12. Refer to the ANSI
standard Z87.1 for more information.
-Cover all bare skin areas exposed to
the arc with protective clothing and
shoes. Flame-retardant cloth or
