Shielded Metal Arc Welder
General Safety
(Continued)
G Before starting or servicing any electric
arc welder, read and understand all
instructions. Failure to follow safety
precautions or instructions can cause
equipment damage and or serious
personal injury or death.
G All installation, maintenance, repair
and operation of this equipment
should be performed by qualified
persons only in accordance with
national, state, and local codes.
WARNING
!
Improper use of electric arc
welders can cause electric
shock, injury, and death! Take
all precautions described in this manual
to reduce the possibility of electric shock.
G Verify that all components of the arc
welder are clean and in good
condition prior to operating the
welder. Be sure that the insulation
on all cables, electrode holders, and
power cords is not damaged. Always
repair or replace damaged
components before operating the
welder. Always keep welder panels,
shields, etc. in place when operating
the welder.
G Always wear dry protective clothing
and welding gloves, and insulated
footwear.
G Always operate the welder in a clean,
dry, well ventilated area. Do not
operate the welder in humid, wet,
rainy, or poorly ventilated areas.
G Be sure that the work piece is
properly supported and grounded
prior to beginning any electric arc
welding operation.
G Coiled welding cable should be
spread out before use to avoid
overheating and damage to
insulation.
Never immerse the

electrode or
electrode holder in water. If the welder
becomes wet for any reason, be
absolutely certain that it is completely
clean and dry prior to attempting use!
G Always shut the equipment off and
unplug the power prior to moving
the unit.
G Always attach the work lead first.

G Verify that the work piece is
securely grounded.
G Always shut off electric arc welding
equipment when not in use and
remove the electrode from the holder.
G Never allow any part of the body to
touch the electrode and ground or
grounded work piece at the same time.
G Awkward welding conditions and
positions can be electrically hazardous.
When crouching, kneeling or at
elevations, be sure to insulate all
conductive parts, wear appropriate
protective clothing, and take
precautions to prevent injury from falls.
G Never attempt to use this
equipment at current settings or
duty cycles higher than those
specified on the equipment labels.
G Never use an electric arc welder to
thaw frozen pipes.
WARNING
!
Flying sparks and hot metal
can cause injury. As welds
cool, slag can be thrown off.
Take all precautions described in this
manual to reduce the possibility of
injury from flying sparks and hot metal.
G Wear ANSI approved face shield or
safety glasses with side shield
protection when chipping or
grinding metal parts.
G Wear ear plugs when welding
overhead to prevent spatter or slag
from falling into ears.
WARNING
!
Electric arc welding operations
produce intense light and heat
and ultraviolet (UV) rays. This
intense light and UV rays can cause injury
to eyes and skin. Take all precautions
described in this manual to reduce the
possibility of injury to eyes and skin.
G All persons operating this
equipment or in the area while
equipment is in use must wear
protective welding gear including:
welding helmet or shield with at
least shade 10, flame resistant
clothing, leather welding gloves,
and full foot protection.
WARNING
!
Never look at arc
welding operations without eye
protection as described above. Never
use a shade filter lens that is cracked,
broken, or rated below number 10.
Warn others in the area not to look at
the arc.

WARNING
!
Electric arc welding
operations cause sparks
and heat metal to
temperatures that can cause severe
burns! Use protective gloves and
clothing when performing any metal
working operation. Take all precautions
described in this manual to reduce the
possibility of skin and clothing burns.
G Make sure that all persons in the
welding area are protected from
heat, sparks, and ultraviolet rays.
Use additional face shields and
flame resistant barriers as needed.
G Never touch work pieces until
completely cooled.
WARNING
!
Heat and sparks produced during
electric arc welding and other metal
working operations can ignite
flammable and explosive materials!
Take all precautions described in this
manual to reduce the possibility of
flames and explosions.
G Remove all flammable
materials within 35 feet
(10.7 meters) of welding
arc. If removal is not
possible, tightly cover flammable
materials with fire proof covers.
G Do not operate any electric arc
welder in areas where flammable or
explosive vapors may be present.
G Take precautions to be sure that
flying sparks and heat do not cause
flames in hidden areas, cracks,
behind bulkheads, etc.
WARNING
!
Fire hazard! Do not weld on
containers or pipes that
contain or have contained
flammable materials or gaseous or
liquid combustibles.
WARNING
!
Arc welding closed cylinders
or containers such as tanks
or drums can cause
explosion if not properly vented!
Verify that any cylinder or container to
be welded has an adequate ventilation
hole, so that expanding gases can be
released.
