proved method for eliminating the
hazard.
Do not dispose of hot slag in con-
tainers holding combustible materi-
als. Keep a re extinguisher nearby
and know how to use it.
After spot welding, make a thorough
examination for evidence of re. Be
aware that easily-visible smoke or
ame may not be present for some
time after the re has started. Do
not weld or cut in atmospheres
containing dangerously reactive or
ammable gases, vapors, liquids,
and dust. Provide adequate ven-
tilation in work areas to prevent
accumulation of ammable gases,
vapors, and dust. Do not apply
heat to a container that has held an
unknown substance or a combus-
tible material whose contents, when
heated, can produce ammable or
explosive vapors. Clean and purge
containers before applying heat.
Vent closed containers, including
castings, before preheating, weld-
ing, or cutting.
Do not touch live electrical parts. 16.
Wear dry, insulating gloves. Do not
touch electrode or conductor tong
with bare hand. Do not wear wet or
damaged gloves.
Protect yourself from electric shock. 17.
Do not use outdoors. Insulate your-
self from the work piece and ground.
Use nonammable, dry insulating
material if possible, or use dry rubber
mats, dry wood or plywood, or other
dry insulating material big enough to
cover your full area of contact with
the work or ground.
Ensure that the unit is placed on a 18.
stable location before use. If this unit
falls while plugged in, severe injury,
electric shock, or re may result.
Ground this product. This Welder 19.
requires the attachment and use of
a UL-listed, 240 volt, grounded,
3-prong, electrical Power Cord
Plug (not included). Only a quali ed
electrician should install the Power
Cord Plug. Never remove the ground-
ing prong or modify the Power Cord
Plug in any way. Do not use adapter
plugs with this product.
Avoid overexposure to fumes and 20.
gases. Always keep your head out
of the fumes. Do not breathe the
fumes. Use enough ventilation or
exhaust, or both, to keep fumes and
gases from your breathing zone and
general area.
Where ventilation is questionable,
have a qualied technician take
an air sampling to determine the
need for corrective measures. Use
mechanical ventilation to improve
air quality. If engineering controls
are not feasible, use an approved
respirator.
Follow OSHA guidelines for Permis-
sible Exposure Limits (PEL’s) for
various fumes and gases.
Follow the American Conference
of Governmental Industrial Hygien-
ists recommendations for Threshold
Limit Values (TLV’s) for fumes and
gases.
Have a recognized specialist in
Industrial Hygiene or Environmental
Services check the operation and
air quality and make recommenda-
