•
Never allow any part of the body to touch welding wire and ground or grounded work piece at the
same time.
• 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.
•
Never attempt to use this equipment at current settings or duty cycles higher than specified on
equipment labels.
•
Never use an electric arc welder to thaw frozen pipes.
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.
•
Wear ANSI approved face shield or safety glasses with side shield protection when chipping or grinding
metal parts.
•
Wear ear plugs when welding overhead to prevent spatter or slag from falling into ears.
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.
•
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 lens, flame resistant clothing,
leather welding gloves and full foot protection.
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.
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.
•
Make sure all persons in welding area are protected from heat, sparks and ultraviolet rays. Use
additional face shields and flame resistant barriers as needed.
•
Never touch work pieces until completely cooled.
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.
•
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.
•
Do not operate any electric arc welder in areas where flammable or explosive vapors may be present.
•
Take precautions to ensure flying sparks and heat do not cause flames in hidden areas, cracks, etc.
Fire hazard! Do not weld on containers or pipes that contain or have contained flammable
materials or gaseous or liquid combustibles.
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.
Do not breathe fumes produced by arc welding operation. These fumes are dangerous. If
welding area cannot be adequately ventilated, be sure to use an air-supplied respirator.
•
Keep head and face out of welding fumes.
•
Extremely toxic fumes are created when galvanized or cadmium plated metals or metals which contain
zinc, mercury or beryllium are heated.
Complete the following precautions before performing electric
arc welding operations on these metals:
a. Remove coating from base metal.
b. Make sure welding area is well ventilated.
c. Use an air-supplied respirator.
The electromagnetic field generated during arc welding may interfere with the operation of
various electrical and electronic devices such as cardiac pacemakers. Persons using such devices
should consult with their physician prior to performing any electric arc welding operations.
•
Route torch and work cables together and secure with tape when possible.
•
Never wrap arc welder cables around the body.
•
Always position torch and work leads on the same side of the body.
