EXCEL ARC 6045 SAFETY INSTRUCTIONS
Manual 0-5213 1-2 August 26, 2011
WARNING
ARC RAYS can burn eyes and skin; NOISE can
damage hearing.
Arc rays from the welding process produce
intense heat and strong ultraviolet rays that
can burn eyes and skin. Noise from some
processes can damage hearing.
1. Wear a welding helmet fi tted with a proper shade of
fi lter (See ANSI Z49.1 in “1.02 Principal Safety
Standards” on page 1-5) to protect your face and
eyes when welding or watching.
2. Wear approved safety glasses. Side shields
recommended.
3. Use protective screens or barriers to protect others
from fl ash and glare; warn others not to watch the arc.
4. Wear protective clothing made from durable,
fl ame-resistant material (wool and leather) and foot
protection.
5. Use approved ear plugs or ear muffs if noise level is
high.
WARNING
FUMES AND GASES can be hazardous to your
health.
Welding produces fumes and gases. Breathing
these fumes and gases can be hazardous to
your health.
1. Keep your head out of the fumes. Do not breath the
fumes.
2. If inside, ventilate the area and/or use exhaust at the
arc to remove welding fumes and gases.
3. If ventilation is poor, use an approved air-supplied
respirator.
4. Read the Material Safety Data Sheets (MSDSs) and the
manufacturer’s instruction for metals, consumables,
coatings, and cleaners.
5. Work in a confi ned space only if it is well ventilated,
or while wearing an air-supplied respirator. Shielding
gases used for welding can displace air causing injury
or death. Be sure the breathing air is safe.
6. Do not weld in locations near degreasing, cleaning, or
spraying operations. The heat and rays of the arc can
react with vapors to form highly toxic and irritating
gases.
