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 fitted with a proper shade of
filter (see ANSI Z49.1 listed in Safety Standards) 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 flash and glare; warn others not to watch the arc.
4. Wear protective clothing made from durable,
flame-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 breathe 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.

* As a rule of thumb, start with a shade that is too dark to see the weld zone. Then go to a lighter shade which gives sufficient
view of the weld zone without going below the minimum. In oxyfuel gas welding, cutting, or brazing where the torch and/or
the flux produces a high yellow light, it is desirable to use a filter lens that absorbs the yellow or sodium line of the visible
light spectrum.
