ARC RAYS can burn eyes and skin.
Arc rays from the welding process produce intense visible and invisible (ultraviolet
and infrared) rays that can burn eyes and skin. Sparks fly off from the weld.
•
Wear a welding helmet fitted with a proper shade of filter to protect your
face and eyes when welding or watching (see ANSI Z49.1 and Z87.1 listed
in Safety Standards). Refer to Lens Shade Selection on page 6.
•
Wear approved safety glasses with side shields under your helmet.
•
Use protective screens or barriers to protect others from flash, glare,
and sparks; warn others not to watch the arc.
•
Wear protective clothing made from durable, flame-resistant material
(leather, heavy cotton, and wool) and foot protection.
•
Before welding, adjust the auto-darkening lens sensitivity setting to meet the
application.
•
Stop welding immediately if the auto-darkening lens does not darken when the
arc is struck.
•
See the Owner’s Manual for more information.
