ArcOne Auto-Darkening Filters (Singles, Hawk, Viper) - Manual (Page 2)

- 1 -
ArcOne ® auto-darkening filters protect the user against harmful ultraviolet and infrared rays, both in the
dark and light state. No matter what shade the filter is set to, the UV/IR protection is always there.
When used properly, the filter will prevent your eyes from being burned due to optical radiation. User’s
eyes can be severely burned if welding with a damaged lens (cracked, pitted, etc.).
ANSI (American National Standards Instititue) defines all welding helmets as secondary eye
protection from optical radiation and impact. For complete safety, additional protection, such as
spectacles or goggles should be worn with welding helmets. Protective clothing and
accessories such as leather bibs attached to the welding helmet will protect the user from
spatter and optical radiation indirectly entering from areas behind the helmet.
NOTE: Not for use in overhead welding.
ACGIH (American Conference of Governmental Industrial Hygienists) has established a TLV-
TWA of 5mg/m3 for welding fumes. Welding fumes cannot be classified simply. The composi-
tion and quantity of both are dependent on the alloy being welded and the process and
electrodes used. Consult an Industrial Hygienists to ensure all your safety needs are being met.
