HELMET INFORMATION
This Auto-Darkening Welding Helmet will automatically change from a light state (shade 3.5) to a dark state (Shade
9-13) when arc welding starts. The filter automatically returns to a light state when the arc stops. Shade control
adjustments can be made while welding. Match your welding application to the shade indicated on the shade chart.
(See Page 4). Do not use or open the auto-darkening filter if damaged by shock, vibration or pressure. The functionality
of the filter can be checked verifying its darkening when exposed to intense light (direct sun or welding flash). Keep
the sensors and solar cell clean. Clean the filter cartridge using a soapy water solution and soft cloth which should be
damp but not saturated. This Auto-Darkening Welding Helmet is designed for use with Stick Welding (SMAW); TIG
DC∾ TIG Pulse DC∾ MIG/MAG/CO2/Pulse; Plasma Arc Cutting (PAC); Plasma Arc Welding (PAW); Air Carbon
Arc Cutting (CAC-A); Grinding. The cartridge provides protection from harmful UV and IR radiation, in both dark and
light states. The cartridge contains two sensors to detect the light from the welding arc, resulting in the lens darkening
to a selected welding shade. Do not use solvents or abrasive cleaning detergent. . If cover lens is spattered or covered
with dirt, it should be replaced immediately. Do not use the helmet without inside and outside cover lenses properly
installed. We recommend a use of the helmet / ADF / safety oculars for a period of 3 years. The duration of use
depends on various factors such as use, cleaning storage and maintenance. Frequently inspections and replacement
if it is damaged are recommended.
