Only operate these ADFs at temperatures between 23°F (–5°C) and 131°F (+55°C). If used outside of this
range, the filter may not perform as designed and
may result in permanent eye injury and vision loss
.
GENERAL SAFETY INFORMATION
This product contains no components made from natural rubber latex.
Intended Use
The 3M™ Welding Shield Assemblies WS Series are designed to help protect the wearer’s eyes from harmful
radiation including visible light, ultra-violet radiation (UV) and infrared radiation (IR) resulting from certain
arc-welding processes when used in accordance with these
User Instructions
. Two sensors on the front of the
ADF WS Series react independently at the moment the welding arc is struck and cause the filter to darken. The
ADF switches back to the light shade (shade 4) as soon as the welding arc has stopped. Two lithium batteries are
used as the power source. The ADF will switch off automatically approximately
60 minutes after the last arc is
detected. Protection from ultra-violet radiation (UV) and infrared radiation (IR) is continuous, whether the ADF is
in the light or the dark state. In the event of battery or electronic failure, the welder remains protected against UV
and IR radiation according to the darkest shade (shade 12).
3M™ ADFs allows the welder to view their work clearly and safely during set-up, during the weld and after
without interruption and without the burden or delay of manually lifting the shield or filter. 3M ADFs allow
manual arc welding to be performed more quickly and accurately in comparison to traditional passive welding
filter plates.
Important Use Limitations:
•
These products do not provide any protection from respiratory hazards that may result from welding processes
or from other sources. 3M™ Welding Shields WS Series may be worn in conjunction with certain respirator
models. For more information about respiratory protection for welders, contact 3M Technical Service at
1-800-243-4630. In Canada, call Technical Service at 1-800-267-4414.
•
The ADF WS-020/37156 is not suitable for gas welding (e.g., oxyacetylene), low-amperage TIG welding
(below 20 amps), laser welding, or welding processes that require shade 13 or higher filters. Use of this
product for these applications
may result in permanent eye injury and vision loss
.
•
Only operate the ADF at temperatures between 23°F (–5°C) and 131°F (+55°C). If used outside of this range,
the filter may not perform as designed and
may result in permanent eye injury and vision loss
.
