3M has introduced its WS series of welding shields for protection against eye injuries caused by arc welding, including ultraviolet and infrared radiation.
The WS-320/37154 for SMAW, GMAW/MAG, and GTAW features an auto-darkening filter and allows the user to select from three variable dark-state shade levels of 10, 11, and 12. The filter is shade 4 in the light state. Two user-selectable sensitivity levels help provide arc detection in differing work and environmental conditions.
The WS-110/37155 features a standard shade-10 glass filter plate.
