摘要：

A welding helmet 10 that has a face shield 12 that has a native width NW and that has a lens 14 disposed in the face shield 12. A spreader bar 30 can expand the face shield 12 from its native width NW to an increased width IW to allow the welding shield 10 to easily accommodate earmuffs 16 worn by the welder.
