To permit one to simultaneously observe and record details of a welding operation, a conventional welder's mask 10 is al-tered by (1) removing a narrow 5/32" strip 12 from the lower peripheral area of the filter 14, (2) reducing the total thickness of the filter/cover glass combination to improve the visual angle, and (3) adding a 2" radial cutout at the neck portion 16 of the mask.
