Abstract
A welding shield includes a frusto-conical metal shield member, open at top and bottom, and including a wall opening for welding gun access. A lens is removably mounted in the top of the shield member, and a horizontal metal screen is removably mounted within the shield member between wall opening and lens. A circumferential base around the bottom is of a flexible and nonflammable material for effective closure around a weld work area. The work area is viewable, magnified, by the lens. The welding shield is lightweight for easy movement and placement by one available hand of the user.
