MSA's thermal plastic welding shields are designed to protect a worker's eyes and face from infrared burns, flying sparks, hot metal spatter and chips encountered in welding operations. The nylon welding shields come in a variety of styles, available with plate holders measuring either 2"x4-1/4" or 4-1/2"x5-1/4". When protection from overhead hazards is required, MSA's welding shields may be attached to protective headwear with various accessories from MSA.
