The standard outside protection plate for 3M™ Speedglas™ Welding Filter Series 100 is designed to protect the filter from spark and spatter. Failure to use an outside protection plate with the filter voids the warranty if spark contaminates the glass.
Replace anytime the plate becomes deeply pitted, scratched or too dirty to clean with a soft cloth or lens paper.
