The Speedglas 9100 high temperature outside protection plate is formulated from an engineered resin to resist higher heat applications. This is recommended for use in high amperage welding or conditions where long weld beads may generate radiant heat.
3M™ Speedglas™ Outside Protection Plates are a replacement part designed to be used when the original has been damaged or worn out. Help protect your welding filter from sparks and spatter by ensuring that your Outside Protection Plate is functioning properly.
