This pack contains ten standard replacement outside cover lenses (part number 776000) designed for the 3M Speedglas Welding Helmet Series 100. These cover lenses protect the auto-darkening lens from sparks, spatter, and other welding debris, ensuring clear visibility and prolonging the life of the helmet's lens.

Outside cover plates are essential for maintaining the performance and safety of your Speedglas 100 welding helmet. It is recommended to replace these cover lenses once or twice a week depending on the frequency and intensity of use. This helps maintain optimal lens clarity and protection during welding operations.

The cover lenses measure 145 x 86 mm and are also available in alternative versions such as hard-coated (part number 777000) or high-heat resistant (part number 777070) to suit different working environments and durability requirements.
