Best Welds 901-A-428 Inside Cover Lens

Product Description

The BEST WELDS 901-A-428 is an inside cover lens designed to protect the auto-darkening filter (ADF) cartridge in a welding helmet from spatter, dust, and debris generated during the welding process. Positioned on the inner face of the helmet lens assembly, this cover lens acts as a sacrificial barrier that extends the service life of the more expensive ADF unit. It measures 6.69 inches in length, 2.6 inches in width, and 0.2 inches in height, fitting standard helmet lens openings of that profile. Replacement is a routine part of helmet maintenance performed by welders and fabricators across all welding disciplines.

This inside cover lens is suited for use in MIG, TIG, stick, and flux-core welding applications where spatter and fume exposure are constant. It is a consumable component typically kept on hand in fabrication shops, maintenance departments, and field welding kits. The 901-A-428 is sold in a pack configuration, making it practical for volume stocking by welding professionals who service helmets regularly or outfit multiple crew members.
