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.\u003c\/p\u003e\n\u003cp\u003eThis 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.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eInside-mounted cover lens protects the ADF cartridge from spatter and contamination\u003c\/li\u003e\n  \u003cli\u003eCompact profile at 6.69 x 2.6 x 0.2 inches fits standard welding helmet lens bays\u003c\/li\u003e\n  \u003cli\u003eConsumable replacement part suitable for routine helmet maintenance\u003c\/li\u003e\n  \u003cli\u003ePack format supports efficient inventory stocking for shops and field crews\u003c\/li\u003e\n  \u003cli\u003eLightweight construction at approximately 0.07 pounds per pack\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement inside cover lens for welding helmets that accept a lens measuring 6.69 x 2.6 inches in the inside lens position.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInside cover lens replacement is performed by welders and helmet technicians as part of standard PPE maintenance.
