Replacement Cover Lens Kit

This Lincoln Electric KH778 kit supplies two polycarbonate cover lenses for compatible auto-darkening welding helmets. The clear lenses shield the operator from harmful UV and IR radiation during welding tasks. They are designed as direct replacements for worn or damaged originals. The kit fits Lincoln Electric helmet series including models K2933-1 and K3063-1.

Compatibility Check

Verify that your helmet belongs to the Lincoln Electric series listed and matches the plate dimensions of 3 27/32 in length by 1 7/8 in width with a 0.25 in thickness. These lenses provide no magnification, so users requiring magnified vision will need a different solution. Confirm the inside and outside lens positions before fitting. The product carries California Proposition 65 warnings for cancer and reproductive harm.

Durability and Safety

Polycarbonate construction resists impact and heat encountered in normal welding use. Clear material maintains optical clarity while blocking UV and IR radiation. Regular inspection and timely replacement preserve protective performance. No power draw, noise or thermal management considerations apply to these passive lens components.
