Inside Lens Cover for VIKING 3350 Series

The Lincoln Electric KP3044-1 is a replacement inside lens cover designed for VIKING 3350 series welding helmets. It protects the auto-darkening filter from spatter and debris while maintaining optical clarity for the operator. The clear plate measures 4-1/2" x 5-1/4" with a 0.04 in thickness and a filter shade 3 rating. Welders using compatible VIKING headgear rely on this cover to reduce eye strain during extended jobs.

Snap-in installation with exact fit required

The cover installs by snapping into the helmet's internal lens retainer; no tools are needed. Alignment tabs must match the helmet's slots exactly or the cover will not seat flush, allowing smoke to reach the filter. Users sometimes order this part for other VIKING models where the plate dimensions differ, resulting in a loose fit. Buyers who need an outside cover or a different shade rating should verify the correct part number before purchasing.

Questions about this item

How do I confirm the KP3044-1 inside lens cover is fitted correctly on my 3350 series helmet?

After installation, verify the clear 0.04 in thick cover sits flat behind the front plate, matching the 4-1/2 x 5-1/4 in dimensions, and that visibility through the shade 3 filter is unobstructed.

What comes in the box with the KP3044-1 and what must I buy separately for my 3350 series helmet?

The package contains one clear inside lens cover sized 4-1/2 x 5-1/4 in with 0.04 in thickness and shade 3 filtration; front outside covers, headgear parts and the helmet shell itself are sold separately.
