The Lincoln Viking 3350 lens kit is a bundle of replacement cover lenses: the listing describes 10 outside lenses and 10 inside lenses made for Viking 3350 series welding helmets. If your current covers are pitted or scratched, this is a cheap way to get a clear view again without replacing the whole filter. The 3350 series lens kit replaces worn lenses on compatible welding helmets.
Quick Answer
- What you get (per the listing): 10 outside cover lenses and 10 inside cover lenses for the Viking 3350 series.
- Best for: owners of a Lincoln Viking 3350 helmet who want a multi-month supply of spares.
- Skip if: your helmet is a different model, or you also need a new shade filter, since these are clear covers only.

What Cover Lenses Do and Do Not Do
The outside cover lens takes the spatter and grinding dust so the filter behind it stays clean. The inside cover lens keeps dust and sweat off the back of the filter. Neither one is rated to replace the shade filter, and neither adds eye protection from the arc.
A cheap cover lens is the right place to take wear. Swapping it costs far less than a scratched filter.
How to Replace Viking 3350 Cover Lenses
- Set the helmet on a clean bench and remove the headgear if it blocks the lens frame.
- Open the lens frame the way your manual describes and lift out the old outside cover lens.
- Peel the film off the new lens if it has one, and avoid touching the clear face.
- Seat the new lens flat and make sure it sits fully inside the retaining tabs.
- Repeat for the inside cover lens, then close the frame and check there are no gaps for light or spatter.
- Look through the helmet at a light source to confirm there are no smudges or bubbles.
If anything in this process differs from the instruction sheet that comes with your helmet, follow the Lincoln manual.
Pros and Limitations
Pros
- Large pack size for the price class, so you can change lenses often.
- Matches the Lincoln part numbers used on the Viking 3350 series.
- Quick, tool-free change on most helmets of this type.
Limitations
- Cover lenses only. They do not replace the shade filter.
- Fit is specific to the 3350 series.
- Clarity and scratch resistance are things to check on the listing and in buyer feedback, since we have not tested the kit.
Lens Care Tips
- Check the outside lens before each session and swap it as soon as you cannot see the puddle clearly.
- Store spare lenses flat in their bag so they stay free of dust and scratches.
- Clean with a soft cloth only. No solvents.
- Inspect the filter lens too. A cracked or pitted filter needs replacement, not just new covers.

Frequently Asked Questions
Which Lincoln helmets does this lens kit fit?
The kit is sold for the Lincoln Viking 3350 series. The part numbers it references, KP2898-1 (outside) and KP3044-1 (inside), are Lincoln part numbers for the 3350 series cover lenses. Check your helmet model against the listing before you order.
How often should I replace the cover lenses?
Replace them when they are pitted by spatter, scratched, cracked, or hard to see through, not on a fixed calendar. Heavy grinding or overhead work may use them up in days, while light shop use can make them last much longer.
Do cover lenses protect my eyes from arc light?
No. Cover lenses only shield the shade filter from spatter and scratches. Eye protection from arc UV and IR comes from the filter lens, so never weld without it in place.
Can I use these lenses on another brand of helmet?
Not unless the lens shape and size match your helmet. These are cut for the Viking 3350 series, so measure and compare before you try them in anything else.
How do I clean a cover lens?
Wipe loose dust with a soft cloth or lens tissue. Avoid solvents and abrasives, and replace a lens that stays smeared or scratched, since it hurts your view of the puddle.
