Misc. Lenses FAQs

Answers to common questions about replacement cover lenses and protective plates for welding helmets and auto-darkening filters.

What is the difference between an inner and an outer cover lens?

The outer (front) cover lens sits in front of the welding filter and takes the sparks, spatter and grinding debris so the filter behind it does not have to. The inner cover lens sits on the wearer's side of the filter and is replaced if it becomes damaged, for example cracked or pitted.

Both are clear, replaceable parts. Many helmets use both, some use only an outer lens, so check the manual for which positions your helmet has.

Can I clean a cover lens, or should I just replace it?

Light dust and smears can usually be wiped off gently with a clean, lint-free tissue or cloth. Helmet manuals advise against strong cleaning solutions, and recommend keeping the filter's sensors and solar cells clean in the same way.

Do not scrub at spatter that has fused to the surface, because that scratches the lens. Once the surface is pitted or scratched, cleaning will not restore it and the lens should be replaced. Follow the cleaning advice in your helmet's manual.

Why does the view go dim or hazy even with a good filter?

A dirty or damaged cover lens is one of the commonest causes. Helmet manuals list a dirty or damaged front cover lens in their troubleshooting section, with the fix being to change the lens. Replace it with a fresh one and the view often improves straight away.

Other causes can include the shade setting, a dirty filter or sensors, or a low battery on an auto-darkening unit. Check the lens first because it is quick and simple. If the view is still poor, refer to the manual or ask the maker, and do not carry on welding with a view you cannot see clearly.

How do I know which cover lens fits my helmet?

Cover lenses are usually made for a particular helmet or filter series, and makers list which helmets each lens suits, so a lens that looks close can still sit loosely or leave a gap. Start with the helmet maker's manual or parts list, which names the correct lens for each position, and check the helmet or filter label for the model.

If you cannot identify it, measure the old lens (length and width, and whether it is rectangular or round) and note the shape of any cut-outs or notches. Our team can help you match it if you are unsure.
