Welding Helmet Glass Replacement 80x100 mm E-11, MAS SZ 11/80

Replacement protective glass sized 80 × 100 mm, model E-11 (MAS SZ 11/80), designed as a cover lens for welding helmets. This replacement glass fits helmets and visor assemblies that accept an 80×100 mm viewing window and is intended to protect the underlying auto-darkening filter or fixed shade from spatter, scratches and surface contamination while maintaining a clear viewing area for welding and cutting tasks.

Advantages

The replacement glass is made to the E-11 optical class and dimensions 80×100 mm to provide consistent fit and reliable surface protection. It preserves visibility through the helmet by protecting the primary filter from damage, reducing the need for more frequent and costly replacements of the main lens. The flat, thin profile makes installation straightforward and it does not interfere with common helmet mounting frames that accept standard cover lenses.

Suitable for

• Welding helmets and face shields that require an 80×100 mm cover lens
• Protecting auto-darkening or fixed filter windows during arc welding, MIG/MAG, TIG and plasma cutting
• Workshops and job sites where spatter and sparks frequently impact the helmet window
• Routine maintenance kits for professional welders and hobbyists

When it may not be suitable

This replacement glass is intended as a cover/outer lens and not as the primary optical filter for eye protection. It does not change the shade or switching characteristics of an auto-darkening lens and should not be used alone in place of a certified welding filter. It may not fit helmets that use non-standard window sizes, curved shields, or proprietary mounting systems that deviate from the 80×100 mm flat cover format.

Key specifications

• Lens type: flat cover/outer protective glass
• Optical class: E-11 (as specified for the cover lens model)
• Size: 80 × 100 mm
• Function: protects inner filter from spatter, scratches and contamination
• Material characteristics: thin, rigid protective glass suitable for helmet cover use

How to use

Remove the helmet’s outer retaining frame or clips according to the helmet manufacturer’s instructions. Clean the mounting area to remove dust and debris, then position the 80×100 mm replacement glass into the frame ensuring correct orientation and a flush fit. Secure the retaining frame or clips and check that the cover lens sits flat without gaps. Inspect the cover glass before each use and replace it when pitted, cracked or heavily scratched to maintain a clear view and effective protection of the inner filter.

What to consider before purchase

• Confirm your helmet accepts an 80×100 mm flat cover lens and uses the E-11 style insert
• Verify this cover glass is compatible with your helmet’s mounting frame and clip system
• Understand that this is an outer protective glass, not a replacement for the primary certified welding filter
• Check the quantity you need and whether you should keep spares for frequent use conditions

Usage recommendations

Use the cover glass as a sacrificial protective layer and replace it at the first sign of pitting or severe scratching. Regularly clean with a soft, lint-free cloth and non-abrasive cleaner to maintain visibility. Keep spare cover lenses available on-site to ensure continuous protection of the main filter during prolonged or heavy-duty welding operations.
