Protective welding mask glass 50×100 mm, No name, E-11 filter shade

Replacement protective welding mask glass sized 50×100 mm with an E-11 filter shade. This rectangular protective lens is intended for use as an outer or inner visor in compatible welding helmets and shields. It provides a consistent attenuation level suitable for general welding, fabrication and repair operations where an E-11 filter is specified, and helps reduce exposure to sparks, spatter and radiant energy during cutting and welding tasks.

Advantages

The glass offers uniform filtering across the visible and near-infrared range corresponding to the E-11 shade, delivering predictable protection for the eyes during manual welding and cutting. Its standard 50×100 mm size fits a variety of helmet window frames designed for rectangular lenses, enabling straightforward replacement. Made for durability in typical workshop environments, the lens is simple to install and replace, ensuring continued visibility and protection when worn correctly.

Suitable for

• General arc welding (MMA, TIG, MIG/MAG) where E-11 filtering is appropriate
• Metal fabrication and light repair work
• Use as outer or inner protective glass in compatible welding helmets and hand shields
• Cutting operations producing bright arcs and hot spatter

Key specifications

• Optical filter shade: E-11
• Shape and dimensions: rectangular, 50 × 100 mm
• Intended position: outer or inner protective lens for welding masks
• Material: safety optical glass suitable for welding filters (tempered/treated for workshop use)
• Protection: reduces visible and near-infrared radiant energy consistent with the E-11 rating

How to use

Before installation, verify the helmet frame accepts a 50×100 mm rectangular lens and that E-11 is an appropriate shade for the welding process and amperage being used. Shut off any powered auto-darkening helmets and remove the existing outer and/or inner lenses following the helmet manufacturer’s instructions. Insert the replacement glass into the frame or cartridge, ensuring it sits flush and is secured according to the helmet’s retention system. Check for cracks, chips or contamination before each use and replace immediately if damaged. Use in combination with other required personal protective equipment and follow workplace safety procedures.

Usage recommendations

Use this E-11 protective glass only when the shade rating matches the welding or cutting process and current. Keep spare outer lenses available to replace scratched or contaminated glass promptly. Store unused lenses flat in a dry, dust-free place to avoid surface damage and maintain optical clarity.
