Protective welding mask glass 50x100 mm, shade E-9, No name (MAS SZK E-9)

Replacement protective welding mask glass sized 50×100 mm with a fixed shade rating E-9. This glass is designed for use in compatible welding helmets and face shields to reduce arc brightness and protect the eyes from spatter and infrared/visible radiation during medium-intensity welding operations. It provides a stable optical filter that supports clear forward vision while maintaining required protection for MIG/MAG, TIG and MMA welding tasks where an E-9 shade is appropriate.

Advantages

The glass offers consistent attenuation of bright welding arcs at a fixed E-9 shade, ensuring uniform protection without the complexity of auto-darkening systems. Its compact 50×100 mm format fits standard viewing windows in many helmets and shields, allowing straightforward replacement. Constructed for optical clarity, the filter minimizes distortion and supports accurate work positioning while guarding against spatter and glare.

Suitable for

• MIG/MAG welding with medium-intensity arcs
• TIG welding where a fixed E-9 shade is acceptable
• MMA/stick welding for general maintenance and fabrication
• Workshop and on-site welding where a simple passive filter is preferred

Key specifications

• Filter type: passive fixed-shade protective glass
• Shade level: E-9 (fixed)
• Dimensions: 50 × 100 mm viewing area
• Optical function: reduces visible and infrared radiation from welding arc
• Intended use: compatible with helmets and face shields that accept a 50×100 mm insert

How to use

Verify that your welding helmet or face shield supports a 50×100 mm passive filter and that an E-9 shade matches your welding process and current. Remove the damaged or worn insert according to the helmet manufacturer's instructions and install the replacement glass so it sits securely in the housing without gaps or movement. Inspect the glass for cracks, scratches or contamination before each use and replace it if visibility or protection is compromised. Use the filter only in dry, undamaged condition and combine it with appropriate personal protective equipment, such as a welding helmet, gloves and protective clothing.

Usage recommendations

Choose this fixed E-9 protective glass for medium-intensity welding tasks when a simple, reliable passive filter is sufficient. For varying arc intensities or automated darkening needs, consider using an auto-darkening solution matched to your application. Always follow workplace safety rules and replace the glass if its surface is damaged or visibility is reduced.
