Protective welding helmet glass pane 80×100 mm No name E-12 (MAS SZ 12/80)

Replacement protective glass pane sized 80×100 mm designed for welding helmets, model E-12 (MAS SZ 12/80). This clear cover fits standard 80×100 mm front lens frames and protects the helmet's optical assembly from sparks, spatter and debris encountered during manual welding and workshop tasks. The pane is intended as a wear part to maintain visibility and extend the service life of the welding lens.

Advantages

The protective pane provides a transparent barrier that preserves the underlying filter or lens from physical damage and contamination without altering optical clarity. It is manufactured to match the common 80×100 mm size, enabling straightforward replacement in compatible helmets. The simple, flat design ensures uniform light transmission and minimal distortion while reducing the need for frequent deep cleanings or replacements of the main filter.

Suitable for

• Manual welding tasks such as MMA, TIG and MIG/MAG where a standard front lens is used
• Workshop and fabrication environments with regular exposure to sparks and metal spatter
• Routine maintenance and replacement of worn or scratched protective covers on welding helmets

Key specifications

• Dimensions: 80 × 100 mm (clear flat protective pane)
• Material: transparent protective glass suitable for front-lens coverage
• Shape: rectangular, flat profile for standard mount frames
• Function: protects optical filter from sparks, spatter, dust and mechanical abrasion

How to use

Turn off and remove any active electronic filter from the helmet if applicable, then detach the existing front protective cover from the lens frame according to the helmet manufacturer’s instructions. Clean the lens frame area of loose debris before placing the replacement pane. Align the 80×100 mm pane within the frame and secure it using the helmet’s retaining mechanism. Inspect the pane for correct seating and optical clarity before resuming work.

Usage recommendations

Regularly check the protective pane for scratches, cracks or heavy contamination and replace it when visibility is reduced. Use appropriate hand protection when handling hot or recently used helmets, and store spare panes in a clean, dry place to avoid surface damage prior to installation.
