Welding filter OERLIKON 110x90 mm DIN-9 (90x110x9) for protective helmet lenses

OERLIKON welding filter 110x90 mm DIN-9 (model 90x110x9) is a rectangular protective lens insert designed for welding helmets and face shields. It provides DIN-9 optical density suitable for medium to high-intensity welding arcs and fits holders sized 110 x 90 mm. The filter reduces visible light and blocks harmful ultraviolet and infrared radiation, helping to protect the eyes from glare, spatter and arc radiation during manual and semi-automatic welding tasks.

Advantages

The OERLIKON DIN-9 filter offers standardized optical density to ensure consistent protection under medium to high arc currents. Its rectangular 110 x 90 mm format is compatible with a wide range of helmet holders and passive face shields, allowing straightforward replacement of worn or damaged lenses. The glass (or optical-grade) construction provides stable optical characteristics and scratch resistance appropriate for workshop environments. The filter maintains color balance and visual clarity necessary for positioning and monitoring welds while reducing exposure to UV and IR emissions.

Suitable for

• Manual arc welding (MMA / stick welding) with medium to high currents
• MIG/MAG and TIG welding where a passive DIN-9 shade is specified
• Use as a replacement protective lens in compatible welding helmets and face shields sized 110 x 90 mm
• Workshops, maintenance departments, and fabrication shops performing short to extended welding operations

Key specifications

• Optical density: DIN-9 (passive shade)
• Nominal dimensions: 110 x 90 mm (rectangular)
• Thickness: approximately 9 mm nominal optic thickness
• Material: optical-grade glass or equivalent protective lens material
• Protects against: ultraviolet (UV) and infrared (IR) radiation and intense visible light from welding arcs

How to use

Install the filter into a compatible helmet or face shield holder sized for a 110 x 90 mm insert, ensuring the lens seats evenly and the retaining clips or frame secure it without stress. Inspect the filter before each use for cracks, deep scratches or contamination; replace the filter if damaged or if optical clarity is compromised. Use the DIN-9 shade when welding processes produce medium to high-intensity arcs; verify that local safety procedures and workplace risk assessments specify DIN-9 for the intended current and process.

Usage recommendations

Store the filter in a protective sleeve or box to avoid surface damage when not in use. Clean with a soft, lint-free cloth and approved lens cleaner; avoid abrasive materials and strong solvents. Always combine the filter with appropriate helmet, face and body protection and follow relevant safety standards and workplace guidelines regarding welding eye protection.
