Welding Filter Lens 50 x 100 mm, Thickness 9 mm, DIN-9, No name

The Welding Filter Lens 50 x 100 mm, Thickness 9 mm, DIN-9 is a flat replacement protective lens intended for use in welding helmets and passive or auto-darkening filter assemblies. Sized 50 × 100 mm with a 9 mm thickness and DIN-9 shade, the lens provides defined attenuation of visible light and associated radiation from welding arcs to help protect the operator's eyes during manual welding tasks where this level of protection is required.

Advantages

The lens offers a compact rectangular form factor compatible with helmet windows and filter holders that accept 50 × 100 mm plates. With a 9 mm thickness it provides mechanical rigidity and stable positioning inside the carrier. The DIN-9 shade rating ensures consistent reduction of brightness for many common welding processes, and the plain, unbranded construction allows it to be used as an economical replacement part in a variety of protective assemblies.

Suitable for

• Manual arc welding tasks that require DIN-9 eye protection
• Replacement of damaged or worn filter plates in welding helmets
• Integration into passive filter stacks or protective windows in workstations
• Use in training and light industrial welding applications

Key specifications

• Nominal dimensions: 50 × 100 mm
• Material thickness: 9 mm
• Shade rating: DIN-9
• Flat, rectangular protective glass/plastic lens suitable for filter holders
• Designed for optical attenuation of welding arc radiation in the visible spectrum

How to use

Install the lens into the helmet or filter holder following the manufacturer's guidance for your specific welding hood or filter assembly. Ensure the lens sits flat and is secured to prevent movement during use. Confirm that the DIN-9 shade is appropriate for the welding process and adjust other protective layers or outer covers as required. Replace the lens if scratched, cracked or otherwise damaged to maintain effective optical protection.

Usage recommendations

Verify compatibility with your helmet or filter carrier before installation and always combine this lens with appropriate face, head and body protection as required by workplace safety rules. For processes producing higher light intensity or specific arc types, consult applicable standards to determine if a different shade level is needed.
