Welding filter OERLIKON W000010933 110x90 mm DIN 11

Welding filter OERLIKON W000010933 110x90 mm DIN 11 is a protective optical filter sized 110 x 90 mm with a DIN 11 shade rating. It is designed to be mounted in welding helmets or hand shields to reduce visible brightness and block harmful ultraviolet and infrared radiation during arc welding. The filter provides a stable viewing condition that helps maintain clarity of the weld pool while shielding the operator's eyes from excessive light and radiation.

Advantages

The optical glass with DIN 11 attenuation offers consistent darkening appropriate for medium to high intensity arc welding processes. The 110 x 90 mm format provides an ample viewing area for improved situational awareness without compromising protection. The filter's flat profile and optical coating ensure low distortion and reliable light transmission characteristics, while resisting thermal and radiative stresses typical in welding environments.

Suitable for

• Manual metal arc welding (MMA / stick welding) requiring DIN 11 protection
• MIG/MAG and TIG operations with medium to high current where DIN 11 is recommended
• Replacement in welding helmets and hand shields with a 110 x 90 mm aperture
• Workshop and field welding tasks where consistent optical performance is needed

Key specifications

• Optical shade: DIN 11
• Dimensions (approx.): 110 x 90 mm viewing area
• Material: optical filter glass with protective coatings
• Function: attenuates visible light and filters UV/IR radiation
• Form factor: flat plate suitable for helmet or shield mounting

How to use

Install the filter into a compatible welding helmet or hand shield aperture sized for 110 x 90 mm, ensuring it seats securely in the frame or retaining clips. Before welding, inspect the glass for scratches, cracks or contamination that could impair optical clarity or safety; replace if damaged. Use the DIN 11 filter for welding tasks that require medium to high light attenuation, and pair with appropriate personal protective equipment such as safety helmets, gloves and clothing. Clean the filter with a soft, lint-free cloth and a mild glass cleaner when required, avoiding abrasive materials.

Usage recommendations

Select the DIN 11 shade when process intensity and arc brightness meet recommended exposure levels for that shade; if unsure, consult welding standards or a safety officer to confirm appropriate shade selection. Store the filter in a protective sleeve when not in use to prevent scratches and contamination, and replace the filter if optical defects or coatings degradation are observed.
