Powerweld Horizontal Single Auto-Darkening Filter for Welding, 2 x 4″, (Shade 11): Product Breakdown

“>

The Powerweld Horizontal Single Auto-Darkening Filter for Welding, 2 x 4″, (Shade 11) is a helmet-support component for users who need a compact auto-darkening lens format and are already working within a 2 x 4 in. lens system. For buyers and maintenance teams, the main job is not just to read the advertised values. It is to verify fit, viewing area, cover plate requirements, and how the lens will be used in the helmet assembly.

Key Takeaways

• Format is 2 x 4 in. and the listed view size is 1.3 in. x 3.5 in. (34 mm x 88 mm).
• Listed speed is 0.2 ms, light state shade is 3, and dark state shade is listed as Unknown (Verify) in the source data.
• Thickness is listed as 1/5 in. (5.0 mm) and weight is 45 g.
• It must be used with a protective cover plate.
• Do not assume compatibility with any helmet shell, cartridge holder, or cover plate without measuring and checking the manufacturer’s requirements.

What this lens is for

This is an auto-darkening filter intended for welding helmet support use. In practical terms, that means it belongs in the front-window stack of a compatible helmet, where it can switch from a light state to a dark state during arc exposure. For the maintenance buyer, the critical issue is not only the shade number. It is whether the lens dimensions, thickness, and mounting style match the helmet and whether the front cover plate package is correct.

Inspect before you install

Use these checks before the lens goes into service:

• Check the lens opening. Measure the helmet window and verify that a 2 x 4 in. filter is the correct format.
• Inspect the cover plate requirement. The source states the filter must use a protective cover plate. Verify the cover plate size, thickness, and orientation before installation.
• Verify the view area. The listed viewing area is 1.3 in. x 3.5 in. Confirm whether that matches the operator’s field-of-view needs and the helmet frame.
• Check thickness. The source lists 5.0 mm thickness. Verify the cartridge pocket or front assembly has clearance.
• Inspect the lens face and edges. Look for scratches, cracked housing, or warping before use.
• Verify light state behavior. The source lists light state shade 3. Confirm the lens transitions correctly in a safe test setup before welding.

Troubleshooting and support checks

If the lens is not behaving as expected, work through the problem in order:

• Check the helmet fit. If the lens shifts or gaps at the frame, verify the helmet opening and retaining hardware.
• Inspect the cover plate. A missing or incorrect protective cover plate can expose the filter and reduce service life. Replace with the correct plate if required.
• Verify orientation. Horizontal single filters are directional in practice. Confirm the lens is installed in the intended orientation and seated evenly.
• Check the arc response in a controlled setting. If the lens is not darkening or appears inconsistent, verify that the problem is not from installation, damage, or contaminated front surfaces.
• Inspect for contamination. Grinding dust, spatter, and smoke film on the cover plate can affect visibility and perceived response.
