Helmet Lenses & Accessories

Replacement welding helmet lenses - clear cover plates and passive dark filter shades in both standard sizes, 2" x 4.25" and 4.5" x 5.25".

The cover lens is the consumable - the filter is not

A correctly built helmet has a clear cover plate in front of the filter and usually a second clear lens behind it. Those clear plates take the spatter, the pitting and the scratches. The filter behind them should last years.

If you are replacing filters because they are damaged, the cover plates were missing or were left in too long. Keep a pack of clear lenses on the shelf and change them the moment the view degrades - a scratched cover plate is a welder squinting, and squinting is bad welds and headaches.

Two sizes, and they are not interchangeable

• 2" x 4.25" - the traditional filter plate size, used in passive helmets and flip-front hoods.
• 4.5" x 5.25" - the larger viewing area, used in wide-view passive helmets.

Measure the lens you are replacing, or the helmet's retaining frame, before ordering. Cutting a lens to fit destroys its edge and its rating.

Shade selection is not personal preference

Shade number is set by process and amperage, not by comfort. Too light and you take arc-eye and long-term retinal exposure; too dark and you cannot see the puddle, so you lean in and weld badly.

As a working guide: shade 10 covers most stick and MIG work at moderate amperage, lighter shades suit low-amperage TIG and gas work, and higher amperage needs 11 to 13. If you cannot see the leading edge of the puddle, go one shade lighter and add light on the work rather than staying blind.

Polycarbonate stops UV even when it looks clear

A clear polycarbonate cover plate is not just a physical shield - polycarbonate blocks UV across the welding range. That is why a helmet is never run without one, and why a cracked cover plate is replaced rather than taped.

Check the rating, not just the fit

Lenses carry an ANSI Z87.1 marking. An unmarked lens from an unknown source may pass light it should be stopping, and there is no way to tell by eye. The saving is a few dollars and the exposure is your eyesight.
