The Hobart 770586 lens kit is a pack of clear, replaceable cover lenses made for Hobart XVX Series auto-darkening welding helmets. Per the Amazon listing it contains five front covers and two inside (back) covers. It is a worthwhile buy if you own an XVX helmet and want to keep the main filter scratch-free; skip it if your helmet is a different series.

What the kit is for
An auto-darkening helmet has a shade cartridge that is expensive to replace. Clear cover lenses sit in front of it (and behind it) and take the spatter, grinding dust and scratches instead. When the cover gets pitted or hazy, you swap it for a fresh one in a few seconds.
This kit gives you seven pieces: five for the outside, where most of the damage happens, and two for the inside. Because they are plain clear plastic, they do not change the shade or the auto-darkening behavior of the filter itself.
How to check the Hobart 770586 fits your helmet
Cover lenses are cut to a precise shape and held by the helmet’s own frame. A near fit is not good enough, because gaps let spatter reach the filter.
- Find the model name on your helmet shell or inside the filter frame and confirm it is an XVX Series Hobart.
- Compare the model number against the compatibility line on the Amazon listing and against Hobart’s accessory pages.
- Remove your old front cover and compare the shape, corners and thickness with the new ones before you rely on them.
- Check that the front cover sits flat in its slot with no rocking, and that the inside cover clips in without bowing.
- If the shape differs at all, return it rather than modifying it.
Pros and limitations
Pros
- Cheap protection for a much costlier auto-darkening filter.
- Seven pieces means several front-cover changes before you reorder.
- Clear plastic and light weight, so it adds almost nothing to the helmet.
- Made specifically for one helmet family, so fit should be straightforward on a matching helmet.
Limitations
- Only useful if you own a matching XVX Series helmet.
- Plastic covers scratch and pit over time; they are consumables, not a lifetime part.
- Covers do not make a damaged or cracked filter safe. Replace the filter if it is damaged.
- Five fronts will not last forever if you grind a lot with the helmet down.
How to swap and care for the lens covers
- Turn the helmet off and take it out of the work area. Work on a clean, soft surface.
- Remove the old cover by the frame’s release tab or edge. Do not pry against the filter.
- Peel any protective film from the new cover, hold it by the edges and drop it into the frame.
- Clean covers with a soft cloth and mild soap and water. Avoid solvents and abrasive pads, which can cloud plastic.
- Change the front cover as soon as vision is smeared, or when you see pits or spatter marks. A dirty cover makes you tilt your head and strain.
Remember that a clear cover is not a substitute for the correct shade. If the filter is not darkening properly, stop and replace or repair it.

Frequently Asked Questions
Does the Hobart 770586 lens kit fit all Hobart helmets?
No. The listing says it is made for Hobart XVX Series helmets. Cover lenses are cut for specific frames, so confirm your helmet model and compare the shape of your current lens before relying on this kit for other Hobart or non-Hobart helmets.
How often should I replace the front cover lens?
Replace it when it is pitted, hazy or smeared enough to reduce your view, or when spatter has stuck to it. Heavy grinding or overhead work can mean a change every few sessions, while light TIG work may allow much longer between changes.
Can I clean a cover lens instead of replacing it?
Light dust can be wiped off with a soft cloth and mild soapy water. Avoid solvents and abrasive pads. Once a cover is scratched, pitted or has welded-on spatter, cleaning will not restore it, so swap it for a fresh one.
Do cover lenses change the shade of my helmet?
Clear covers do not set the shade. The auto-darkening filter does that. They only protect the filter from damage. Always check your helmet’s shade chart and settings for the process and amperage you are welding at.
Conclusion
The Hobart 770586 is a simple, low-cost way to protect an XVX Series helmet’s filter, provided you confirm the model match first. Buy it if you already own the helmet and want spare covers on the shelf.
