I’m not a welder, not even a mostly bad one. I have an auto darkening, probably from harbor freight and wondering about using it to look at the eclipse. What do I need to know before I do something stupid and go blind😀

I used a couple of lenses from a helmet on the last eclipse. I wanna say anything 9 or higher was GTG.
Some of the auto helmets are 8.5
This is just from memory and I'm not that smart. FYI.

I seem to remember from our eclipse a few years ago that auto darkening hoods would not respond properly to the sunlight of an eclipse, to protect your eyes.
The 'net is full of articles right now discussing the subject. A traditional hood with glass lenses is recommended with glass shades of 13 to 14.

It takes a 12 to be the safest, but a 14 is to dark.

A 10 lens and a layer or 2 of the mylar space blanket you keep in your go bag to hide from thermal optics will work too.

NASA says the only welding goggles that are safe for direct viewing of the sun are those of shade 12 or higher. But this is higher than the shade that’s typically used for most types of welding. The space agency also says that many people may still find the sun too bright with a shade 12 and some find the sun too dim with a shade 14. Meanwhile, shade 13 is even more uncommon and hard to find. American Astronomical Society (AAS) also recommends avoiding the use of adjustable or auto-darkening welding helmets or similar products to view the sun.“Many don’t go as dark as shade 13 or 14, and even those that do post a grave risk to your eyesight, either because you accidentally adjust them to an unsafe setting or because they don’t auto-darken fast enough when you look at the sun with them,” AAS says. https://www.wtsp.com/article/news/v...536-a6cb0009-43ba-4b6a-a206-68144e00ba8f

Worked for me last eclipse (2017).
I would not buy something that runs on any kind of primer given the possibility of primer shortages and even regulations. In fact, why not buy a flintlock? Really. Rocks aren't going away anytime soon.

During an eclipse there is reduces sunlight, not greater. Therefore, it wont appear "bright".
The problem with viewing an eclipse with the naked eye is the UVA and B (C is mostly filtered by stratospheric O3).
The cornea and lens filter out much of the UVB, but none of the above do much to filter UVA.
The pupil dilates in the relative darkness of the eclipse, but what isnt visible is the UVA and B
The retina/macula are therefore unprotected from damage, potentially causing minute blind spots and future macular degeneration. Will UVA and B cause the welders lens to "auto darken"?
Does a welders lens block UVA and B?
The answer to that and that only has the answer to the OP's question.
Quit giving in inch by inch then looking back to lament the mile behind ya and wonder how to preserve those few feet left in front of ya. They'll never stop until they're stopped. That's a fact.

I personally wouldn't even trust a cheap one for welding, but I trust a 3M Speedglass every day, all day. Shade 13 max, and even strobe safety lights on a fork lift and alarm strobes on machinery will trigger the lens unless I adjust it out with the sensitivity settings. The sun does infact trigger it unless the sensitivity setting is maxed. I'll be stuck inside today during that time frame and really couldn't give a damn about watching an eclipse. Betting really heavy odds that once you've seen one you've probably seen 'em all.

If the sky is clear I’ll view it with my iPad. Seen one before. Mostly I’m interested in how dark it gets down here.
