Red Fierce Auto Darkening Welding Helmet Variable Shade 7-13 with Grind Mode

The knob on the left side on the outside of the helmet. You need to put batteries in it also. Hope this helpful.

I have this helmet and just looked here for the specs to check the answer to this question for myself. According to NASA, yes, you need a minimum of 12 and 13 is optimal as 14 is too dim for some people. So, with all due respect to Lincoln's answer, yes, this helmet is able to view the eclipse as long as the specs are accurate but your eyes are on the line so you are taking your own chances. Here is a quote from NASA - Viewing with Protection -- Experts suggests that one widely available filter for safe solar viewing is welders glass of sufficiently high number. The only ones that are safe for direct viewing of the Sun with your eyes are those of Shade 12 or higher. These are much darker than the filters used for most kinds of welding. If you have an old welder's helmet around the house and are thinking of using it to view the Sun, make sure you know the filter's shade number. If it's less than 12 (and it probably is), don't even think about using it to look at the Sun. Many people find the Sun too bright even in a Shade 12 filter, and some find the Sun too dim in a Shade 14 filter — but Shade 13 filters are uncommon and can be hard to find. The AAS Reputable Vendors of Solar Filters & Viewers page (link is external) doesn't list any suppliers of welder's filters, only suppliers of special-purpose filters made for viewing the Sun.To find out more about eyewear and handheld viewers go to https://eclipse.aas.org/eye-safety/eyewear-viewers

The newer helmet does have this feature. The selection switch on the left temple has a marked position for grind mode..
