I always use a big glass hood for auto dark lenses...so could not tell you the best single for your pancake. I use the old school auto lens in my stick hood, a flip up.
Not many major brands make regular size single auto darks anymore. Arc one has the widest selection of them far as I know, there full size lenses are very light so I expect the singles to be the same. In the ones I have owned I got rid of the cheap ones quickly as they shaded unevenly (like Shad was talking about) and it bugged me a lot. I had to spend some bucks on the higher end models before I found some that were as consistent as a good glass lens.
http://www.arc1weldsafe.com/auto-darkening-filters.html"I've never worn glasses, so have not had UV protection before." Not picking on you Tyrone, not trying to be a smart alack either, just wanted to clarify something. Every time you use a welding lens you have UV protection. The light you actually can see from a welding arc is not what burns your eyes, it is the high intensity
invisible Ultra-Violet light that smokes them and causes real damage. Intense bright light in the visible spectrum causes irritation and temporary overloading of the light receptors in your eyeball, it can cause damage but because you CAN see it people have a natural tendency to look away. Otherwise strobe lights and such would have been outlawed back in the days of disco when all the John Travolta wannabes started walking into light poles and traffic. A filter shade number is just to make it more comfortable to look at the arc, just like sunglasses make it more comfortable to see on a sunny day. All welding lenses filter UV radiation that is actually what is protecting your eyes. A shade 9 filters UV just as much as a shade 13, you just don't realize it because you cannot see the UV.
