blue lens for arc welding

I have a blue lens with gold coating, shade 10. Marked "T 10 H" on the gold side.I used it for a few days of tig welding, ~4hrs actual booth time a day. View is crystal clear, colors are very easy on my eyes. Thing makes NR232 look almost like a white led.After some thinking I started reading and found what seems like conflicting info.Some say blue lenses are strictly for O/A welding aluminum and some say they don't block the UV of an arc.I see the old American Optical blue lenses are highly desired for welding with no mention in those threads of O/A al use only.I asked the senior instructor at my welding school today and he said as long as its shade 10+ that's all that matters.I didn't get sore using it but I'm still worried about long term damage.Can somebody clarify this for me? Are the cobalt lenses for O/A different from the AO weld cool lenses? I don't think my blue lens is an AO but how do I know if this thing is safe for long term daily welding?
Reply:I dunno about the lens itself, but it seems that if you have a UV filtering clear lens in front of it, and you're wearing UV protective safety glasses underneath your helmet, you shouldn't have a whole lot to worry about.You didn't build that.'85 Miller AEAD-200LE
Reply:I continue using the AO "Mirror Lens" or the Cobalt Blue as it's also known. I wouldn't use anything else. No need to go to an auto darkening hood if you have a Mirror Lens. Take care of it and it will last many years.Thanks,HoboLincoln SA200's... at least 15 - 20. They come and go. Growing partial to the "Short Hoods" in my old age.

Reply:Your lense is a shade 10.  A shade 5 is used for oxy/fuel.  Any shade, 9 through 12 is used for electric arc procedures, based on circumstance and preference.  Also worth noting, the use of a non-mirrored lens does not dictate the need for an auto.Last edited by mb_welder; 09-16-2012 at 04:20 AM.

Reply:Im kinda concerned myself. My eyes are getting bad and today I used an aqua blue shade #9 welding 1/8 7018 with a cheater lens. Not to sure that was a good idea.
Reply:I have used (until it got 'borrowed') one of these AO #10 lenses for quite a few years, close to 20+...the only reason AO had to stop selling them in the USA was the fact they weren't made of 'tempered' safety glass. These are fairly easy to identify...they are/were made of 3 layers of various glass that was laminated. If you have a 'silver' or gold plastic or solid 1 piece glass type filter plate...it is likely not the same thing.Last edited by dougspair; 09-11-2014 at 03:09 AM.Dougspair
