What number lense to use.

What number lens is being used out there when tigging ? How do you know when its to week other than eyes feeling scratchy next day.

Use a lens that offers 100% uv protection then the shade becames a matter of personal preference for the most comfort and best vision. My choice 9 for autobody sheet metal, 10-12 for most welding up to 250 amps or so.

i use a 10 for just about everything these days (structural welding 232 and 7018) and most of the time dark safety glasses under the hood.

when i tig, i normally use a 10, or if im under 100 amps i use an 8, with clear safety glasses. Get stuff that has 100 percent UV protection, your eyes are too important to damage.

I think it is a personal thing. I use a #14 for most of stainless tig work that I do. Ten years ago I started doing some long days tigging and even a #12 left me with headaches, burning itchy eyes. Another professional tigger I met (pre internet for me) turned me on to #14's and I have been so thankful. For tacking I sometimes put in a 12 or even a ten if I can't get to close. You can kind of get used to the darker lenses and then when you go back to a lighter one it is soo bright it hurts! My rule of thumb to pass on is to use the darkest you can.:cool:

most of the time i use a 10 for tig but now I getting older I find myself turning my helmet to 9 a bit more and i can't stand a dirty lens if its not clear I throw the old eyes are good as good as they once were and put a new one in it cost me money but I like to see what I'm doing I'm lucky now with my job I don't have to weld as much anymore one of the joys of being boss :D

I'm a 10 for most of the welding I do (all tig), but I keep a 9 and a 12 in my tool box in case the need arises for them
