Hi, The difference between a 12 and a 14 is the 14 is safe for looking at the Sun while the 12 is not. I would recommend you NOT use a #12 to view the Sun. See: http://www.mreclipse.com/Totality/TotalityCh11.html#Welder Patrick :-) Joe Borgione wrote:
Thanks Patrick;
I was just out and about and stopped by Wasatch Steel (3300 So, about 400 W.) The darkest welders lense they had was #12; they'd never seen a #14. I bought it none the less (it was only about $6.00). How much difference is there between a #12 & #14?*
