[QUOTE=IC2;336373]"I have multifocal glasses (no line trifocals plus). Then to top it off, they are auto darkening(need these to see outside) so whatever ultraviolet light gets through, they darken up. Then to make it difficult, I have a different 'scipt and a major and different shaped astigmatism in each eye - all of which means I can't use the Wally World off the shelf specs. I'm resigned to what Uncle Bob has suggested - lots of cut off and grinding wheels and an occasional weld bead that runs wild".

I have the very same problems. I've tried several different remedies like all of you but always come back to "..oh crap I missed the seam again.." . TIG is easier than mig just because I have to position everything and get in close. No more laying on the floor, mig gun at arms length trying to reach what I should have put on the bench in the first place.
Ain't getting old just so #&%&$^* much fun
