I'm a crap 'art school' welder (MIG & TIG). One of the issues is that don't do it regularly enough to get very good at it, so I forget the proper settings, etc. But the other really big issue is that I have a lot of trouble seeing the path I am trying to weld along.

I use an auto-darkening helmet and use "cheater" glasses but it is often still too dark and I will "miss" or wander off the seam I am trying to weld. One hack I've tried is to draw a chalk line along the seam or path and that helps a little (though probably not great for good welds but I am not welding pressure vessels ;-)

Is it just me and my bad eyes or is this a common issue? I'd appreciate any tips.
