I bought one of these about a year ago when Zoro had one of their 30% off sales.

I take off my normal glasses and wear a pair of reading glasses. In my opinion, seeing what you are doing is the most important factor in welding next to having the right machine. When I can see my penetration and see how fast the wire is burning, I can make a good weld. I don't use a stick much, but when I do it is a Trailblazer 440. I have cranked the lens up to 13 when I was burning big rods. But there too, seeing is a big factor in the integrity of the weld.
