Well, here's a problem about lighting.... if the lighting is behind you, it can shine past your head onto the inside of your helmet, making a glare on the inside of the glass, making it harder to see once you strike an arc. I find that problem a lot when welding outside with the sun at my back. I have to turn the work so the sun is in front of me.
For small welding, I use a pair of dime-store reading glasses in front of my regular glasses, then my auto-darkening helmet. I have to get pretty close to the work to focus on the puddle. The wire-feed is so much easier than a stick welder for small stuff.
