Look at how your room lights hit the work area, (seriously, it's often overlooked). Reflections from bright ceilings or shiny tools can amplify arc glare like crazy. Sorting that out first might make other fixes less needed, you know?
Mirrors are a game changer for sure. A dentist's inspection mirror on a long handle saved my skin more than once in those tight spots. The bendy neck lets you position it exactly where you need a second angle without craning your own head into a beam. Just watch for glare bouncing back at you from your own arc.
