I currently have a KT auto darkening helmet and run a Hobart Ironman 230 welder. I have old eyes and need glasses to see both far and near. My problem is that I have difficulty seeing the pool and surrounding area properly when I’m welding and as a result it’s hard to keep my welds on track. Is it me or would switching to a more expensive helmet improve my ability to see a brighter view where I’m working? What is the difference between a $100 helmet and a $300 one?
