UPDATE: I finally did some welding this evening & this setup works better than I could have imagined. NO fumes, NO smoke. I even tried welding without a N95 mask (that's all I could fit under my welding helmet) - I don't need a dust mask anymore. The 4" system very adequately pulls everything out almost instantly - I'm loving the new setup!! VERY SATISFIED. I wish I would have done it years ago.
Glad it works for you.
As I get older (wiser?) I find myself trying to be safer with stuff like that. Safety glasses, nitrile gloves, hearing protection, knee pads, etc. 20 year-old me would have not wanted to spend the extra few bucks on that type of thing, and would not have used it anyway....
