Being a Farmer sometimes requires me to weld rusty or painted steel or cast that I cant get to in order to clean it, and have to occasionally have to weld galvanized steel. So my question is does anyone use a 3M 6000 respirator under a Miller Digital Performance Hood?

I use the 6500 Large 3m half mask respirator under my miller classic. My employer has a great fume extractor for me but there are times when I'm welding long pieces of mufflers or converters that have a segment that sits outside the effective range of the fume extractor and the respirator comes in extremely handy. Then again i feel that for the most part wearing the respirator suits my welding style most, i always have my head in a position to see the arc closely. I think you are thinking very proactive about your long term health. kudos' to you brother.
