So with the smoke rising, besides breathing and wearing the smoke not good for you, the smoke damages the lens. Shouldn’t you just have a fan to the side blowing the air across the work piece and smoke goes away from you and the gun?
I've seen guys walk out the shop like they walked out volcano from all the shards rust left on the from grinding. This looks clean and affective, over time it will definitely bring more then 8k and you maintained cleanliness. Time is money imagine all the time your save in prep and cleaning after!
