Thanks, PJ. Agitation is precisely the way I would describe it also. I can picture what you are saying if I think of it as water currents competing.
I was trying to follow the instruction that I think was from Dale somewhere, about putting in a back baffle to prevent gasses from pooling behind the torch or down behind the table. Correct me if I am wrong here: I was out to lunch doing that since my makeup air is back there. That would only be correct if my makeup air was coming mostly from the oppsite side of the room, right?
I will try what you say! I'll let you know the results.
