So I just bought this miller 211 mvp with auto set. I have never had an auto set before, but I have been getting porosity when using the auto set expecially when I first start the weld bead. When I use the manual settings I don't seem to have this problem. Am I doing something wrong so I am running .035 flux core (radnor branded),I weld in and outside my shop.and yes I am running the correct polarity (I tripple checked that.
