    Flux core welding help

    Whenever I switch my polarity to dc- for flux core wire I seem to get worm holes some kind of fierce. But when I swap it to dc+ It seems to weld fine. Does it really need to be on dc- for flux core? I can lay down some decent beads on dc+. Thanks in advance!

    most flux is DCEN. There may be a few exceptions but look at what flux you are using. It will say on the label.

    Are you running gas?
    4T or not 4T, that is the question.

    I welded with my lincoln without reading to change the polarity so I was on DC + the whole time and it worked just fine too
