    What they are used for and polarity is all in the numbers, look at a rod chart and it will even tell you what amps it can be ran at.

        If there AC it should be marked on rod ie.
        7018-AC if not on rod should be DC.

            6011 and 6013 could be run AC or DC,7018 would be run DC and 7018AC would be run in AC.

                I hope the link works, first time trying to post one. The Lincoln Electrode Guide has a lot of good information. Pages 36-38 should answer your questions on current and polarity.
