    If you are having problems with arc-blow, just switch to AC stick (or borrow an ac machine). You can also try to demag the pipe, but it's usually not worth the trouble.

        There are basically two ways,

        Remove the magnetism altogether by heating material to the Curie Point, typically 1000C and allowed to cool in a zero field or reverse the local magnetism using externally applied fields.

        The alternative approach is to reverse the magnetizing field dynamically as the weld progresses.
