    Yes, I've seen that too, and thrown it away. The Radnor wire was a new roll bought in the middle of a project.

      My Miller machines are pretty solid machines, the 2007 MM180 runs Lincoln Innersheild ,030 211 flux core, and the 172 Challenger is loaded with Lincoln's L56 026-024? The New wire from Weld City could be Lincoln wire.

I definitely recall folks complaining about the newer wire from Harbor Freight (the old stuff made in Italy was good).

        Edit to add: thanks for following up! So often people find a solution and don't circle back to let us know.
        It is VIKING .035" ER70 S-6. Made in Vietnam. Just over $2.00/Lb. We've run almost #100 of it in pulse with all the above problems. The monumental difference with the L-56 left my head spinning.

        I spent a good amount of time badmouthing the MM255 here. I felt I owed an apology to Miller. It really IS a solid machine.
