Those Lincoln Idealarc machines are bulletproof. Put tons of 3/16 x 7018 rod through one where I used to work many years ago. Always cranked to the max and never one issue
Have been learning to weld the last few years and picked up a Lincoln 210MP. I’ve only ever used it for MIG so far, but as someone who doesn’t yet know how to gauge things yet I love that I put in the metal gauge and wire size and the machine automatically gives me a range.
