  • How long do drive rollers last?

    I know when to replace the liner, tips, nozzle, but no one ever talks about the drive rollers.

    I've got a Hobart 210 MVP, and I love it and it's new.

    I looked all over the net, and found nothing.

    The only thing I see is when it doesn't feed the wire no more.

    Someone a while back told me that a lot of birdnesting can damage them too.

    I've only birdnested mine once, because I set the feed rate too high and was welding wrong. User error.

    But I'm curious... because I never see this mentioned.

    Thought provoking!

    Basically, my belief is they are not considered a "Consumable" like the other parts you mentioned.
    The only usual reason to change one is for wire size or type. Like an 023/030 for an 035 or a smooth for a notched type for Flux Core.
    Other than that the ones on the open accessory wire feeds at work seem to run through many pounds of wire in a dirty Industrial Welding Environment with no Ill Effect.

      For home use , you may never have to change the drive rolls. I have had to change wheels, as they were visibly worn. Most of the time the drive wheels I have changed were on machines that were used 12 or more hours a day 5-6 days a week, or/and machines running stainless for extended periods of time. There is no magic number the drive wheels must be changed within, even in a professional shop. I would not worry too much about it in the home setting

        rollers are long life

        We have numerous Lincoln 215's at work and these are used for production work with 33# rolls of wire. Maybe 1 roll per week per machine. I have been using these machines for 8 years. Two are only about 6 years old. All have original drive roles. Maybe once or twice a year there could be a slippage of the wire and it is usually caused by a flake of something stuck in the groove. Just run your fingernail through the groove a few times if you see any copper flakes. Serrated drive rolls for flux core could leave a lot of metal dust in the drive area so blow it out occasionally. I imagine stainless could wear drive rolls faster.
