    Default Millermatic 211 wire feed

    Guys Iím wondering if anybody can help out with this, my MM 211 started having problems feeding the wire out of the gun, so I opened the door and could see it was clearly slipping and wire was not feeding out. Anyway, I checked the tension it was on 3 so I put it at 4 with not much help, checked to make sure I had the right side of die for the .30 wire I did, then checked the spool itself to see if it was to tight, that looked fine in fact (Iím using a 10lb roll of .30 wire) the lock nut in the middle of the spool was only on hand tight. Anyway, then I changed the tip in the gun, not much difference. Tried different wire speeds no help. So after checking things out for awhile it all of the sudden started working fine again no slipping? So any ideas why this would happen? Could there something wrong with the drive mechanism already? I just bought this MM 211 about 2-3 months ago.
    Thanks for any help or suggestions you guys have.

    There are smarter guys on this forum than I for sure, but I can tell you what I look for.

    I released the idler roll, trim the ball off the wire and drag the wire back somewhat to see if the liner is the issue, as there may be a kink or clogged with dust. I may remove the wire completely and blow out the liner with compressed air.

    Then I look at the groove in the drive roller to see if it is the correct one. Mine are v groove for hard wires and u groove for soft wires.

    I also check tip to see if the wire is dragging on it.

    I hate when this happens, so good luck.

    Default The other way also.

    What shovelon said, and clean the grove in the drive rolls. release the drive rolls and pull the wire through the gun, does it pull smooth and easy?, could there have been a kink in the wire?
    Sometimes there is a berry that gets in the tip that binds the wire.
    The wire guide could get full of dirt and cause the wire to drag( that happened to me, I could not see day light through the wire guide).
    Good Luck,

    Default thanks

    Thanks for the input, yes it does pull through easy cleaned the grove, it has not happened again yet but have not been using much the last few days. I was wondering if I have the 10 lb spool on wrong but it looks pretty much idiot proof, how tight do you turn the lock nut in the middle of the spool, I imagine just tight enough to still have the wheel spin freely of course. How tight do you guys tighten the drive roller on the 211? Mine is at 4 right now with .30 wire. I'll see on tue/wed when I'm off and using it all day in the garage.
    Thanks

    Default Bird's Nest

    You want the wire to slip if it becomes blocked. Better to slip than to make a bird's nest. You should blow out the liner when changing wire rolls.

    Tighten the brake nut just enough to stop the roll from unspooling. Speaking of unspooling, if the rolls does unspool, that will cause feeding problems until you get back to the neatly wound wire.

    I don't have a 211 so the numbers mean nothing to me.
    May someone with a 211 could jump in here.
    Good Luck,
    Bob

    Don't remember the number off hand but mine is most of the way down on all size's of wire. Most of the numbers are covered.

    Default clean wire

    If you determine that dirt is building in your gun then prevention is something to consider. A wire cleaner should be used before the wire enters the gun. I use a tampon and clamp it to the wire but there are other applications.

    Have done everything suggested so far and its better but, its happing once and a while still, have not been on the form in a while so I just saw the post where the tension is all the way covering the numbers so thats what I'll try now maybe this whole thing is just that its not tight enough after all.
    I'll update later.
    Thanks as always for the help guys.

    Make sure your holding the gun lead strait as possible. I don't think you would need a new linner yet unless it's kinked. Blow out linner, make sure it's clean.
