  • Millermatic 252 running 308L .035”

    HELP! How do I search old threads to determine why this brand new machine continues to have wire feeding issues!

  • #2
    There's a search box at the top of the page. Put in Millermatic 252 and read through the results. If you are using an old iphone it may not show up--its missing on my phone. Use a computer and you will see it.

      I can tell you that I personally ran MANY rolls of .035 308L through a 252 with zero problems. This was on a condensate return system we replaced. I had two helpers setting up one spool while I welded the one.
      14", 12", 10" and 8" along with various fittings.
      Also, hundreds more feet of 2" along with a bunch of 3".

        AERONCA41 Have an iPhone 6. Came home and tried the tablet...no luck until I flipped it sideways. Not a big fan of the new format, however the help is always adequate. Thank You.

          I searched near and far on the forum, everything I've read has been done.
          From changing wire brands to the spool tension, inspecting drive roll (alignment, tension, size) to changing liners, and replacing the contact tip .
          Continues to bird nest and feed slowly . Is there something more? also...no results for a hidden menu.

            I had a customer with the same problem. Try a larger dia liner like for an .045 it helped his machine...Bob

              There is a hidden menu. Turn the machine on while holding down the trigger. Viola.

                    Griff01, aametalmaster:
                    Been running the largest liner available.
                    Been taking “extra” time to ensure no bind whatsoever in the lead.
                    Cleaned and tensioned the drive rolls.
                    Replaced all small parts.

                    Checked for bind on the spool.
                    Adequete ground.
                    No loose connections.

                    All looks good and it still binds with the the slightest movement while welding.
                    Griff01...did you have a cleaner pad clipped to the wire inside? Wondering if this would provide a little lubrication for the wire running inside the liner. I don’t think my issue is anything else. I seldom use this machine but Id like to solve this issue.


                    Thanks in advance.

                      Without actually being there I am stuck what to suggest. I have run miles of SS over the last 35 years thru many Miller migs with zero problems. I also weld SS at home with my MM185 and a 15' gun and never any problems...Bob

                        No cleaner/lube used on this set-up. Something I failed to mention. There is a "pre-guide" (may be the wrong term) that can clog up and cause feeding problems. It is the first thing the wire passes through before the feed rollers. When we bought a MM251 a couple of years before getting the MM252, it quit feeding if the gun cable wasn't perfectly straight and then quit completely. I found the pre-guide to be completely clogged with copper "dust."
                        This was on the FIRST roll of ER70-S? used in this brand new machine. I actually had to use a drill to clean this crud out. Never had the problem again. It had to be poor copper cladding with that roll. I do not remember (for sure) the brand of wire and I'm not going to guess.

                        PS
                        I was close. The "pre-guide" is actually called a "wire guide."

                          griff01, aametalmaster,

                          Thank you both for the responses

                          I noticed that the wire guide was "highly warn"
                          I rotated it 180 degrees and that seemed to help
                          This machine has never seen anything softer than 308.
                          I will pick up a new wire guide in the morning and get to it Monday.

                          I'll post results next week.

                          Thanks again!

                            Also make sure the big nut holding the wire spool is loose enough. My brand new MM252 was too tight to let the wire spin properly. It took me almost a whole roll of wire to figure it out. That was about 6 hours of a big headache. Great machine after that. It made me almost a half million bucks. I did have to get a new gun for it as a 20" piece of pipe cut the other one in half..Bob
