  • New miller 211 spool gun issues

    Hello, first I'm not much of a welder but have been trying to learn mig aluminum welding, had a 185 then used a 251 with 30a
    Got bunch of 1/8 plate and angel scraps , now just got a 211 today and tried the spool gun a whole different feel, sound, and results!!! Burnt 6 tips in 15 min!
    Why does it seam so different that the 251? Not that I'm sure it will be ok but never had that much trouble with burn back?
    using 35 wire 35 tip standard wire. I saw in another post tonight, people talking about some mods and things to help with burn back ? Any help will help thanks!

    The 211 and SM100 are designed to run 4043. Keep the wire feed speed high.
    My opinion is that .035 is too large for the 211,I believe you'll have better luck wth
    .030.
    211/SM100 compared to a 251/30A is like comparing roller skates to a Cadillac.

      Tell me why? I don't understand ?
      if a welder has enough power why would one work better than the other?
      Thank you!

        Fishbum, I just got my 211 with the spool gun and had the same problems you are having. The tapered tips are the problem. Check with Bob, aka aametalmaster on this forum. He fixed my gun to use the standard mig gun tips and my problem was solved. Also the 4043 is the best wire I've found so far. Check out my latest post about no penetration. There's some good info there about this topic. I love my 211 now that I have gotten used to it. Keep trying, it will be worth it. You need to just send your gun barrel to Bob. He's the solution, and a great guy to deal with.

          Thanks, I saw that post! Lots of good info! Will make that contact with Bob,
          Is this something he is just doing or is he doing it for a fee? Doesn't mater either way just don't want to expect something. Again thanks!

            Thank you Bob! Did the tip mod and so far what a difference!! Ran about 20 test welds and no burnt tips!!

              I can't imagine why Miller makes them with the tapered tips. After Bob fixed mine its actually fun to use. At first I was ready to throw in the towel. Thanks again Bob.

                  So why does Miller not use your design?

                    5356 needs higher wire feed speed and more voltage than the 211/SM100 was designed to produce. .030 would take a lower voltage and wire feed speed and may work on lighter material.
                    Burn back on aluminum is aggrevated by low wire feed speed.
                    The larger the wire the higher the wire feed speed and voltage it takes to run it.
                    Does that help?
