    I don't think you really paid any more money because of the auto set feature. Since it now comes on all entry level miller mig units it has become standard equipment. A miller 175 was the same price point as the current 180 with a/s.

    Still be satisfied knowing you have a very useful, well built machine. I have been able to get decent welds with the a/s, just need to modulate travel speed, stick out, etc. I found that it was just as much dialing in to work as manually setting it.

      I don't think the charts in the manual are what Steve is asking for.

      I wrote Miller and asked them three questions:

      1. Do you have a chart that shows what the wire speed (IPM)is at any dial setting (10 to 100)?

      2. Do you have a chart that shows what the voltage is at a specific dial setting (1 to 10)?

      3. Do you have any articles which describe in detail exactly how the Auto-Set feature works? Not how to set it but how it works?

      Here is there answer:

      We do not have any charts saying specifically what wire speed and voltage you are setting on the front of your 211. For this type of machine the best way to set your parameters is by looking at the chart on the inside door of the machine. There are recommended voltage and wire speed settings for many wires, gases, and material thicknesses.

      The Auto-Set feature works by sensing the position of the two knobs on the front of the machine and setting the wirespeed and voltage to predetermined values for the wire size and material thickness selected. The Auto-Set feature was designed for use with solid steel weld wire and 75/25 gas.

        The reason that they won't give ipm <--> knob setting is that miller uses fairly agressive wire speed tracking (the wire speed changes when the power changes, even if the wire speed knob stays the same). Honestly that is one of the reasons I stayed away from their smaller machines before, I find it more difficult to set compared to some of the smaller Hobarts and Lincolns (which use little or no wire speed tracking)

          Your information would be true for the MM 135/ 175 or the earlier production run of the MM 140/180.

          The Auto-set MM 140, MM 180, and MM 211 do not contain the wire speed tracking circuitry.

          The early production run MM 140/180 allowed you to turn the wire speed tracking circuitry on or off. Allowing you to make the unit a constant wire speed machine if wanted.

            Interesting, I was wondering how that all worked out across the model line and which units had the wire speed tracking. I knew my 180 does not have it, but I have seen literature discussing 180's that do.

              I don't agree with you...

Talk about frustrating to the newbie home welding hobbyist! You pay a premium for an "auto set" feature that after ruining a bunch of metal you learn that the auto set feature really doesn't work well and that you have to learn to set the appropriate wire speed - voltage - metal thickness - type-of-weld combination through trial and error experience. OK, I accept that, but why did Millermatic build a welder that doesn't work as advertised? I would have rather saved the money and bought a 220 V unit without a worthless feature. If I'm forced to learn the machine by trial-and-error anyway, I'd rather have not paid for the auto set!
              I use my auto set all the time. But I know it is not magic. It gets me close and i adjust the ONE knob as needed...just means one less knob to turn to get a good weld...and God knows I need this as simple as posible.

                Thanks for some sensible feedback on my rant about Miller's &quot;AutoSet&quot;

                Let me start out by saying I really like my new MM211. However, the combination of me and the auto-set on my machine makes a bad team. If the auto-set was only off by one click of a knob, I would have no problem with that. In my experience so far, especially on thinner metal thicknesses, I've had to set the Auto-Set at least two settings down in order not to have to race through the weld or burn a hole in the metal.

                Now, I accept the fact that this is a combination of my welding skills as well as the machine itself. I try not the blame the arrow because usually it's the Indian that's the problem. Having said this, there sure are a lot of other "Indians" out there who seem to be shooting the same defective arrow!

                  Just like you'll find lots of meat lovers in a steak house.
                  Most of the market for the 211 is for hobby and newer welders, the ones who are just starting out or don't weld all the time. If you don't like the auto set, don't use it!!!
                  As stated I don't see you paid more for auto set over non, maybe you paid more for Miller over other brands.
                  Just my .02

                    Go2 is right. I CAN use the as feature. It is more of a hassle though, especially for thin sheet.
