  • 252 vrs 211

    Wondering if when using a spool gun
    if you get a different quality weld on Aluminum
    from different welders. Or is it just the person behind the gun? I have a 211 and don't really think I'm getting good welds from the spool gun. Does a 252 with 30a automatily weld better? Thanks

    96% weldor, 4% welder.

    But the question is insufficient to start the discussion. What is your level of experience? Post pictures of the weld, along with material type, thickness, and all machine settings, plus gas type and flow setting.

      I agree with Mac. I have been spool gun welding since the late 70's. I can do more than maybe the guy next to me because I have been doing it longer. And I do stuff most guys won't try. But the machine has some to do with it. I wouldn't do it with a 120v mig but yours should be ok on thinner parts just watch the duty cycle...Bob

        I switched to a 215 from a 211. The 215 does just fine with a 150 spool gun. I think the 211 would be very close to the 215 in regards to a spool gun. I had to cailbrate it but it works surprisingly well.

          Which model 211? Is it the older transformer machine or the new inverter based machine?

          I had the older 211 and it did not perform very well on AL with the Spoolgun but my Passport Plus ( inverter) is a dream.

            I've ran some smaller migs on aluminum and wasn't very impressed.
            I would say there is a huge difference between welding with a 211 vs a 252 on anything, let alone aluminum.
            Like Brocoli1 said, inverter arcs are much more friendly.
            I'm hoping Miller is working on a 250 class inverter machine as we speak!!

              That would peak my interest. This old MM250 is a beast, but sometimes frustrating with the harsh arc and tight sweet spot.

                        I cannot speak from personal experience between the two but my welding shop talked me into a 211 from wanting a 252 because he said some of his guys actually prefer the 150 spoolmate over the 30a. In welding aluminum, the bottleneck is the spoolgun not the machine and the 211 and 252 are rated similarly for aluminum capabilities.

                          But the duty cycle of the 211 will kill you on bigger aluminum jobs where the 252 will run all day. And I agree the spool gun is the bottleneck. But with a few mods the 150's spool gun will keep up. I have welded with mine for 5 hours straight working inside dump trucks...Bob

                              Yes it has been going on for more than 10 years. I started modifying the Spoolmate tubes for the standard Miller mig gun tips and not the puny threaded ones that come with it. Why stock 2 sizes of tips? And the larger mig gun tips help the gun feed the wire better because when welding aluminum there is lots of heat on them. The small tips can't take the heat as well...Bob
