    Mike,

    The unit has plenty of control, you can fine tune it in just like the Millermatic 252's.

    I'm going to have to get down to the local LWS and give one a test drive. I'm curious the feel of the dial when setting the voltage. I just keep imagining that the knob will be very very sensitive as you have a limited sweep of the dial to go from it's lowest, to highest setting. If you have the same sweep as a smaller machine but this machine has more of a range of potential voltage range a given amount of movement on the dial would have to give a higher change. I'll have to try one.

    I just wanted to clarify a few things with regards to aluminum vs copper in the Millermatic 212.

    When designing the new Millermatics we talked to alot of customers and one of the things mentioned many times was "we love the arc, don't change it". Because of this the Millermatic 212 has the same transfomer and stabilizer design as the Millermatic 210. We did add some nice features and put it in a new case but the arc perfomance and that same reliable field proven design are still there.

    If you noticed the weight differences on the spec. sheets this is because the Millermatic 212 was weighed without the shipping kit and the Millermatic 210 was weighed with the kit. They are in the process of having the weights on the spec. sheets changed to include the shipping kits.

    If anyone has any questions on the new units please feel free to ask away.

    Thanks,

    Kevin,
    I know this is an old thread, but was surprised yesterday when I went to Miller's website and found that the 212 now has autoset. Someone from a Jeep board looking for a welder was very impressed with my welds and asked me what machine made it (I have a mm210) and I told him the 212 was an identical machine from a welding stand point. I had to retract my statement as I noticed it now has variable voltage.

    You had mentioned, and many people on fabrication boards all over the Internet that the customers prefer the amazing arc that the 210/212 machines produce. There's something about a quality tapped machine. It's like the argument of analog record vs. DVD's, or tube amps vs. electronic amps. On paper they seem superior, but they seem to lose a certain depth in real life.

    Does the 212 now have the arch characteristic similar to the 252? The 252 although an amazing machine, tends to have a softer arc compared to the 210/212. For short circuit welding a much prefer the sharper arc of the 210/212 over the 252 which is why I exclusively use my 210 for this purpose.

    I'm getting very nervous here. I'm afraid that the world has lost the amazing arc characteristic of the 210/212 with the release of autoset and infinite voltage. You may have done what in this thread you said was a priority of Miller's not to do... mess with a good thing. I can't say for sure since I haven't welded with a new 212 autoset... but if the characteristic is closer to the 252 then in my opinion you've lost a bit of the 210/212's magic.

    Kevin,

    Does Miller use aluminum wire in any of their transformers ?? I know they have been using aluminum wire in power transformers for many years but I don't know about welding transformers. Do you know when the practice started and with which manufacturer.

    I can't see how an aluminum wound transformer could change the arc. I can see how a filter ( I think your term is stabilizer if this is the same thing ) could have a profound effect on the arch and these can be tailored by design to certain needs. And as everybody probably agrees, Miller has the best handle on that for sure.

    The biggest differences I see in the two wires is conductivity, tensile strength, and expansion coefficient. To take care of the conductivity difference, a larger diameter wire is used when using aluminum and that takes care of the tensile strength as well. The larger diameter wire negates heating effect and electrical losses. That leaves expansion coefficient and that is, I think, how aluminum got such a bad reputation to begin with. Back in the
    70's someone had the bright idea of using aluminum in Romex wire. This is the type wire used in small appliance and lighting loads in residential construction. Problem was the aluminum, because of the greater expansion coefficient, became loose at the connections at the receptacles. The wire broke if the homeowner was lucky, if it didn't, it got loose and heated up causing a fire. If I remember they didn't make the proper allowances for the difference in conductivity as well, aluminum being only roughly 60 percent or so as conductive as copper. When houses began to burn down the learning curve on aluminum wire and aluminum connections became quite steep. They don't use aluminum wire in Romex anymore but almost all residential construction uses aluminum on the incoming service, heating equipment , and service for the stove. And if the price of copper keeps going up they will probably start using it in Romex again real soon.

    The connection problem with aluminum power transformers has been solved. They simply take the end of the wires from the transformer and tig weld them to a flat aluminum bar where any type of connection can be made, aluminum to aluminum or aluminum to copper. There are also compounds used with aluminum connections and connectors that take care of the problem as well.

    So I have some questions if anyone can answer them.

    1. How long have they been using aluminum in welding transformers.

    2. how many manufactures are doing it - is Miller one, what models. Is it possible some have been using welders with aluminum transformers and didn't know it and are telling friends they are the best welders around.

    3. And the question I would like answered most of all. How does an aluminum transformer affect the arc. The why part is what I would like to know . Htp makes the same statement about their copper transformers.

    The last question I would really like answered because I don't want to spend a lot of money on a welder I find I am not satisfied with and have to brood for many years because I made a bad purchase. I am getting too old for this kind of stress

    Thanks

    Regardless, it's good to hear that Miller saw fit not to "futz with" one of the best mig welders on the market.
    i'll 2nd that as its on my to get list. odds are good the 252 will be more than i will need or have $$ for. the MM210 has been on my need to get list for a wile and there was a small amount of concern over the 212. but incoming reports support the above statement. its still well spoken for.

    Kevin,

    Appreciate your setting the record straight regarding changes to the MM212.

    Think the original comment came from a "miller insider" regarding why the MM212 weighed (per specs) considerably less than the MM210.

    Regardless, it's good to hear that Miller saw fit not to "futz with" one of the best mig welders on the market.

    Clint,
    I have to agree with Archaic. I also have the 251/30A gun and though I probably don't have enough hours on it as he does, I am TOTALLY happy with mine

    I have had a MM251 with the 30A spoolgun for about two years now. In forty years of welding this is about as sweet a setup as I have ever had. Have owned lots of red and have nothing bad to say about them. But, the 251/30A is about all that I really want to use anymore. Sweet on mild, sweet on stainless, sweet on aluminum. With the exception of one M25 gun going tits up I have had zero problems with the 251 or the 30A and there are LOTS of hours on them.

    Thats nice to know since there was alot of talk about the alum transformers a while back.

    As far as the 3035 Spoolgun i use the crap out of mine with steel and alum wires and its great. But i did change the tip size to a standard 1/4-28 Miller tip by redrilling and tapping the head tube and i think that helped performance more than anything...Bob

    Thanks, Kevin.

    As most of you know, I opted to go with the HTP 2400 and RSG250 spool gun combo. This was not in my original comparison chart, but Jeff Noland at HTP talked me into it.

    I can't remember if it was Dda or someone else, but whomever mentioned a 20+ year old grudge with Lincoln, I'll be there in another 18 years! My beef is only 2 years old with them, but I'll be holding it for a while.

    I will say this: Miller's 3035 and HTP's RSG200 are made in exactly the same factory, on exactly the same production line. The only difference is the label.
    I will not say what country they're made in, but suffice it to say that quality control in that particular plant is EXTREMELY tight!

    Conversely, while HTP's RSG250 looks identical to Lincoln's MT250X spool gun, HTP's version is made in the USA under strict ISO guidelines and quality control; the difference being that Lincoln's equipment is made to the same specs, from the same set of blueprints, but made in a foreign country (south of us...) with very little quality control. I have independently verified this information.

    HTP offered me a 90-day money-back garantee if I'm not satisfied. So far I couldn't be happier with what I've gotten but it's nice to know that the HTP folks stand behind their products.

    For anyone not interested in the HTP, or maybe someone already has a Miller and wants to stay Blue, I would still recommend Miller's 3035 and/or MM210/MM212 to absolutely anyone who asked me!

    If you like the MM210 w/3035 Spoolgun, you should come on up here to VA and run my MM251 w/30A Spoolgun. You'll swear you died and went to Heaven.

    I agree with Sundown, I talked to a lot of guys with the 210/3035 spoolgun, and they are a lot happier with the 251/30A spoolgun. Waited a couple more months to get the 251/30A package

    The talk of the aluminum on the secondary side in the new MM212 is still making me nervous. I really hope the 212 doesn't end up being a lemon!!!

    The delivery guy was by today with my new Bernard gun but took it with him when nobody was home to sign for it. Nothing worse than knowing it is sitting in a delivery truck somewhere close and having to wait til tommorow to get it....

    I really do hope the 212 exceeds the reputation of the 210....time will tell I guess.
