I am considering purchasing a either a Lincoln Powermig 300 or a Millermatic 350MP MIG machine. I want to do stell fabrication up to about 1/4" or so. I also what to do alum. work for street rod projects. The latter will include 0.065 sheet up to maybe a little 1/4" alum work. I have other Miller equipment and am quite pleased with it. I've read the info. on the Lincoln unit and am interested in the pulse on pulse claims that suggests the Powermig 300 can produce a nicer looking weld on alum. Also, I have only single phase power available but I could get a circuit in to supply 220V at 100A. Can anyone who has used either of these units suggest which can do nicer looking welds on alum? Also, what gun choice would you suggest for this application? Thanks!!!
Reply:Both will do a very good job on both steel and aluminum. I think it comes down to the operator more then machines at that level of machines.I owned a python/prince,powermig and if I was not doing mig stainless I would probably go for the Miller 350 p for the better change over from steel to aluminum welding.I really like a true inverter arc on mild steel and have a feeling the Miller will edge it out in that area. It's spitting hairs again though.The Powermig still has a room to grow in it's programming with it's upgradable software.The powermig has way more adjustments to the welding parameters then the 350P That could be a + or a - depending on your outlook.
Reply:I'm in the same boat. I was dead set on the MM350P, then i started reading up on the PM350MP, looking at what it had to offer, and its a real toss up. The PM350MP has some pretty crazy technology stuffed into it (ie: Pulse on Pulse, and the ability to upgrade the software and waveforms). My only real needs for the ability to weld alu is that for tacking peices together which will then get tig'd up. But if i'm gonna do it, i want something that i can run everything from mild steel to stainless, ect,ect, all in one unit. But i want a really nice MIG unit that i'll have for at least 5yrs, and i know that they both will work just fine, but the added features of the PM350MP are sure a big selling point for me. Priced pretty much the same, the choice is even harder. And speaking of price, any idea what the PM350MP goes for with the python push-pull option? And does the PM350MP come with Pulse on Pulse, and pulsed mig, or do you have to buy those options in addition to the price of the machine? You have to add pulse mig to the price of the MM350P (+$265, and another $1,400+/- for the XR-Edge gun) Well, thats my deliema, any insight would be good.Thanks,Matt2002 VW Golf TDi1994 Audi S4
Reply:Both machines work really well.For tacking aluminum the PM350 has a #40 mode the the MM-350 does nothave. all the programming is built-in the Lincoln can be upgraded for freeon the Lincoln web site. Both machine really work great so flip a coin.Don't really worry to much about which machine you buy, becauseyou will be happy with either one. Nice units.I owned a 300 powermig and python and used the MM-350pbut only for steel. I watched the Aluminum welding with it andit works great.
Reply:Howdy Howdy! Original Poster!: The Power mig 300 is an older machine. The Power mig 350 MP has replaced it. In MY mind, the PowerMig 350MP beats out the miller 350P. Both can accept spoolguns or push pull guns directly without anything extra. I DO know the Power mig 350MP has 2 gas solenoids allready setup, and a 115volt plug on the machine. The Lincoln has the same Brains and software as my Invertec V-350 Pro advanced process, and MAN oh MAN it is sooo nice for Stick too! THe multi-process is way cool as a re-sale feature even if you might not nead it. The arc characteristics are sooooo sooooo nice, with adjustable hotstart, and arc shape! The tig arc is very very smooth as well, and the lift start is convenient. In my opinion, the reason to go with the Miller 350P, is that it is a little bit more user friendly IF your not that great with the computer / personal interface using just a couple buttons/knobs, or due to brand preference. Both units require a 240 volt 1 phase plug. I DO know that the pulse on pulse feature is wy way nice for those alluminum welds. I have seen this machine run in person, and the pulse on pulse beads look ALMOST Tig-like. The Lincoln has all the pulse and waveform stuff built in, and yes it's upgradeable. Very easily too. all at no extra charge. If money was not the main object, then I would go with a Python Plus push pull gun. The Plus means that it directly mates with the Lincoln/Tweco end on the lincoln machine as the Python push pull gun is manufactured bye MK for both Miller and Lincoln. MK has it's proprietary end unless specifically ordered with the Miller or Lincoln Tweco end on it. Cost is all about the same. Then I would get Standard 300 amp tweco gun for the steel process in Mig. Hopefully these links will work...I'll post the best Lincoln 350MP I've found yet. in both the Tweco gun (for steel mostly) and with the push/pull gun (for alluminum mostly). You can still run the alluminum through the standard tweco gun as well with a good liner, but it's not that great for a long term production envirornment unless you have the push/pull gun to prevent some binding. The same for both brands of machinesfor that.http://www.weldingmart.com/Qstore/p002756.htmhttp://www.weldingmart.com/Qstore/p002251.htmThere is one other option, if your cool with slightly used machines. I purchased my Invertec V-350 Pro Advnced process off of Ebay from a seller named Netsply for about 2,200$. Then you purchase either a push pull cabinet W/ push pull gun, OR you could get a push wire feeder NEW for about 800$ including gun. That would be teh LF-72. It would be synergic controls too. The main difference is Now you'd have power supply seperate from feeder, and a 425 amp max output. 3,000 for that setup in a push version roughly. The machines are about 1-2 years old, serviced through Profax welding out of Texas. Good guys. OK too much info eh? Can you tell I'm impressed with the Lincoln machine (in this class)? Good luck, whatever your decision! Brian Lee Sparkeee27
Reply:Howdy! Almost forgot spoolguns! A direct spoolgun setup wouldbe more affordable then a push pull setup, and can be left hooked up to either of these machines while a push gun is hooked up at the same time. I.E. you can have it set for alluminum and steel at the same time, making it very time efficient. Spool guns are around 4-600$ +/- That'd be the best AFFORDABLE option, in my mind without compromising quality or features. Brian Lee Sparkeee27 |
