Maybe I'll try to fix it, but what is the best replacement these days?
Reply:Answers are left wide open without a bit more information about your needs.A direct replacement from Miller would probably be the MM 252.City of L.A. Structural; Manual & Semi-Automatic;"Surely there is a mine for silver, and a place where gold is refined. Iron is taken from the earth, and copper is smelted from ore."Job 28:1,2Lincoln, Miller, Victor & ISV BibleDanny
Reply:me personally... what died in it? Major failure, or minor problem? Contactors and rectifiers would be minor... transformers and control boards, that'd be major...
Reply:I use this for structural welds in steel up to 1/4". As to the failure, I don't know. The wire feed works, but there appears to be no OCV. Suggestions for repair or replacement would be appreciated.
Reply:how savvy are you with operating a volt meter and circuit diagram? On miller's website www.millerwelds.com - you can get an owners manual for it ( if you don't have one already ) they have a wiring diagram in it.You just got to find out where the power comes from and don't go any further.
Reply:As poor performing of unit as the old Millermatic 250 is (harsh arc and poor weld puddle wet out), especially when compared to the 251/252 that has replaced it, if I owned a MM 250 and had the opportunity to convince the wife that it was dead , and I needed to replace it, I wouldn't waste one second trying to repair the unit. Instead, I'd head to Airgas as quick as I could, and replace the old MM 250 with either a MM 252 or ESAB Migmaster 250. Both of these are a far better performing unit then the MM 250.
Reply:I bought my wife a $5k embroidery machine yesterday, so she suggested that I replace my MIG unit! I'm thinking about a Miller MM350P or a Lincoln PM 350. Any opinions? I have a Miller TIG machine, so the TIG functions on the Lincoln aren't a consideration
Reply:OMG... Your wife is the bomb! I highly recommend you rush to your local welding supply while the wife is still in a good mood, drop $5K on a new MM350P, with the new Aluma-Pro push-pull torch, spend the rest of the day welding with it, and post your results!! We'll all be feeling the joy with ya, brother!

Reply:By the way, for my opinion about the MM350P, just look at the last line of my signature.... Oh yea, and hopefully, sometime in the next month, I too will have a new MM350P in my garage!

Reply:well hell, if you already have permission... that changes things. donate the dead one to a local teenager who might be able to fix it and use it.

Reply:My vote is for the Miller 350P. Back a short time ago, I was pricing a job that would have required a good mig welder. I didn't get the job but I did a considerable amount research and found that the Miller 350P was a very good choice.Miller DVI2Lincoln Precision Tig 225Thermodynamics Cutmaster 38Everything else needed.

Reply:Thanks to all for the info! A Miller MM 350P it will be! Hopefully this will be the last question: What is the difference (if any) between the "Aluma Pro" and "Python" torches? Can these torches be used for steel too, or just soft alloys?
Reply:Both torches can feed aluminum as well as hard wire. You will need a steel liner for the Aluma-Pro and a steel lined conduit for the Python or the hard wire will wear out the soft plastic liners both torches come with fairly quickly. However, the 350P comes standard with a regular mig gun (the Bernard QGun) that is set up for welding with hard wires. Seeing as you have to change the wire roll in the machine to swap between steel and aluminum welding, you may as well just swap the torch at the same time and keep the push-pull torch's wire conduit set up for aluminum all the time. It is very easy to swap between the two torches, just remove the wire, unplug the amphenol connector, loosen the knob that holds the torch's power pin connector into the feed mech, pull it out and insert new torch. Takes only a couple minutes, not counting time for removing and re-feeding the new roll of wire.Both torches appear to be very similar in price, within about $100 of eachother for similar setups, going by the msrp's.The Python is made by MK Products (makers of the original Cobramatic push-pull aluminum wire feeding systems) for Miller, as well as Lincoln. MK also sells them seperately, and as part of one of their own aluminum feeding systems. It is a tried and true torch, works great, is durabe, and parts are readily available, both from Miller and from MK. We have 3 of them on the machines at work and I have one here at the house I have used off and on. I intend to use it on my new MM350P, when that time comes. The XR Aluma-Pro appears to be possibly an in-house copy of the Python, with upgraded features. I do not know who makes it. From looking at the schematics of both, they appear to be very similar, but not the same. I have not got the opportunity to physically compare them side by side.Upgrades for the new torch include--A new wire conduit with replaceable plastic liner, so when the liner wears out, you spend $25 on a new liner instead of $100 on a whole new conduit. This is the new feature I am most excited about. I am trying to find out if I can use this new Aluma-Pro conduit/liner in my Python. If so, that will be great! The Aluma-Pro also has a set of easily removeable connectors at the torch end of the control cable, so you dont have to unsolder each wire inside the torch if you have some need to seperate the torch from the control cable. I don't know why one would need to do that unless there was a major problem with the torch or something. Anyhow, I find it an interesting feature.Miller advertises a new feature of the Aluma-Pro is an alloy-specific wire drive tension adjustment on the torch. To tell you the truth, this adjustable feature is nothing new. The Python has always had wire drive tension adjustment on the torch. The ones we have at work, we had to disassemble the torch handles to get to the adjustment, then we drilled a small hole in the side of each torch's handle right over the adjustment screw so now we can easily access the adjustment with an allen wrench without disassembling the torch. My Python came with the hole already there. I don't know why Miller didn't provide the hole in the handle to begin with. The Aluma-Pro's adjustment has two positions, 4043 and 5356. On the Python, the adjustment is variable allowing us to set it however we happen to like it.The Aluma-Pro is available in water-cooled version as well as air cooled for the MM350P. The Python is also available as a water cooled torch, but so far as I know, not from Miller for the 350P, only air cooled in that application. MK sells both air and water cooled versions of the Python. The Python has a 200-amp 100% duty cycle as an air cooled torch from Miller. The Aluma-Pro is rated at 300 amps, 100% for the air cooled and 400 amps, 100% when used with a water cooler. If you intend to weld alot of thick aluminum, water cooling is what you want. At work, we weld continuously with our air cooled Pythons all day long and have no problems with overheating, but we are only welding thin gauge aluminum at low amps, far below the torch's duty rating. I intend to water cool my Python when I set it up for the new 350P, using Miller's new water-cooled power pin connector assembly from the Aluma-Pro, if my torch and their connector will connect to both ends of the same wire conduit. Everything else shouldn't be a problem, I hope....The wiring on both torches is the same, except for the Aluma-Pro has an extra jumper accross pins H and J of the amphenol connector with a 5R resistor. As far as I can tell, this is how the 350P knows if you have a Python or an Aluma-Pro. Other than that, it doesn't appear to serve any purpose for the operation of the torch. Potentiometers appear to be the same in both torches. The motors may be different, but not sure how that might effect the operation of the torch. I would like to hook up an Aluma-Pro to one of the machines at work to see if it welds any different than our Pythons. My guess is there won't be any significant difference in how the two torches weld.The Aluma-Pro is available in 3 lengths, 15', 25' and 35'. The Python comes standard in 25' length from Miller. MK does offer the Python in 15', 25' and 50' versions too. I don't see why one couldn't special order a 15' or 50' Python made for the Millermatic when ordering the new machine and gun. It would probly have to be ordered from MK, taken care of by your local Miller dealer where you are purchasing the machine. I like the idea of a 15' torch. 25 feet is alot of extra cable to deal with if you don't plan on using it. The 350P only comes with a 10' ground cable, so if you want to really use the extra torch length, you'll need to buy a longer ground cable for the machine. I would prefer if my torch, and the ones at work, were 15' instead of 25. We never use the that extra 10 feet of cable and it causes more hassle than it's worth. But, it costs alot of money to change to a different cable length after you already own the torch, so I'm leaving mine alone. I will probly put a 15' ground cable on my new 350P to match the length of the standard 15' Bernard mig gun. I have done that on 2 other of my machines and it works good for me.I will be ordering my new machine without the push-pull torch, since I have one here already, but if I didn't, I would be really torn between the Python, which I like, know and trust, and the new features of the Aluma-Pro, which I am not sure of it's quality or reliabilty, or where it's made. I would want to see them both up close and personal before making a decision. Barring that, I think my first choice would be to special order a 15' water-cooled Python, and if I couldn't do that, then I would consider a 15' water-cooled Aluma-Pro instead and hope that the torch is as durable, works as well as, and is as easy to get parts for as the tried-and-true Python.I guess you could say, the jury's still out on the new torch, for me anyways.Have fun with your new machine!!

Reply:I have to add that I did visit MK's website, www.mkproducts.com, looking for information about the new torch. I thought at first it might be an updated model of the Python, since it looks so similar, but MK does not have any information about any new models of Python, or any other new models resembling the Aluma-Pro. That leads me to believe the new torch is not made by MK. I have not talked to anyone at MK regarding that yet though, so I could be wrong. I don't know who else would make it. As far as I know, Miller is not that into making their own torches, so I'm guessing some other company makes it for them if it's not MK. I should be able to find out something about it when I call MK next week to ask if the Aluma-Pro's new wire conduit with replaceable liner will fit into my Python torch. I'm sure hoping it will...Last edited by DesertRider33; 12-24-2007 at 06:43 PM.MM350P/Python/Q300MM175/Q300DialarcHFHTP MIG200PowCon300SMHypertherm380ThermalArc185Purox oaF350CrewCab4x4LoadNGo utilitybedBobcat250XMT304/Optima/SpoolmaticSuitcase12RC/Q300Suitcase8RC/Q400Passport/Q300Smith op
Reply:I ordered a MM 350P withe the Bernard MIG gun and a 25' Aluma-Pro gun as an accessory. Strangely this was cheaper than the 350P with the Aluma-Pro and no Bernard gun! The weld unit will be here the middle of next week. One more question: What is a reasonable size (gauge) for a ground cable for this? I want to replace the tiny cable that is supplied with a twenty or twenty-five footer.RichConnecticutLincoln SP-175 PlusMiller Dynasty 200 DXMiller Syncrowave 250Miller XMT 304Miller Millermatic 350PHypertherm Powermax 1000
Reply:They get alot of $$ for the push-pull torches sold seperately. I see they advertise a package with the Aluma-Pro, so it doesn't surprise me it's cheaper to buy it in the package deal. Let us know how you like the Aluma-Pro torch. The Bernard QGun is a good torch. I like the one I put on my Passport.1/0 cable should be enough for 25 feet.MM350P/Python/Q300MM175/Q300DialarcHFHTP MIG200PowCon300SMHypertherm380ThermalArc185Purox oaF350CrewCab4x4LoadNGo utilitybedBobcat250XMT304/Optima/SpoolmaticSuitcase12RC/Q300Suitcase8RC/Q400Passport/Q300Smith op
Reply:As an update, I called MK and asked about the Aluma-Pro. They do not make it. They did not know if an Aluma-Pro cable would fit a Python but said they doubt it. I will have to call Miller next week for the final answer on that one.MM350P/Python/Q300MM175/Q300DialarcHFHTP MIG200PowCon300SMHypertherm380ThermalArc185Purox oaF350CrewCab4x4LoadNGo utilitybedBobcat250XMT304/Optima/SpoolmaticSuitcase12RC/Q300Suitcase8RC/Q400Passport/Q300Smith op
Reply:Go buy the miller. You've got the go-ahead. I wouldn't waste anytime. Trust me coming from experience the wife's mind changes suddenly and without notice, so get your *** to the welding supply and buy before the window is no longer open......of coarse this is just my opinion and really holds no water
Reply:i think if you could find a used mm35 you would be better off i love that machine its got the juice to get the job done and makes a smooth weld or even better yet a mm cp250 those are awsome machines as well
Reply:He already bought the machine guys... ...I bought one too! Heimbuck, I know what ya mean about the CP250 power supply. I learned aluminum on the old CP250TS machines we use to have at my work. If I had 3-phase power at the house I would of kept the one I bought from them after they upgraded to new machines. I kept the feeder and sold the power source.MM350P/Python/Q300MM175/Q300DialarcHFHTP MIG200PowCon300SMHypertherm380ThermalArc185Purox oaF350CrewCab4x4LoadNGo utilitybedBobcat250XMT304/Optima/SpoolmaticSuitcase12RC/Q300Suitcase8RC/Q400Passport/Q300Smith op
Reply:I was a little late, but my XMT 304 is hard to beat and will workwith any miller feeder I have seen, and it does so much more than just run wire.The difference between art and craft is the quality of the workmanship. I am an artist.
Reply:An inverter welder like a XMT will give you the smothest weld because it is as close to pure DC that you can get. The good thing about the millermatic 350 is that it is basicly a XMT with a feeder built into it. It's a nice machine. |
