Lincoln VS Miller

admin

Hi all. Thanks for letting me in here. I'm getting ready to outfit my class with new equipment. I've narrowed it down to the Lincoln Powermig 350 mp or the Miller xmt 350. Are any of you guys using these or have used both? Thanks for any help.Joey
Reply:The Lincoln Powermig 350 is a mig welder, so the wire feeder is part of the unit. The Miller XMT is an inverter that will stick, TIG, MIG, or actually weld any process that you want as long as it's a DC process. The only thing I can think of that the XMT won't do is AC TIG. I love the XMT that I have in my shop but I can't use it's full potential here since I only have 240v power. If I set my XMT at high amps and run big rods it will kick the breaker. If you could hook it up on 480v that would let you crank it up without issues.I just looked up the Lincoln and it is a CC/CV power source that will do all DC processes, but it comes with a built in wire feed. Both of them will do all the DC processes but with the XMT I think you will need to keep in mind that you gotta get a separate wire feed unit since there is no built in wire feed with it like the Lincoln has.Last edited by NBS Welding; 07-21-2014 at 01:19 PM.
Reply:NBS Welding - that power mig 350mp is cc/cv machine.I've never used one though so I can't say how they compare.

Reply:Yes sir Dave I had to edit my post. Once I looked it up I realized my first post was wrong.
Reply:You are going to have more programming with the PM-350. Syn. short arc is available and not available with the XMT machines.. If you get the XMT MPA model , then you get advanced pulse with the Miler machine. PM-350 is a chopper machine, so probably better in long term reliability overall..

Reply:Hello Joey, if you are challenged on space and need mobility, the Lincoln set-up(being an all-in-one) is likely a good choice. The Miller 350mp or 350mpa is much more versatile and also much more expensive. But I don't feel that comparing these two is apples to apples as well. The Miller is industrial oriented and the Lincoln set-up is generally used in a slightly different fashion. Check with the LWSs in your area and see what sort of pricing that they can do for you on these. Both Miller and Lincoln have educational pricing options that should help to save you a lot of money over the regular retail. I am biased towards Miller and in our shop we have (8) XMT350mpa's, (5) XMT350mp's, (3) XMT450's, (14) XMT304's, and a 352 Invision. All of these machines have run flawlessly for us and have not given us any electrical/mechanical issues. Most of the machines have either S22A feeders, S24A feeders or S74 MPa plus feeders attached to them. We've got a couple of spool guns that are set-up to operate from any of them and also a couple of push/pull systems.We don't have any Lincolns anymore, other than a Lincoln SA250 diesel, and any of our additional machines are of the Thermal Arc variety. There are a couple of shops in our area that are using the Lincoln 350mp and they are aluminum fabricators. Unfortunately, they don't fully utilize the features of that machine for aluminum. The others are using the Miller version of it or the Invision system. Good luck and likely others will have a lot of good additional information. Best regards, Allanaevald
Reply:As said above, the PM350MP and the XMT are really two different animals since the PM350 has a built-in feeder and the XMT does not. Miller does not make a multi-process machine with a built-in feeder.Lincoln's closest equivalent to the XMT304/350 would be the Invertec V350 Pro. For the XMT350MPa, the closest equivalent would be the Power Wave S350.You may want to call your regional reps for both companies and see what they have in the way of educational programs. Also ask if there are other schools in your area using their equipment and how it is working for those schools.JohnA few weldersA lot of hammersA whole lot of C-clamps

Reply:@ Joey Poole - my shop has all BLUE.  But, ran a Lincoln 350MP for a week straight in OH last year. That machine is a beast.  Awesome arc output for GMAW and Stick.  Short circuit .035 w/ C25 and CO2 shielding, and axial spray'd w/ 90Ar10CO2.  Mild steel, stainless steel, and aluminum (w/ a Phython gun).  An excellent package! Heavy duty construction, beefy controls, and synergistic settings/parameters.  But, as others have highlighted not gun'a TIG with her.If you are hell bent on MIG'n (and stick work) out the gate, the RED "350" is AllIn.Last edited by ManoKai; 07-21-2014 at 10:51 PM."Discovery is to see what everybody else has seen, and to think what nobody else has thought" - Albert Szent-Gyorgyi

Reply:@ Dave - bro, didn't even read the spec sheet you posted.  Could of sworn that TIG wasn't available on the machine. Must have been caught up in da smoke.  Ha!  The "MP" stands for multi-process and you are correct.  Betch'a opted to not TIG with her.  Wow.  Well then, guarantee she TIGs just fine.  Note:  gun'a have to recall what Lincoln MIG machine was used for the training.  Mahalo for the *important* correction Edit:  must have misidentified the RED 350MP as a "350P" Ref: http://weldingweb.com/vbb/showthread.php...ler&highlight=, post #5.  Must have ran a 350MP and never tried the TIG feature.Last edited by ManoKai; 07-21-2014 at 11:16 PM.Reason: Nomenclature correction"Discovery is to see what everybody else has seen, and to think what nobody else has thought" - Albert Szent-Gyorgyi

Reply:Lift-arc tig works well on the PM series,but you get a whole lot of transformer ripple with one..It will get you by just fine, just not their strongest point... Esab-Milller choppers are much smoother in tig.....(from owning all three machines)PS-from above... Is there a box to check none of the above?Last edited by Brand X; 07-21-2014 at 11:35 PM.Esab/Lorch ET-220iEsab 160i caddyThermal LM-200 Lincoln feedersThermal Pee-Wee 85sThermal 60i- 3phase /RPC powered (Beast)Thermal Drag-gun 35CINE 1500 Klutch 140i
