    Default XMT 350 CC/CV & Optima Pulse vs XMT 350 MPa

    Which is better, a XMT 350 CC/CV with an Optima Pulse control or a XMT 350 MPa? I ask this because I have the XMT 350 CC/CV and am considering combining it with a possible Optima purchase for use with my 30A Spoolmatic for use on thin (17 or 18 ga.) AL . Is the MPa a whole bunch better, or just the same?

    Come on, doesn't anyone (even a miller expert) have experience with the 350 MPa?

    I use a XMT 350 MPa with a 30A Spoolmatic on aluminum daily at work, mostly 1/8" Alum and thicker. It's a great machine, the thinnest I have welded is 14 ga Alum. (If I remember correctly)Should have used a spool of smaller filler but didn't have any, still seemed to work well though. I have no experience with the 350 CC/CV so I can't make a direct comparison, sorry.

    Thanks very much for your reply. Have you ever used the 30A with a Miller Optima pulser connected to any power source? If so how did it compare with the pulser built into the MPa? I'm trying to decide whether to splurge on an Optima. I might get an Optima if it's pulse abilities are equal to or better than the MPa's.

    No sorry I have never used the Optima pulse control, hopefully someone else can help you out more.

    Thanks c wagner for your response. Anyone out there with experience on the XMT 350 MPa/Spoolmatic as well as with the Optima pulser/Spoolmatic?

    You should contact the miller mig department directly. Ask them the differences between the mpa and optima pulsing programs. I'd betcha the mpa wins. Then if you don't believe them, contact your distributor and have them set it up and run it yourself.

    Default Optima VS. MPa

    Your welding application is rather demanding, thin aluminum material. I would pick the XMT 350 MPa over the Optima. The MPa has a very stable arc at short arc lenghts, which is what you need for thin Aluminum.

    If you going to just do a little project and never weld aluminum again, then go for the Optima and save some money. If your doing a big project and aluminum is becoming a material you weld frequently, go for the MPa, you will be much happier.

    Thanks

    Ken,
    How about comparing the MPa to the MM 350P on a wide range of aluminum from gage to plate? If we disregard the push/pull offering that the MM 350P has and used both with spoolguns, are they similar or is there a clear winner--and why?

    thanks,

    Thanks Ken for the insider advice. That's just the info I was looking for; question answered.
