    I'll say XMT350 MPa + D70DX is at the top of my financial possibilities... Probably even a bit exceeding it... :)

    Thanks a lot.
    We have few european brands here...

    Here is one example: TELWIN INVERPULSE 420 MIG,TIG,MMA, water cooled

    This machine (powersource, water cooler, separate feeder, trolley + acc) will cost me same price as I'll pay for MM 350P with delivery to Russia. But I think by features this machine will be closer to XMT350MPa (but only 350A on 40%)... or a LI PowerMig 350MP. It also have puls-on-puls but... no push-pull there :) The main weak point for me - 3 phase 380V only... MM350P & XMT350 have multivoltage.

    I believe it's chinese made but Italian branded. Any suggestions?

    I beg to differ...

    There are some crap and then there are some really good stuff from the land of slit eyes. My Chinese made welders take a beating every day and not a single problem experienced. Open them covers and the inside may put some good brand names to shame - substantial high quality pc boards, faultless wiring and everything on par with the best.

    If you are on a tight budget, it may be well your worth to consider these machines. Get a dealer to show you the insides of a Miller, Lincoln or Hobart, take note of it, go to a dealer handling quality Chinese stuff and let him open his machines and make your choice. Best test thought - test weld it... You may end up paying far less than half for an excellent machine. :cool:

    You may also be surprised how many of the well branded USA and European machines are in fact being build in China. ****, even my American upper high end Marantz hifi amplifier was built in China....:(

    many of the welding power pacs have link inside, to take taps for 380, 415 and 230 3 phase , usually I set up on 380, because although supply is 415, we used to get voltage droop, and therefore 380 was better.
    the main thing for you in Ru, WHO WILL FIX IT? is there an agent there?
    can you find my email address on the website and I may ring you when you get back St P

    Being in Australia reliability and back up service important down here as everything is 6-10 weeks away, what I like about XMT350 is can run of 10 or 15 amp single phase (240v) and be welding 10mm 5083 plate all day with out duty cycle problems. The auto line is great for power supply short fall ,no 415V.

    I agree with Wynard....Yes test is a great idea...ask the dealer to set up demo and leave for a few days for you to try ,putting it through its paces. The plate thickness you are using shouldn't be a bother with duty cycle.


    You can also run helium/argon gas mix to increase heat output ,but dont think you will require to do this,just another option.

    Remember the agent want to make the sale ,use this to your advangtage, get him to bring the models you are interested in so you can compare each one .....good luck

    Does anyone have experience with the Kemppi Kempact 3000 or the Fronius Transpuls Synergic 2700? How do they compare to the Miller XMT 350MP, besides the amperage? What are the alternatives?

    do you have power limitations?
    what size plate are you welding?

    Kempii have a beautiful system,great integral synergic pulse system,good control panel that is not too complicated......good push pull set up . most important is availablity of consumables and parts...they have nylon rollers that wear out with heavy use....teflon liners etc ... parts are hard to get in our local area,.......check your area

    Fronius TPS2700 is the pick of the pack for ali guys down here as they have good back up with plenty of consumables(tips ,shrouds etc ) and parts on hand....check your area
    set up with push pull system it is very portable & popular....good pulse system ,pulse on pulse, the control panel once familiar is very good set up.

    Both systems above are dedicated three phase machines and are multi process... .

    Miller XMT350MP is another great system ,it does n't have pulse on pulse, but pulse system is very easy and simple to use. This system requires seperate wire feeder ,plus lead kit ,so that makes it not as compact as the other two machines.....plenty of parts etc available ....check your area
    But it has auto line ,which allows it to run on single phase or three phase.
    It is also mult process
    Compare the duty cycle......
    all are very good machines.........depends on how much you can spend,....back up service and parts.

    Hope this helped .....

    orcaboatsaust: thanks for the information.
    it would be mainly for 3, 4mm and 6mm plates and 4, 5 and 6 mm extrusions.
    some 10mm plating for local reinforcements.
    Do you think that they are worth the higher price, for better finishing, higher welding speed and less distortion?

    is it a one off build ,or production ?
    I think they a great time saver for production ,because of better finish ,..etc .
    Thus paying for itself with the reduction of manufacture time. Production business a major benefit ...if it a one off build well your call on what you want to spend.

    Those plates sizes are not a concern for all the machines ,....

    my personal choice would be towards Fronius if 3 phase supply not a problem....
    good luck
