    Just wondering which you would buy primarily for mild steel.

    I only have single phase, so can’t really find a quality product much
    bigger than 250 amp in single.

    Any comments or recommendations in this price range.

    Thanks

    Are the above machines not that common then.

    I have no knowledge of the Kemppi, but I do have the Lorch.

    I’ve not used it a huge amount, but from what I’ve seen so far it’s great. I need to sort a 32A supply for it yet so I haven’t been able to turn up the volume but on 16A I have no complaints. It has a massive 4 wheel drive wire feed mechanism, and a really handy courtesy light. All in all it’s a brilliant machine and I’m looking forward to the Xmas break so I can get a decent supply wired in for it.

    As I said I know nothing about the Kemppi so I can’t make any comparison.

    Thanks for commenting. Yours is the pro control model with the 4 rollers then.
    I can’t find much info on them other than no complaints, there are videos of the larger
    models, which really weld well.
    Whereabouts did you get yours.

    I bought mine second hand off another forum member.

    As mentioned above chat with @matt1978 - he’ll be able to give you whatever info you need and he probably knows a bit about the Kemppi too.

    I haven't used one, but had a good look around the Kempact range, and used our Kempomats at work quite a bit. They are nice machines, well designed for compact storage and really easy wire changes (in fact, TOO well designed, they don't look like a welder any more!)
    Only flaw I really didn't like was the big wraparound front hinged lid is made of plastic and feels a little flimsy. No idea how it would stand up to loads of abuse.

    It's Kemppi, so it's gonna be really smooth and lovely to weld with. But then, so is the Lorch.

    If you're comparing them, compare the Lorch control pro version, not the basic.

    Thanks Mankul, yes, I found out about the difference between the Lorch Control pro
    and basic.

    Not much information available regarding the Kemppi Kempact,
    other than it seems to come in Two variations too, the RA 251A
    and the 251A, the later is more expensive from the same shop
    over the RA 251, I think it’s the control panel again that is different.
    Not much information regarding how the different Control panel
    actually effects the finished weld, maybe it doesn’t and is just a
    synergic setup for convenience over a manual setup on the RA version.

    According to the literature the 251 comes with a 2 roll drive (its a pretty nice one though) and two variants - 251R (regular) and 251A (adaptive with synergic settings, easy setup etc)

    The control pro Lorch with it's 4 roll feeder is pretty nice looking. Will be easier to feed aluminium, if that's ever a need. Other than that, I'd go with whatever deal you can best get from a local supplier...

    Kemppi kempact 251a. Aka the pressure washer.
    Not remotely in the same league as an Mpro. My opinion is obviously bias towards the lorch but honestly and truthfully these two machines are at different levels of the industrial spectrum. I work regularly with a couple of distributors that are often swapping failed pressure washers out with the Mpros.
    Don’t get me wrong kemppi make a good welder and some of their gear is industrial spec but the kempact pressure washer isn’t in that list. If this is the short list then my advice is definitely go 252Mpro. It was built to go to war.

    Hi Richard, thanks for your honest opinion. I agree they are very different, transformer
    versus inverter, never seen either up close, but again, metal versus plastic.
    I like the Lorch myself, just counting the Kemppi as it’s the only 250 amp single phase
    mig I see from a well known brand with similar spec and duty cycle.

    I wrote off one of those pressure washers in about 3 months running at a previous jobs

    Mpro is a lovely machine.

    inverter migs can be just as reliable as transformers. I just haven’t heard great things said about that particular one.

    I've had an m-pro 252 for a couple of years and it's been fine.

    I have used it on aluminium and the settings were good...i now keep a seperate euro torch with a teflon liner to swap over if any aluminium needs doing.

    Hi wyn, thanks for the update, I have contacted some suppliers for
    quotes on both, none even acknowledged my mail, only the guy
    I phoned got back to me, am getting a feeling I need to look elsewhere
    and at other products.
