    Hello!
    I am planning to buy a power generator. It will mainly be used to power the welding machine. The welder is a Bester 250 migomat. According to the rating plate, it needs 10KW at 250A and 7.4KW at 200A, but at the maximum setting the current reaches 180-190A according to the ammeter. Additionally, I rarely use its maximum power. I have the opportunity to buy an OTTO DG5500E generator according to the plate, its constant power is 5.5KW and max 6KW. It is diesel, so it's a plus and the price is affordable. And here my question is whether this aggregate will handle it or look for something stronger? Maybe someone had some experience with this device.
    Thanks in advance for all the answers, best regards

    In my opinion, this unit will be too "weak" for the welder to work properly. Buy a branded "stronger" aggregate from a proven manufacturer, watch out for fakes. Maybe it is worth considering reselling the welding machine and purchasing a power generator with a welding machine (in one housing).

    Maybe it will be able to try to fasten the generator, but I think that it is usually welded with a current of about 130, so these 5.5kW should pull

    So there is a solution, this unit is too weak due to the fact that a friend had it for sale, I just borrowed it for a while and tested it at 130-140A current, the welding machine turned off. You have to look for something stronger. Maybe you can advise something?

    To be able to weld freely with the maximum current, the power of the aggregate must be 75 - 100% greater than the power of the welder taken from the network (recommended by manufacturers of welding machines). On my migomat, he writes that it has a power of 5kW and writes that it can work with a generator with a minimum power of 9kW.

    Exactly, a generator with twice the power of a welding machine.
