Big Blue 400d generator upgrade?

[bode]

Good evening everyone. I am looking for info on a recently new to me welder/generator in the title.Serial # KF973187 was purchased to run our Ranch repairs and misc. generator work. My mistake was that this machine is a 3kw generator and we need more for emergency power. The manual downloaded says there is an optional auxiliary power plant for this machine that can power 12/10kw.Does anyone know what is involved in this upgrade and is it economically feasible?Thanks much.

Big Blue 400d generator upgrade?

I'd call Miller to find out for sure. But on my JJ Big 40 (1988 I think) it is not a field service item.
As manual stated & my LWS said not possible to change.
Let us know if find different.

Thanks for the reply, have two opinions that are the same as yours. Just got this back from Miller this morning:"In regards to your question on the Big Blue 400 auxiliary power capabilities. This machine is only able to produce 3000 watts of aux power. It was only intended to operate small tools and accessories to support the welding applications. The optional KVA package that this machine was capable of having was a factory only option that had to be installed at the time of the machine build as it was an entirely different generator. Unfortunately there is nothing that I can do to help you get more power out of this machine. The windings in the generator are not there to support it.Let us know if you have any further questions."Was hoping someone had a DIY or shade tree approach. Its a great machine but looks like I will be sending it down the road. Thanks again gnforge!

Yep that's what I thought.
If the price was good on welder. There a super welder. Mine did hv the CV pkg which I wanted. It runs a wire feeder all day long with power to spare. I just bought a cheaper generator for power backup. But all things considered one unit may suit u better.
Good luck.

Have to change the $$$$ rotor for more power. Changing the rotor is quite the hassle, i might add....

I purchased it right, big attraction was the deutz diesel. It is a welding SOB! Might look at another generator. Thanks again. FMI, what would a ball park price be to put another generator in this thing to make it do what we want?

Your rotor alone lists at $2081.84 at miller4less.

Wow, thanks. Started welding with the machine, sure is much smoother than what we have used in the past. Thanks to everyone.
