SD Generator Info needed

[matt]

Has anyone had experience in the SD brother of the ST generator series?

This is the dual use welding/AC generating model.

How does the unit make the DC for the welding? A whole seperate winding or via a rectifier?
If it has seperate DC windings, I wonder if we can make it a starter like the Start-o-Matic? 

Interesting possibilities with this unit if it is wired the way we need.
Though I suppose if there was anything in this someone would have already reported as such in this forum.

Any ideas?

thanks,
Matt

Hi Sailawayrb, Thanks for the link. I have seen that before. Unfortunately it does not say much if anything about the internals.

Looks like it will only run a small current at the AC feed while in welding mode.
I read there is enough for  "small scale illumination simaltaneously".

Are these a real DC Generator inside as well as a real AC Alternator?

Could be an AC welder.

they use a pair of stud mounted diodes  in a full wave rectifier.

therefore no commutator and no simple way to make one motor with DC current.

Thanks Bob G for the info. Thought as much.

Back to the old drawing board.
