For the Mopar and Hobart collector who must have everything.

I read the description as having both 400 Hz, (obviously AC), and two voltages of DC. That damned comma in there, doncha know??

Think of a standard car alternator, which produces alternating voltage at a frequency proportional to the rpm of the alternator. Pass this alternating voltage thru some diodes and you get a DC voltage with ripple component. At slow speed the ripple is large, at high speed it's fairly low.
This big generator will run at governed speed such that the output voltage alternates at 400 cycles. Then the output is chopped to DC with a small amount of ripple. The alternator will have two voltage taps, one at 28V and the other at 277V. The max current output times the voltage for each tap when added together will be 72,000 watts. This is a big MF generator and needs to treated with great respect or it will bite your ***!!!

Not being well versed in welders... would this make for a good stick welder, or just an aviation generator? IDK where you could use this thing, other than as a display piece... Where else would the 400Hz be applicable?

You drive it around your cattle ranch, making repairs wherever the herd has broken the fence. Don't you remember these guys using one just like it?

That works for me, but the description of the generator says 400 Hz DC. So how can it be both? If it has a cycle it has to be AC, not counting dirty DC.

Use a full wave bridged rectifier with a capacitor to smooth hed lumps

my great uncles yard welder , now mine . he put the axle with mech brakes and leaf springs under it , so it could be tow'd .

this hobart is an old meat cutting band saw , 220a/c 3 phase , no chrysler power plant .

yes , i got the butcher block from the same place , it solid tunge n groove birch cutting block . just trying it on for fit , lol .
