Sorry for the "INPUT" snafu, I meant that the cables plug in there.

I looked at the user manual and it "Almost" matches. The AC OUTputs on
mine are 40-230 and 30-150. I cannot find the serial number, the
manual your referred to states that it is on the cover plate but does
not show where exactly. I found the "Style", it is JD-37 but I cannot
find any other numbers. I will print out this manual and go from
there.

If anyone knows where the serial number is located, please let me
know.

It should be on the data plate on the back..but they are often
gone..sigh

Most of the Thunderbolts were pretty generic, with only small
differences.
First thing you want to do is see if it actually works.

If you dont have any rod yet...take a chunk of steel and put it in the
ground clamp..and using a 16 penny nail or a piece of wire hanger from
the closet, in the rod clamp, stroke it over the chunk of steel. If
it arcs..its worth fixing up.

First I will describe it because I cannot find a picture of it on the
web to refer you to. It has a hand crank on top to adjust the amps.

Good sign - variable saturation core - nice reliable old iron and copper
technology. I'd guess you got a deal, at $20.

There are two lead inputs at the bottom right, one red, one black and
DC is painted there.

Output, not input. Power is input from the wall, and power is output to
the work being welded.

On the bottom left are three YELLOW inputs but I cannot tell what they
are for. The labels are worn and dirty. They are placed with one above
the other two like this :.

OUTputs. AC. Described below, probably, based on not really knowing
_which_ thunderbolt you have, but this one looks right.

Is there a place to get replacement lead plugs?

Welding supply, generally. Tweco or knockoffs. Or Miller, I suppose,
though those are just as likely to be Tweco.

Does anyone know where I might find a user manual for this or similar
welder that explains how to use it?

http://www.millerwelds.com/service/ownersmanuals.php

Lists eleven models of Thunderbolt manuals. Have your serial number
handy to get the correct manual for the welder you have. The "no serial
number entered" result for Thunderbolt AC/DC shows the upper of :. as
being the electrode AC for 40-225 amps, and the one below it as being
electrode for 30-150 amps, while the one to the right in that set of 3
is the work (aka ground clamp).

To the right of those is the DC set, + above -
