Jerry,
The CB rating needs to be applicable to the wire gauge as well, you can't
just throw a 50amp brealer on 16 ga wire, the wire overheats and melts the
insulation before the breaker trips.
Take a look at the NEC (should be a copy at the library), and get the info
with wire size vs. current rating.
With that said, 40 amp CP should be sufficient for a180-200 amp buzz box,
but you really need to verify by the input rating of the unit (should be a
tag with s/n, voltage and current on it).
You probably have an AC welder, hook the ground to the frame, the "work" or
load to the tap that shows the current rating.
With a 110v buzzbox, proably 1/16th rod. Not sure of the type, I usually
grab what my Dad tells me to use:)
