ok, so considering this one:

I would look at this and say that since there's no electronics, I can
wire up any old 220 line (assuming the line had the appropriate
current rating). Does that sound right? It looks to me like it
combines the two 110 lines right at the screw terminal where the power
comes in.

In the US, two separate 110 legs are delivered to
the house. ?When we
need 220, the magic of constructive interference is applied, and we
get 220. ?The 220 is delivered to the appliance as two separate 110
wires, a neutral wire, and sometimes a separate ground wire for
safety.
Some things don't have a separate neutral line, in which case they don't
require 120V power.
Because of this arrangement, sometimes appliances
(I believe, maybe
I'm wrong) will pull 110 from one of the legs to power electronics in
the appliance.
Yes, some do that. ?You can always wire in a 240V to 120V step-down
transformer to run the extra bits. ?It's rarely much power (timers,
clocks, etc), so you probably could get away with a 100W or so step-down
transformer, which should be pretty cheap.
