Deep down I already know the answer to this is NO, but on the off

I have an old Lincoln "buzz box" welder with a dead cooling fan. Parts
to fix will run $76 and change.

I also have a Radio Shack 120V muffin fan #273-241 that's the right
size. $25 is much better than $75.

The original fan is 220V. I can wire up the new fan as 120V, but what
would really be great is if I could wire it up as 240V. That'd move a
whole lot more air.

Will the fan be able to deal with the higher voltage?

Radio Shack 273-241 is rated at 120V, 22W (approx 180mA)

You could wire a 4uF (or close) MKP ** MOTOR RUN ** cap in series with the
fan. At 60 Hz this should give about 660 ohms series reactance which
should drop 120V at 180mA if my arithmetic is correct.
