By my count you switched the breaker back on at least three times.
It's there, and it tripped, for a reason.

And you saw arcing. But still you switched the breaker back on.

At some point doesn't it make sense to call a professional? Turning a
tripped breaker back on repeatedly is somewhat defeating the purpose
of a circuit breaker, which is to prevent whatever is causing it to
trip from continuing to cause damage. Circuit breakers are wonderful
but they're not perfect.

Since there may now be more than one problem, I think it makes sense
to call someone who knows what he's doing.
