Hmmm... I wholeheartedly agree with the above posts. The area is still depressed, most of the mills have closed, there is still a lot of violent crime, and yes, you should most definitely have a job lined up before moving to Youngstown or even nearby Pittsburgh or Cleveland.
Those are the negatives. The positives would be low cost of living, good schools, access to cultural institutions and events, many safe and affordable communities, etc... There is still enough manufacturing left in "the Valley" that finding a job as a welder may not be an impossibility.
Here are a couple of links that you could look through to browse job openings in the area:
