I was looking at a 2005 model 350P with about 300 hours on it and I'm assuming 10,004 arc strikes on it.(It was only registering 4 so I assumed it turned over). Again, assuming that it was not used in a heavy plate fab shop being ran near max every day, what are the hour and arc strike "numbers" when you should just not even consider the machine and walk away from it?
By the way, I could probably get the machine for about $1,400.00.

Also, when you would turn it on and it would power up, it would buzz very, very loudly. Much louder than the new 350P that I have. Is that an indicator of something???
