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 " magic 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???
