Wow, I hadn't seen one of those in 20 years. I personally used to weld those center bars when I was in high school. I've got no idea of the performance numbers of that unit, and I don't even know where to start. We've had 2 operating system changes since then and finding hard copy of that would be the proverbial needle in the haystack.
It's in GREAT shape and if it works for your needs, those are all the performance numbers you need.
