Hi Jpcook13!
If I remember correctly, that's an equivalent to a Miller AEA, or AEAD 200, or 200E, or 200L, or 200 LE... Here's an owner's manual of the Miller equivalent:
http://www.millerwelds.com/om/o410h_mil.pdfNow I don't know if this manual covers your particular model # but, if you look at the serial number and go to this link @ Miller, you should be able to narrow it down closer to the equipment you have... Here's the link:
http://www.millerwelds.com/service/ownersmanuals.phpScroll down the list to find the model equivalent by opening each .pdf, or enter the serial number to find the appropriate matching owner's manual.
KSellon might also be able to help since she has one up for sale by "Steve" @ their website, and she really knows her stuff with respect to not only engine drive welding equipment of many different brands, but also of all types of welding equipment troubleshooting and repair in general... Top notch IMHO because I've done my fair share of equipment repairs & servicing over the years, and did it for a living many moons ago so, I can say that they really know their stuff!!! ;) Here's their link:

I think that if you keep an open mind, you'll find it to be a hilarious spoof on farm welding so, enjoy!!! :) :) :)
Respectfully,
Henry
