welder recommendations

Well I picked up that old black Hobart handler welder last weekend. Haven't done much with it yet, I think it's one of the original Hobart handler welders....
Before the miller buyout. If I'm guessing right looking at the serial number it's from 1988.
There's one(used) just like it on eBay for 4x what I paid, similar to what it would have cost me closer to home. It's got a pretty big roll of flux core wire on it now, and I see some rust within the spool, I did make a few sparks with it at the seller's home, before I paid for it.... But that's all so far. I did find a gas bottle kit for it, but I'll probably unwind and throw away a couple of layers of the existing flux core wire that's there, get into the fresh stuff further in and see how it does.
Model number of the one I got is a 6969A, (there was also a 6969 without the "A") don't know what difference that made.
Built in troy Ohio, definitely not Chinese.
Part of me wishes I had this unit earlier in my truck build, don't know if it would have helped in the areas that gave me fits. It's only 90A with 4 power levels on the switch. Id like to at least find a manual for it.
I'm as done with the cab as I'm gonna go with it body and paint wise. Now to borrow my neighbors bigger trailer, go p/u the bed and other panels and hike it to the blaster then the paint shop
