So I went out and looked, it is a weld-pak 155, the manual from Lincoln was from 2010.
I'll obviously need to order the instructional "video"

Bummer it's missing the side panel, it has specs/welder settings on it. It also looks to be missing the pieces to hold the wire spool in place(wing nut and holder). The good thing is it has the mig option which is the gas hookup and gas gun/wire. There are 3 smaller spools of shielded wire(flux-core), .025, .030, and .035. In the manual it says it was set up for .035 from the factory and to run smaller diameter you need to have different tips and the feed roll can be flipped to push the smaller wire and there is a fine adjustment there.
Some of the basic specs.
