need help with esab mig 2e

[tjsr19]

I got a esab mig 2e for a case of beer. The wires are cut but it has the voltage sensing box as well. I can not find any info on this wire feeder. I would like to fix it up but I cant even find a product manual. Please help.
I have used many welders with wire feeders but for mantince I have never done anything more than change out the spool.
Thank you
