Ah sorry about that. I made some pictures a couple of days before and posted them on a different forum. By then, I had "s(h)orted" (hehe) the problem. Crappy pictures inbound! In the meantime I contacted Weldequip to see if they can do anything for me.
On the first pic, the top right corner has the 3 power inputs. Just under there, the 4 solder holes, is where the relay goes. The 2 isolated solder points to the left of that is where the transformer hooks up.
