Thanks for that, much appreciated. In the pic I've attached, numbered 1,2 & 3 my plan is to #1 renew the pot, #2 resolder / replace the wires to the pot and #3 clean the contacts in the relay?Have good look at relay that is switching on main transformer. I was fixing one Electra Beckum recently, same symptoms as yours. Turned out there was problem with burnt contacts of main contractor. When tested, welder was giving proper voltages readings but there was not enough power to burn wire properly. Also as stated above redo all high current connections , you need to get rid of any oxide and burns.
