Here is a close-up of the guts of my welder. The two big wires on the left are positive and negative from the load center. Positive connects to the (lower) positive post of the capacitor and goes on to the ground clamp. Negative goes to the inductor through the other side and then connects to the negative post of the capacitor and on up the cables to the gun. The two wires from the secondary coil of the transformer are detached and taped off. I also removed the resistors that I had to drain the capacitor. I am now back to a hot tip gun, but I think that helps to kick start the arc.
