I think it's odd that the cold shut is on the same seam. So, I think maybe your forge isn't quite getting hot enough and this is causing the problem. I've noticed that as time went on my forge would do that, the flux and just general use would degrade the insulation. Once I got in and relined it the problem was solved. In my experience when cable fails to weld the first time, for some reason getting it to weld up a second time is much more difficult. I believe that since you are in the lower range on the welding temp that second chance problem comes in play.
Putting the ground charcoal may help since a higher carbon content will lower welding temps.
Keep us up to date on the progress.
