Perhaps start in from the end to heat the job then come back to the end and go over your cold start , been a while since i've done lots of ally welding but this might help other than a TIG.

Im not sure if that would overheat doing it that way, but i will give it a try. I have found that it is still penetrating and looks ok when its ground. I am going to be covering my footboxes with Al so the welds will be ground flat any way.
Thanks for the advice everyone.
