On a different subject, can you some time go over when to use and not use DC/helium for heavy alum without preheat. I have found this an excellent way to weld thick alum with little or no preheat, but the joint needs to be cleaned really well, and use only 4043 rod.


this is Jody chiming in...I did some DC aluminum welding a few days ago. I am waiting on a good job to use it on before I shoot a video
