I know its a drive Alex but you are welcome to my welder anytime mostly. I use a lanthanated tungsten (Silver paint) with high power AL I tend to vaporize pure tungsten faster. Once again see the dirty hack. part. RFO I have always been told to use a stainless brush as well what do you recommend. Let me dig around Alex I have a handy chart for aluminum and filler rod selection based on alloy.
I wish I had some pictures but on old race car builder I knew built a really cool fixture for welding round things. It was a flywheel and starter off of a car hooked to a speed control with a lathe chuck mounted to the flywheel. We would set the speed and weld full round without stopping.
