Actually Greg you know that (I know that you know) it depense on balance does the tip get rounded or not. I too like to use green on aluminium and do often start with sharpen tip but it'll get ball on it because I like to weld with some of the heat getting to my tungsten. Of course I do take a couple of practise passes to scrap piece get tip ready to actually job in hand.

I love that quote....I had to rewind to make sure I heard the transmission correct when they played it. Got to love Kimi. Bummer Lotus isn't treating him too well.

Typing on an iPad so short reply. If you start with a pointed tungsten on an inverter machine and end up balled. Then your settings are wrong and your tungsten is going into the weld. NOT GOOD.

Well, I left disregard the "inverter" part. Dont know about them but like mine normal "pro" machine..
