That last post the spell check got me good!anyway this is my piece of sandpaper I use,I got the idea from an old timer who did power plant welding,maybe it's in my head,but it works for me!

Seems the great tungsten death is all over the map,I use alot of 2% lanthinated, I really like E3,also Ceriated does pretty well,but I will say,once I figured out how to grind them right slot of my problems went away,especially on aluminum,I found that after grinding them,if I rubbed then back in forth in a straight line while turning them on a sheet of 400 grit sand paper they seemed to last longer,and weld better

I have recently taken to using my polishing motor and some Tripoli to polish tungsten. Not a huge difference but noticeable. Over 150 amps you can grind any way you want and it works.
