I have a dedicated tungsten grinder....
This is the model I own -- but these little things ARE as you know - expensive!

A couple of things....
#1) Tungsten dust ain't good for ya!
#2) The shape and quality of your tungsten IS important.
Be sure you're grinding properly -- and on a dedicated wheel that isn't contaminated. If you can't afford a dedicated tungsten grinder....pick up a cheap bench grinder at Harbor Freight or something of that quality and use it
only for tungsten work.
There are tons of educational videos on this subject on YouTube... takes only a couple minutes and maybe you'll spot something you are or aren't doing.
Remember --
INVERTER TIG welding - YOU DO NOT ball the tungsten for aluminum... you point it like everything else you're doing.
I got a good laugh at this scenario... because as many people discover - the initial purchase of equipment is the "cheap part".... it's all the other stuff you need to make PRO quality parts! I own an inexpensive JET "mill/drill".... I've spent 3 times the original purchase amount on cutters and collets and vises and indexers...
