fun4now asked a good question. how do you keep a steady arc if there are ridges all down the tip?
I use only ss brushes and as far as the tungsten goes I have never had a problem. Where I worked everyone ground their tungsten the same way and I don't recall anyone complaining of tungsten sputtering or the arc wandering. I still tig in my garage today and grind my tungsten the same way. I mostly tig because wheelchairs and sparks dont seem to get along but still stick weld from time to time.
