Which color banded tungsten you going to use?

Need to form a nice round ball on the end of the tungsten. If I remember right. DC straight will do it. If it's a narrow bead. A taper tungsten with a flat point will work.

At the end of the weld. Move the tungsten off center of the weld puddle to prevent the puddle center from getting a crack in it before you stop the arc.
