I am new to Tig also. Have about 5 hours under my belt. Self taught in Mig, and now Tig. Beads look good to me. The only thing I was told(and I talk to whom ever will listen on Tig) is that the point on your Tungsten depends on the quality of the weld bead. The sharper the Tungsten, the better the bead. I am still learning.
