Grinding tungsten ...... the best part of learning Tig welding. The profile on the tip has much to do with arc wonder and the heating area of the puddle.
As mentioned using a bench grinder to sharpen the tungsten will put a grove in the wheel real fast, and will/can contaminate the electrode with other metal particles in the stone that have been left behind.
Here are some things I learned and maybe helpful or at least food for thought. Diamond wheels are the best bang for the buck. I bought a HF chain saw chain sharpener, the diamond wheel is 10 bucks to replace. The sharpener is about 45 bucks, tungsten sharpeners cost ridiculous prices @ 250 and north. Look like a Dremel tool with a diamond wheel the size of the dremel cut off disk. Bought one used it for a short while sold it, found zero advantage for that purpose built tool.
Below, my answer for grinding electrodes quickly, allows me to experiment with the angle and length the profile, using a drill to turn the electrode. You will read when grinding the electrode you want the grind marks to have a linear pattern down too the tip, if they go around the arc will wonder. So low and slow RPMs of the drill.
Have no fear you are going to learn how to grind the electrode, the only other thought to pass. Tig is exactly the same a O A, or gas welding, if you have that experience you will pick up the Tig process very quickly.
