Sharpening a Tungsten
Sharpening a tungsten is very important for a nice fine arc strike. There are auto sharpeners to place the perfect
sharpening point on your tungsten or you can simply use a grinding wheel to sharpen your tungsten. Remember,
after sharpening to a pencil point, you want to flatten the bottom for a good arc.
