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 tungstens 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.
