What is the recommended use of a GTAW grinding stone?

Explanation:
Grinding stone used in GTAW is intended to shape and clean the tungsten electrode tip. The TIG arc quality and stability depend on having the correct tip geometry, so you use the grinding stone to achieve a precise point or ball end and remove any oxidation from the tungsten. This tool is specifically for tungsten electrodes, not for filler rod or other metal parts. Using it on filler rod could contaminate the filler with tungsten particles and alter weld characteristics, and grinding torch tips or other components with it can damage the equipment or disturb gas flow. So the recommended use is for tungsten only, to prepare the electrode tip for a proper TIG arc.
