Grinding the tip when it is contaminated may not remove all of the contamination and will deposit the contamination on the grinding wheel, only to be picked up again in future grinding. Because tungsten is a very hard material, proper cutting involves using a diamond cutting wheel for consistent, clean cuts. Many welders cut theirtungsten.

Because tungsten is a very hard material, proper cutting involves using a diamond cutting wheel for consistent, clean cuts. Many welders cut theirMost of that money spent on tungsten electrodes is wasted during the grinding process, for multiple reasons 1. Tungsten electrodes get thrown out when they get an average of 50 mm 2. The grinding lacks precision and therefore requires multiple attempts 3. The tip of the electrode is cut before it is being ground again. You may ask your selfGrinding Tungsten Electrodes with Diamond Wheels coarser the diamond grit, the faster the grind. For a smooth finish, grind with a 300grit wheel, the standard on most dry grinders. For smalldiameter tungsten grinding, 116 1.6 mm or below, use a finer grit wheel for that critical smooth
