Tungsten Electrode Standard Diameters

Diameter (mm)	Tolerance (mm)	Diameters of tungsten electrode can be tested by vernier caliper, which includes inner diameter and outer diameter. For solid tungsten electrode, the diameter is outer one. The key caliper is used mm as its unit with grids of 10, 20, and 50. Besides the standard diameters, tungsten electrode diameter can be customized, so is the tolerance.
