Pure Tungsten Welding Electrodes. The EWP electrodes are unalloyed tungsten electrodes (99.5 percent tungsten minimum). Their current-carrying capacity is lower than that of other electrodes. They provide good stability when used with alternating current, either balanced wave or continuously high frequency stabilized.
