Weldporn TIG Welding Electrodes - Pure Tungsten (Green / EWP)

Weldporn Pure Welding Tungstens (EWP) are unalloyed tungsten electrodes (99.5% tungsten minimum) and are non-radioactive. These Pure Tungsten electrodes are color coded Green for easy identification. Pure Tungsten Electrodes current-carrying capacity is lower than those of other tungsten electrodes. They provide good stability when used with AC, either balanced wave or continuously high frequency stabilized. They may be used with DC and also with either Argon or Helium, or a combination of both, as a shielding gas. They maintain a clean, balled end, which is preferred for aluminum and magnesium welding. These electrodes have reasonably good resistance to contamination of the weld metal by the electrode, although the oxide containing electrodes are superior in this respect. EWP electrodes are generally used on less critical applications, except for welding Aluminum and Magnesium. The lower cost EWP electrodes can be used for less critical applications where some tungsten contamination of welds is acceptable.
