New .020" pure tungsten electrodes green 7" long 10PCS
This is New .020" PURE Tungsten Electrodes (10pc. total) by SEVEN inch long, Color Code Green.
Pure Tungsten, Green, AWS Class EWP, AC welding applications. Least expensive of all electrodes. Applications: aluminum and magnesium alloys.
EPP Electrode Classification (Green Stripe).
Pure tungsten electrodes (EWP) contain a minimum of 99.5 percent tungsten, with no intentional alloying elements. The current-carrying capacity of pure tungsten electrodes is lower than that of the alloyed electrodes. Pure tungsten electrodes are used mainly with AC for welding aluminum and magnesium alloys. The tip of the EWP electrode maintains a clean, balled end, which provides good arc stability. They may also be used with DC, but they do not provide the arc initiation and arc stability characteristics of thoriated, Ceriated, or Lanthanated electrodes.
Like Zirconiated Tungsten, this tungsten is also only used for AC welding and there are better alternatives available.
