WLa 20 BLUE

WLa 20 BLUE

This tungsten electrode is mainly used for welding unalloyed and high-alloy steels, aluminum, titanium, copper and magnesium alloys. Its doping element, lanthanum oxide, makes it suitable for direct current as well as alternating current welding, just like the E3®. The golden TIG welding electrode is also used in micro-plasma welding.

    • Colour coding with lanthanum oxide:
      • Blue = WLa 20 – with 1.7 to 2.2 % lanthanum oxide
Direct current minus pole +++
