WT20 - red

The ignition-friendly one

  • Colour: red
  • For carbon steel, stainless steels, silicon bronze, copper, bronze, titanium.
  • Composition: W + 2% thorium
  • Due to its very good ignition properties, this is a widely used type of electrode, which is, however, increasingly the subject of discussion due to its 2% radioactive thorium content.
  • This type can now be successfully replaced by radiation-free electrodes, such as Lymox® or WL15.
