• Compound tungsten electrode is also known as three elements of rare earth containing 1.5% lanthana 0.8%zirconia and 0.8% yttria.
• It is a non -radiation material. It is good to balance the electron mobility and evaporation rates making tungsten electron to maximize their performances.
• For compound tungsten electrode it's easy to start and restart arc. If the welding cycle more than 15 minutes its life will be longer.
• Compound tungsten electrode is better than others in tip burning.As the mixture of three kinds of oxidees in electrode.
• It is strict with the production process and the cost of production is more expensive.
