About MELTSTAR TIG Welding Cerium Tungsten Electrode
The 2% ceriated tungsten electrode (AWS classification EWCe-2) contains a minimum of 97.30% tungsten and 1.80 - 2.20% of yttrium These electrodes have the best DC welding performance at low current settings, but can be proficient with AC or DC welding processes With its outstanding arcing properties, low current amperage, and thulium tungsten, it has become very popular in applications such as orbital tubes, pipe manufacturing, thin sheet metal work, and welding of small, precision parts. It is best suited for welding carbon steels and stainless steels, nickel alloys and titanium, making it a clear alternative to 2% niobium electrodes. Compared with WT20, it is non-radioactive material The electron emission capability is higher than that of neodymium tungsten, the arc voltage is low, and the arc is stable Positive polarity, allowable current density is higher than thorium-tungsten 5%-8%
