Products Specification WC20 Tig Electrode contains a nominal 2wc-% of cerium oxide (CeO2). Ceriated is different from thoriated as it is not a radioactive material. WC20 Tig Electrode has good starting arc performance, low melting rate, long welding life, it is mainly used for welding under the condition of low current. Cerium-Tungsten Electrode have good starting arc performance under the condition of low current. The arc current is low, therefore the electrodes can be used for welding of pipe, stainless and fine parts. Cerium-Tungsten is the first choice for replacing thoriated tungsten electrode under the condition of low DC; Cerium-Tungsten Electrode has the following merit compared to the thorium tungsten electrode: (1) Non- radiativity; (2) Low melting rate; (3)Long welding life; (4) Good gets up the arc. Product Description Cerium Tungsten Electrode are added in the rare-earth cerium oxide powder metallurgy and rolling mill, after throwing the production process from the tungsten electrode PRODUCTS are produced in our country the first non-radioactive tungsten electrode products, the features of the product are at low current conditions have good starting arc performance, a smaller-dimensional arc current. Therefore, it commonly used in the pipe, stainless steel products and welding of small precision parts. At low current DC or electrode diameter under the conditions at 2.0mm below cerium thorium tungsten electrode tungsten electrodes are the preferred alternatives.
