WR Compound Electrode
The composite tungsten electrode balances the mobility and evaporation rate of internal electrons, maximizing the performance of the tungsten electrode and reducing the electronic work function of electrons. It is easy to start and repeat arcs, and if the welding cycle is greater than 15 minutes, its service life will be longer. The material is the alternative to WT20 as green products
Application: Stainless steels, carbon steel, Nickel, Titanium, Copper, Magnesium, Aluminium and its alloys..
