WC, WT, WL, WY... all add a single rare earth oxide to the tungsten base. WX4 uses the latest wet doping technology to simultaneously add four rare earth oxides: lanthanum, cerium, yttrium, and zirconium to the tungsten base, achieving product characteristics of burning resistance, versatility, and environmental protection. It has also obtained a national invention patent (patent number: 3293456)

Main purpose:

Multi element composite tungsten electrode WX4 is suitable for welding of all materials.
