The Thoriated Tungsten Electrodes (AWS & ISO classification EWTh-2) contain a minimum of 97.3% tungsten and 1.7%-2.2% thorium and are called 2% thoriated.
These tungsten pose a low-level radioactive hazard when exposed to the lungs via vapour or grinding dust.Will only run on DCGood arc starts with a very stable arcOperates below its melting point, which improves its lifespan significantlyNo tungsten spitting for less chance of weld contaminationMaintains a sharpened point
