Advantages of these 2% Tungsten Electrodes compared to EWP or Pure Tungsten are the addition of 2% cerium oxide in place of thorium. They are non-radioactive, easier to start than pure tungsten and have improved ARC stability and reduced rate of burn-off or vaporization. Electrodes can be used on AC or DC in either polarity. 

Principally used on: Carbon steel, Stainless Steel, Nickel, Nickel Alloys, Titanium, Copper Alloys
