XTRweldTM E3TM Rare Earth Tungsten Electrodes are a high-performance, non-radioactive alternative to thoriated tungsten. Composed of a proprietary blend of rare earth oxides (including lanthanum, cerium, and yttrium), E3 electrodes deliver excellent arc starts, exceptional arc stability, and reduced electrode wearacross both AC and DC welding applications. These electrodes are ground and ready to weld right out of the package, with minimal burn-off and contamination.

• Non-radioactive alternative to thoriated tungsten
• Excellent arc starting and stability across AC & DC currents
• Suitable for all materials: steel, stainless, aluminum, nickel alloys & titanium
• Ground finish ready to use, no prep required
• Ideal for manual, automated, or robotic TIG welding
