Most Popular TIG Consumables

2% Thoriated (EWTh-2 / Color Code: Red )
  • 2% Thoriated tungsten is the most commonly used tungsten today. It contains 97.3% Tungsten and 1.7 - 2.2% Thorium. Thorium is radioactive, so always use with caution and follow all manufacturing warnings and instructions. Most people use 2% Thoriated tungsten because of its ease of use and low consumption rate. 2% Thoriated tungsten is only used on specific AC welding such as thin gauge aluminum and other materials .060" or less, but is great for DC welding on stainless steel, titanium, and nickel.

2% Ceriated (EWCe-2 / Color Code: Orange )
  • 2% Ceriated tungsten is made up of 97.3% Tungsten and 1.8 - 2.2% Cerium. It is most commonly used with DC welding, because 2% Ceriated tungsten performs best at low current settings. Some common applications are pipe manufacturing, thin sheet metal, orbital tube or any other projects where tiny parts need welded. Like the 2% Thoriated tungsten it is best used on stainless steels, titanium, nickel and carbon which makes it a nice alternative to the radioactive Thoriated tungsten.

1.5% Lanthanated (EWLa-1.5 / Color Code: Gold )
  • 1.5% Lanthanated tungsten contain at least 97.80% Tungsten and 1.3 - 1.7% Lanthanum, or Lanthana. It in many cases can take the place on 2% Thoriated because they have almost the same conductivity characteristics, like good arc stability, good re-ignition, slow burn-off rate and great arc starting capabilities. Another plus of using 1.5% Lanthanated tungsten is that it works well with both AC and DC welding along with both sharpened or balled points.

2% Lanthanated (EWLa-2 / Color Code: Blue )
  • 2% Lanthanated contains 97.3% Tungsten, 1.8 2.2% Lanthanum and 0.5% Other. 2% Lanthanated is a substitute for 2% Thoriated. Similar characteristics to 1.5% Lanthanated with better arc starting, arc stability and less tip erosion.

Rare Earth (EWG / Color Code: Gray )
  • Rare Earth tungsten contain an unspecified amount of rare earth oxides, or different combinations of oxides. Manufacturers are required to identify these oxides and their percentages on each package. Depending on the oxides added Rare Earth tungsten can give you a variety of characteristics such as, longer life than Thoriated, higher current with same sized tungsten and stable arc in both AC and DC welding.

Zirconiated (EWZr-1 / Color Code: Brown )
  • Zirconiated tungsten contains 98.6% Tungsten, 0.7 0.9% Zirconium and 0.5% Other. It balls up easily in AC applications. Handles higher current with less splitting. Improved arc starts and arc stability. Offers minimal tungsten contamination.
