Pure tungsten (green): Used for AC welding of aluminum and magnesium alloys as well as non-corrosive materials.
2. 2% thoriated tungsten (red): Used for DC welding and has a higher current carrying capacity, making it suitable for welding carbon and stainless steel.
3. 2% ceriated tungsten (orange): Used for both AC and DC welding and is known for its ability to maintain a stable arc in low current settings.
4. 1.5% lanthanated tungsten (gold): Used for both AC and DC welding and is similar to 2% ceriated tungsten, but with improved arc starting characteristics.
5. 0.8% zirconiated tungsten (white): Used for both AC and DC welding, especially for welding aluminum and magnesium alloys at higher amperages.
6. Rare earth tungsten (light blue): Used for both AC and DC welding and is known for its ability to maintain a stable arc over a wide range of current levels.
