2% Ceriated electrodes are tungsten electrodes containing about 2% cerium oxide, referred to as ceria.  The EWCe-2 electrodes were first introduced into the US market in 1987.  Several other grades of this type of electrode are commercially practical, including electrodes containing 1% ceria, but only one grade, EWCe-2, has been incorporated in this specification as having commercial significance.  The advantages of tungsten electrodes containing ceria, compared to pure tungsten, include increased ease of starting, improved arc stability, and reduced rate of vaporization or burn-off.  Unlike thoria, ceria is not a radioactive material.  These advantages increase with increased ceria content.  These electrodes operate successfully with AC or DC, either polarity.

Pure tungsten electrodes (green) contain at least 99.7% tungsten and deliver all of the benefits typically associated with tungsten – supreme conductivity, durability, and performance. Green electrodes are excellent for AC weld projects related to magnesium alloy or aluminum alloys.

2% thoriated electrodes (Red) are America’s favorite electrode for a reason. Extremely long lasting and highly durable, these electrodes are a staple in DC welding applications. These red electrodes are perfect for copper alloys, nickel alloys, titanium alloys, and non-corrosive steels.

2% ceriated electrodes (Grey) are popular due to their extreme ease of striking an arc with lower amperages, and their extraordinary performance with regard to both AC & DC welding applications. They perform best with titanium alloys, copper alloys, magnesium alloys, aluminum alloys, nickel alloys, non-corrosive steels, and low-alloyed steels.

2% lanthanated electrodes (Blue) are popular due to the relative ease of striking an arc and lower amperage required. They perform exceptionally well in both AC & DC applications, and are a popular general use electrode. Blue electrodes are highly effective for welding aluminum alloys, magnesium alloys, nickel alloys, copper alloys, titanium alloys, low-alloyed steels, and non-corrosive steels.

1.5% lanthanated tungsten (Gold) electrodes contain slightly less lanthanum than their blue counterparts and are best used in both AC & DC applications. They are best for welds with titanium alloys, copper alloys, nickel alloys, and non-corrosive steel.

Rare Earth Mix electrodes are the perfect substitute for the 2% thoriated (red) electrodes. Fast and reliable arc-striking, long lasting, and high durable, these will perform during your most difficult welding application for both AC & DC applications. Perfect for aluminum alloys, magnesium alloys, titanium alloys, nickel alloys, copper alloys, low-alloyed steels, and non-corrosive steels.

1% zirconiated (Brown) used for radiographic-quality welding where tungsten contamination must be minimized. Balls-up easily in AC applications, good arc starting and current capacity. Non-Radioactive.
