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.
