A-EWCe-2 (select size from drop down menu above) Amplify™ Brand High-performance, 2% Ceriated Tungsten Electrodes. Description: Good for low amperage, DC orbital tube, pipe, thin sheet, and small part applications, this non-radioactive formula offers low current capacity, low arc ignition, and good arc stability.
Lanthanated tungsten maintains a sharpened point well, which is an advantage for welding steel and stainless steel on DC or AC from square wave power sources. Unlike thoriated tungsten, these electrodes are suitable for AC welding and, like ceriated electrodes, allow the arc to be started and maintained at lower voltages.
Blue: 2% lanthanated (AC and DC) Gold 1.5 lanthanated (AC and DC) Red: 2% thoriated (DC only) Green: pure tungsten (DC only) Don’t use green on the AC side since pure tungsten will ball up, especially if you’re using an inverter. Some welders have a particular favorite kind of tungsten. They may swear by thoriated or pure tungsten.
The most commonly used tungsten in the United States. This tungsten is used primarily in DC welding. It has a low work function and provides a high load and amperage capability. The health safety issue of 2% Thoriated tungsten has recently raised concerns regarding inhalation and disposal of the Thorium. Wolfram & Standard material only.
