None other than America Alloy (AA) provides the AA grade Tungsten! Welder's choice, tested good and reliable quality.

You are on the page of America Alloy(AA) 10pcs GTAW / TIG Welding Tungsten Electrodes 2% Lanthanated EWLa-2 / WL20 Tungsten Electrode(Sky Blue)

America Alloy(AA) 10pcs GTAW / TIG Welding Tungsten Electrodes 2% Lanthanated EWLa-2 / WL20 Tungsten Electrode(Sky Blue) is good replacement for WT20 radioactive tungsten rods.

The lanthanated tungsten electrodes are becoming more popular in the circle of welding in the world soon after they were developed, because of their good welding performance. The electric conductivity of lanthanated tungsten electrode is most closed to that of 2% thoriated Tungsten electrodes, but not radioactive. Welders can easily replace thoriated tungsten electrodes with lanthanated tungsten electrodes at either AC or DC and not have to make any welding program changes.

Features:

• Handle more amperage then any other alloy
• Can be used on all types of machines
• Has the lowest breakdown voltage (meaning easiest to start an arc)
