WTPURE156 XTRweld Pure Tungsten Electrode, 5/32, Green, 10 Piece, 7 Inch L

SKU: XTRWTPURE156

Tungsten is a rare metallic element used for manufacturing gas tungsten arc welding (GTAW) electrodes. The GTAW process relies on tungsten's hardness and high-temperature resistance to carry the welding current to the arc. Tungsten has the highest melting point of any metal, 3,410 degrees Celsius.

APPLICATIONS

    Pure tungsten electrodes contain 99.50% tungsten, have the highest consumption rate of all electrodes. These electrodes form a clean, “balled” tip when heated and provide great arc stability for AC welding with a balanced wave. Pure tungsten also provides good arc stability for AC sine wave welding, especially on aluminum and magnesium. It is not typically used for DC welding because it does not provide the strong arc starts associated with thoriated or ceriated electrodes.
