T0407GC2 - CK Worldwide 2% Ceriated Tungsten .040" x 7" (Grey) - 10 Pack

Precision TIG Welding with CK Worldwide Ceriated Tungsten

The CK Worldwide T0407GC2 is a premium 2% Ceriated Tungsten Electrode, identified by its industry-standard grey color code. Manufactured to AWS A5.12M/A5.12:2009 specifications, this electrode falls under the EWCe-2 (or WC20) classification. It is composed of 97.3% tungsten and 1.8% to 2.2% cerium oxide. Unlike Thoriated tungsten, Ceriated electrodes are non-radioactive, making them a safer choice for welders concerned with the health risks associated with radioactive dust during grinding.

This .040" (1.0mm) diameter electrode is specifically engineered for versatility and stability. It excels in both Alternating Current (AC) and Direct Current (DC) applications, compatible with modern inverter power sources as well as traditional transformer machines. The addition of cerium oxide improves the electrode's capacity to start the arc at low amperages, maintaining a stable arc without spitting. This makes it a preferred choice for welding thin materials where heat input control is critical.

The T0407GC2 features a ground finish, ensuring precise dimensional accuracy and consistent electrical conductivity. It exhibits a low erosion rate, which translates to a longer service life and fewer regrinds compared to pure tungsten. It is highly effective for welding a broad spectrum of materials, including carbon steel, stainless steel, nickel alloys, titanium alloys, and even aluminum and magnesium alloys in AC mode.

Packaged in a set of 10, these 7-inch electrodes provide professional welders with a reliable, high-performance consumable that meets the rigorous demands of aerospace, petrochemical, and semiconductor fabrication environments.
