T187GL - CK Worldwide 1/8" Gold Tungsten Electrodes (10-Pack)

Premium Non-Radioactive TIG Welding Electrodes

The CK Worldwide T187GL 1.5% Lanthanated Tungsten Electrode is a high-performance consumable designed to meet the rigorous demands of modern TIG welding. Identified by its industry-standard Gold color code, this electrode is composed of 97.8% tungsten and approximately 1.5% lanthanum oxide (EWLa-1.5). It serves as a premier, non-radioactive alternative to the traditional 2% Thoriated (Red) tungsten, offering welders a safer working environment without sacrificing performance characteristics. This 10-pack of 1/8" (3.2mm) diameter electrodes, each 7 inches in length, provides exceptional value for professional fabricators and industrial maintenance teams.

Optimized for Direct Current Applications

While versatile enough for various setups, the T187GL is specifically engineered to excel in Direct Current (DC) welding. It is fully compatible with both modern inverter-based machines and traditional transformer constant current power sources. Welders will appreciate the electrode's ability to handle a wide amperage range while maintaining a focused and stable arc. The addition of lanthanum oxide significantly improves arc starting and re-ignition capabilities, making it a favorite for tacking operations and repetitive welding tasks where reliable ignition is critical.

Superior Material Compatibility

This 1.5% Lanthanated tungsten is the ideal choice for welding a broad spectrum of materials. It performs exceptionally well on carbon steel, stainless steel, nickel alloys, copper alloys, and titanium alloys. Its low erosion rate means the tip retains its geometry for longer periods, reducing the frequency of grinding and extending the overall life of the electrode. Unlike some other tungsten types, the T187GL resists spitting, ensuring a clean weld puddle and reducing the risk of tungsten inclusion defects in high-quality welds.

Key Benefits for the Professional

Switching to CK Worldwide's Lanthanated tungsten offers a blend of safety and efficiency. The elimination of radioactive thorium makes it safer to grind and handle, simplifying safety compliance in the workshop. Simultaneously, the electrode's durability under high-heat conditions ensures consistent penetration and bead appearance. Whether you are fabricating aerospace components from titanium or performing maintenance on stainless steel piping, the T187GL delivers the reliability required for X-ray quality welds.
