WP018X7 - Weldcraft EWP Green Pure Tungsten Electrodes 1/8" (10-Pack)

Weldcraft WP018X7 Pure Tungsten Electrodes (Green)

The Weldcraft WP018X7 Pure Tungsten Electrodes are a premium choice for TIG welding professionals requiring reliable performance in Alternating Current (AC) applications. Identified by their distinctive green color code, these electrodes are manufactured from 99.5% pure tungsten, making them the most unalloyed form of tungsten electrode available on the market. This high level of purity is specifically engineered to provide excellent arc stability when welding non-ferrous metals, particularly aluminum and magnesium alloys. Unlike alloyed tungsten variants that are designed to maintain a sharp point, pure tungsten is celebrated for its ability to form a clean, balled end when heated. This balled tip geometry is crucial for AC welding as it helps to spread the arc over a wider area, improving cleaning action and heat dissipation.

These electrodes are classified under the AWS standard as EWP (or simply WP). They are non-radioactive, eliminating the safety concerns associated with thoriated tungsten, making them a safer option for welders in confined spaces or those adhering to strict environmental safety protocols. The WP018X7 model features a 1/8-inch (3.2mm) diameter and a standard 7-inch length, suitable for a wide range of TIG torches and collet bodies. While they excel in AC applications using transformer-based constant current power sources, they are not recommended for Direct Current (DC) welding, as they do not maintain a point well and are prone to spitting at higher amperages in DC modes. However, within their intended scope of AC sine wave or square wave welding, they offer consistent, contamination-free starts and a stable arc that is essential for precision aluminum fabrication.

Each package contains 10 genuine Weldcraft electrodes, ensuring you have an ample supply for production work. Whether you are repairing magnesium castings or fabricating aluminum structures, the Weldcraft Pure Tungsten electrode remains the traditional and effective choice for achieving high-quality welds with balanced or unbalanced AC waveforms.
