Xtrweld WTPURE250 Pure Tungsten Electrode 1/4 Inch 5 Pack

Product Description

The XTRWELD WTPURE250 is a pure tungsten GTAW electrode designed for gas tungsten arc welding applications. Each electrode measures 1/4 inch in diameter and 7 inches in length, and is sold in a 5-piece pack. Manufactured with a minimum 99.50% tungsten content, this electrode forms a balled tip when heated, delivering stable arc performance during AC welding. Tungsten is chosen for GTAW work because of its exceptional hardness and high-temperature resistance, allowing it to carry welding current to the arc without melting down under normal operating conditions. The green color coding identifies this as a pure tungsten electrode at a glance on the job.

The WTPURE250 is suited for AC welding with balanced wave and AC sine wave processes, making it a common choice for welding aluminum and magnesium in both residential fabrication and light industrial settings. The balled tip geometry that forms during AC operation promotes arc stability and consistent weld bead control. This electrode is not recommended for DC welding, as pure tungsten does not provide the strong arc starts available with thoriated or ceriated electrode types. Welders working on aluminum sheet metal, magnesium components, and similar non-ferrous base materials will find this electrode appropriate for their GTAW setups.

Key Features

• 99.50% pure tungsten composition with green color-code identification
• Forms a stable balled tip during AC operation for consistent arc performance
• Optimized for AC balanced wave and AC sine wave welding processes
• Well-suited for aluminum and magnesium base materials
• 1/4 inch diameter, 7 inch length per electrode
• Sold as a 5-piece pack for bench stock or service van restocking

Compatibility

Designed for use in standard GTAW torches accepting 1/4 inch diameter tungsten electrodes. Appropriate for AC welding machines capable of balanced wave or sine wave output used on aluminum and magnesium workpieces.

Installation Notes

Pure tungsten electrodes are installed and replaced by qualified welders or welding technicians familiar with GTAW equipment. Power down and disconnect the welding machine before changing electrodes. Ensure the collet and collet body in the torch are sized for 1/4 inch diameter tungsten before installation. Do not use this electrode type on DC welding machines, as arc starting performance will be inferior to thoriated or ceriated alternatives.
