Xtrweld WTE3187 E3 Purple Tungsten Electrode 3/16 X 7 in 5pk

Product Description

The XTRWELD WTE3187 is a ground E3 tungsten electrode designed for TIG welding applications. Identified by its purple color coding, the E3 designation indicates a rare-earth blend formulation that supports stable arc starts and consistent performance across a range of materials. Each electrode measures 3/16 inches in diameter and 7 inches in length, conforming to AWS A5.12 specification. This package contains 5 electrodes. Professional welders and TIG fabricators working in shop or field environments rely on ground electrodes like this for clean, repeatable arc initiation and minimal contamination of the weld pool.

This electrode is suited for TIG welding on steel, stainless steel, aluminum, and other metals where a rare-earth tungsten electrode is appropriate. The E3 formulation is a common choice for both AC and DC welding processes. Ground finish electrodes are typically preferred in precision TIG applications where surface consistency matters. This product is sold in a 5-piece pack, making it practical for ongoing shop use or job-site supply.

Key Features

• E3 rare-earth blend tungsten electrode with purple color coding per AWS A5.12
• Ground finish for consistent surface quality and reliable arc initiation
• Diameter: 3/16 inches (4.76 mm); Length: 7 inches
• Meets AWS A5.12 specification

Compatibility

Designed as a replacement or consumable tungsten electrode for TIG welding torches accepting 3/16-inch diameter electrodes. Verify collet and collet body sizing on your TIG torch before installation.

Installation Notes

Tungsten electrodes are installed by licensed welders or qualified fabricators familiar with TIG torch setup. Always disconnect the welding machine from power before changing electrodes. Grind or prepare the electrode tip to the geometry appropriate for your process and base material before striking an arc. Follow manufacturer guidelines for your TIG torch regarding proper collet torque to avoid electrode slippage or torch damage.
