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.\u003c\/p\u003e\u003cp\u003eThis 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.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eE3 rare-earth blend tungsten electrode with purple color coding per AWS A5.12\u003c\/li\u003e\n\u003cli\u003eGround finish for consistent surface quality and reliable arc initiation\u003c\/li\u003e\n\u003cli\u003eDiameter: 3\/16 inches (4.76 mm); Length: 7 inches\u003c\/li\u003e\n\u003cli\u003eMeets AWS A5.12 specification\u003c\/li\u003e\n\u003cli\u003eSold as a 5-piece pack\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a replacement or consumable tungsten electrode for TIG welding torches accepting 3\/16-inch diameter electrodes.

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.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eElectrode Type\u003c\/strong\u003e: E3 Rare-Earth Blend\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor Code\u003c\/strong\u003e: Purple\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Ground\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: AWS A5.12\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity per Pack\u003c\/strong\u003e: 5 pieces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 1.543 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: XTRWELD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: WTE3187\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"XTRWELD","offers":[{"title":"Default Title","offer_id":51343511617842,"sku":"WTE3187","price":95.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310546994.jpg?v=1782022247","url":"https:\/\/voomisupply.com\/products\/xtrweld-wte3187-e3-purple-tungsten-electrode-3-16-x-7-in-5pk","provider":"Voomi Supply","version":"1.0","type":"link"}
