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.\u003c\/p\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e99.50% pure tungsten composition with green color-code identification\u003c\/li\u003e\n\u003cli\u003eForms a stable balled tip during AC operation for consistent arc performance\u003c\/li\u003e\n\u003cli\u003eOptimized for AC balanced wave and AC sine wave welding processes\u003c\/li\u003e\n\u003cli\u003eWell-suited for aluminum and magnesium base materials\u003c\/li\u003e\n\u003cli\u003e1\/4 inch diameter, 7 inch length per electrode\u003c\/li\u003e\n\u003cli\u003eSold as a 5-piece pack for bench stock or service van restocking\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard GTAW torches accepting 1\/4 inch diameter tungsten electrodes.

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.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTungsten Content\u003c\/strong\u003e: 99.50% pure tungsten\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor Code\u003c\/strong\u003e: Green\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePieces per Pack\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.75 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWelding Process\u003c\/strong\u003e: GTAW (Gas Tungsten Arc Welding)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended Current Type\u003c\/strong\u003e: AC (balanced wave and sine wave)\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: WTPURE250\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"XTRWELD","offers":[{"title":"Default Title","offer_id":51343317074226,"sku":"WTPURE250","price":1520.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310547025.jpg?v=1782020010","url":"https:\/\/voomisupply.com\/products\/xtrweld-wtpure250-pure-tungsten-electrode-1-4-inch-5-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
