CK Worldwide T0409S20GC2 Tungsten Electrode 0.040" 2% Ceriated

Professional-grade 2% ceriated tungsten electrode in .040" diameter delivers superior arc starting performance and extended electrode life for precision TIG welding applications. Ceriated tungsten provides excellent arc initiation at lower amperages while maintaining stable arc characteristics across a wide current range.

This tungsten electrode excels in both AC and DC welding applications, offering consistent performance on aluminum, stainless steel, and mild steel. The 2% cerium oxide content enhances electron emission properties, resulting in easier arc starts and reduced tungsten consumption compared to pure tungsten electrodes.

• Diameter: .040" (1.0mm)
• Composition: 2% Ceriated Tungsten
• Current Type: AC/DC compatible
• Arc Starting: Superior low-amperage initiation
• Manufacturer SKU: T0409S20GC2
• Application: Precision TIG welding

The .040" diameter makes this electrode ideal for fine detail work, thin material welding, and applications requiring precise heat control. Ceriated tungsten electrodes maintain their tip geometry longer than thoriated alternatives while providing comparable welding performance without radioactive content concerns.

Compatible with standard TIG torches and collet systems designed for .040" tungsten electrodes. Recommended for professional welders working on precision fabrication, aerospace components, and thin-gauge materials where consistent arc quality and electrode longevity are critical.
