Product Description
Grey Head Tungsten Electrode (WC20/EWCe-2) – 2% Ceriated Tungsten Needle for TIG Welding
Product Summary
Our full‑series tungsten electrodes include Red Head (WT20), Grey Head (WC20), Blue Head (WL20), Gold Head (WL15), Green Head (WP) and White Head (WZ08). Made of high‑purity tungsten mixed with rare‑earth oxides through powder metallurgy, rolling, grinding and polishing processes, they are core welding consumables for TIG welding. Featuring stable arc ignition, low ablation rate and long service life, our multi‑type electrodes meet global welding standards and satisfy different current and material welding requirements.
Overview
Our Grey Head Tungsten Electrode (WC20/EWCe-2), also known as tungsten needle/tungsten pin, is a high-performance non-radioactive TIG welding electrode formulated with 97.8% tungsten + 2.0% cerium oxide (CeO₂). Designed for precision and low-to-medium current welding, it delivers easy arc ignition, stable arc performance, and minimal burn-off—ideal for thin sheets, delicate components, and general-purpose DC welding. The grey tip complies with ISO 6848 color coding for instant identification.
Key Features (Properties)
- Non-Radioactive & Eco-Friendly: Contains no thorium; safe for operators and compliant with global environmental standards.
- Easy Arc Starting & Re-Ignition: Low electron emission work function ensures quick, consistent arc starts even at low DC currents.
- Superior Arc Stability: Stable arc with no wandering or spitting; precise heat control for clean weld beads.
- High Chemical Stability: Resists oxidation and contamination; maintains tip shape longer for consistent performance.
- Low Erosion & Long Service Life: Reduced burn-off rate extends lifespan compared to pure tungsten (WP/green).
- Versatile Current Range: Optimized for 5–250A DC; works with most inverter TIG welders.
Applications (Uses)
Perfect for DCEN (DC Electrode Negative) welding on:
- Carbon steel / Mild steel
- Stainless steel (304/316, etc.)
- Copper & copper alloys (bronze, silicon bronze)
- Titanium & nickel alloys
- Thin sheets (0.5–4mm) & precision parts
- Pipe fabrication, automotive, aerospace, and general metalworking
Specifications (Standard Sizes)
- Custom lengths available upon request.
- Packaging: Vacuum-sealed (10pcs/tube, 5/10 tubes/box) to prevent oxidation during storage.
Advantages
- Safety First: Non-radioactive cerium oxide replacement for thorium; eliminates health risks and regulatory concerns.
- Cost-Effective: Longer life and less downtime vs. pure tungsten; lower total cost than thoriated (red) electrodes.
- Precision Welding: Ideal for thin materials and tight tolerances; minimal heat input reduces distortion.
- User-Friendly: Easy to use for beginners; reliable re-ignition for tack welds and intermittent work.
- Global Compliance: Meets ISO 6848, AWS A5.12, and CE standards; suitable for export worldwide.
Why Choose Our Grey Head Tungsten Electrodes?
- Premium Raw Material: High-purity tungsten powder + rare earth additives for consistent quality.
- Precision Manufacturing: Strict quality control for diameter straightness, tip concentricity, and surface finish.
- Stable Supply: Large inventory of standard sizes; fast delivery and OEM support.
- Trusted by Welders: Widely used in metal fabrication, repair, and industrial production across Europe, Southeast Asia, and the Middle East.
FAQ
Q: Can I use grey head electrodes for AC welding?
A: Yes, but they perform best on DCEN. For AC aluminum/magnesium, choose pure tungsten (green) or zirconiated (brown) electrodes.
Q: What current should I use for a 2.4mm grey head electrode?
A: Recommended range: 80–150A DC for 1–3mm steel/stainless steel.
Q: How to store tungsten electrodes?
A: Keep in dry, sealed packaging to avoid moisture and oxidation; do not touch tips with bare hands.
