Product Overview
Upgrade your TIG welding performance with our premium 4.0mm Thoriated Tungsten Electrodes (Red Tip) — the industry-standard choice for welders working with stainless steel and mild steel. Known for their excellent arc stability, superior current-carrying capacity, and long-lasting performance, these red-tipped tungstens are a trusted staple in workshops, fabrication shops, and industrial welding applications across Australia and beyond.
Whether you're a professional welder, fabricator, or DIY enthusiast, this thoriated tungsten delivers the precision and reliability you need for clean, high-quality TIG welds every time.
Key Features
- Diameter: 4.0mm — suited for medium-to-heavy-duty welding applications
- Composition: 2% Thoriated Tungsten (Red Tip / EWTh-2)
- Color Code: Red — for quick, easy identification
- Best For: Stainless steel and mild steel welding (DC applications)
- Excellent Arc Starting: Fast, stable arc ignition even at lower amperages
- High Current Tolerance: Handles higher amperage loads without excessive tip wear
- Sharp Point Retention: Maintains a fine, pointed tip for precise, focused arcs
- Low Contamination Risk: Minimal spitting or splitting during use
- Durability: Long electrode life reduces the need for frequent replacement
Why Choose Thoriated Tungsten Electrodes?
Thoriated tungstens (red tip) have long been favored by professional welders for their outstanding performance on DC (Direct Current) welding, particularly with stainless steel, mild steel, carbon steel, and other ferrous metals. Their ability to sustain a sharpened point under high heat makes them ideal for jobs requiring precision, deep penetration, and a stable, focused arc.
Compared to pure tungsten, thoriated electrodes offer:
- Better electron emission for easier arc starts
- Higher current-carrying capacity
- Reduced tungsten spitting and contamination
- Longer usable life between re-grinding
Recommended Applications
- Structural steel fabrication
- Stainless steel pipe and tube welding
- Automotive and workshop repairs
- Manufacturing and metal fabrication
- General mild steel welding projects

Note: Always follow appropriate safety and handling guidelines when working with thoriated tungsten, including proper grinding ventilation and PPE, as per local workplace safety regulations. During manufacturing, thorium is evenly dispersed throughout the electrode. This evenness allows the electrode to maintain a sharpened edge—the ideal electrode shape for welding thin steel. Sharpening the electrode’s point, however, should be done with great care. Thorium is radioactive; therefore, you must always follow manufacture’s warnings, instructions and the MSDS (Material Safety Data Sheet) for its use.
