OVERVIEW

Precision TIG Welding with Weldcraft 2% Ceriated Tungsten

The Weldcraft WC040X7 2% Ceriated Tungsten Electrode is a premium-grade consumable designed for the most demanding Gas Tungsten Arc Welding (GTAW) applications. Identified by its gray color code and AWS classification EWCe-2, this electrode contains a minimum of 97.3% tungsten and 1.8% to 2.2% cerium oxide. This specific formulation allows the electrode to perform exceptionally well in low-amperage settings, making it the superior choice for orbital tube welding, pipe fabricating, and thin sheet metal work where heat input control is critical.

Unlike thoriated tungsten, ceriated electrodes are non-radioactive, eliminating the safety concerns associated with handling and grinding radioactive materials. Despite being a safer alternative, they offer comparable, if not superior, performance in specific ranges. The cerium oxide additive migrates to the tip of the electrode during welding, which lowers the work function of the material. This results in easier arc starting, improved arc stability, and reduced erosion rates. For fabricators working with the 0.040-inch (1.0 mm) diameter, this stability is essential for maintaining a focused arc on delicate substrates without burning through the base material.

This tungsten is highly versatile, capable of operating proficiently in both DCEN (Direct Current Electrode Negative) and AC (Alternating Current) processes. While it is widely recognized as the standard for DC welding of carbon steel, stainless steel, nickel alloys, and titanium, it is also increasingly used with inverter-based power sources for AC welding of aluminum and magnesium. The 0.040-inch diameter is specifically tailored for very low amperage applications, providing the fine control necessary for micro-TIG applications and intricate repairs.

Weldcraft, a brand synonymous with quality in the TIG welding industry, ensures that each electrode undergoes rigorous testing to meet industry standards for straightness, density, and chemical composition. This 10-pack of 7-inch electrodes ensures you have a consistent supply of high-quality consumables to maintain productivity and weld quality in your shop or field operations.

FAQ

The main advantage is its excellent arc starting and stability at low amperages, combined with the fact that it is non-radioactive, making it a safer alternative to thoriated tungsten.

Yes, 2% Ceriated tungsten works well for AC welding of aluminum, especially when used with modern inverter-based TIG welding machines.

The color code for 2% Ceriated tungsten (EWCe-2) is Gray (formerly orange in some standards, but Gray is the current standard for this Weldcraft product).

No, 2% Ceriated tungsten is non-radioactive, unlike 2% Thoriated (Red) tungsten, making it safer to grind and handle.

You can weld Carbon Steel, Stainless Steel, Nickel Alloys, Titanium, Aluminum, and Magnesium.

The 0.040-inch diameter is designed for very low amperage welding on thin materials. It allows for a focused arc that won't blow through delicate parts.

For DC welding, grind the tungsten longitudinally to a point. For AC welding on inverters, a pointed or slightly truncated tip is often used; on transformers, it may ball slightly.

Yes, the electrodes are supplied in a protective plastic case that holds the 10 electrodes securely.
