AK4C - Weldcraft AK4C TIG Torch Consumable Kit with Ceriated Tungsten

Genuine Weldcraft AK4C Accessory Kit for 20 Series Torches

Maximize the performance of your water-cooled TIG welding setup with the Weldcraft AK4C TIG Torch Accessory Kit. This curated package is designed to support the 20 Series family of torches, including the Weldcraft W-250, W-280, and W-375 models. For professional welders who demand reliability and precision, using genuine Weldcraft parts is critical to maintaining the integrity of the welding arc and the longevity of the torch head. This kit bundles the most frequently used consumables into one convenient package, ensuring you have the right parts on hand when you need them.

Optimized for DC Welding Applications
The AK4C kit features 2% Ceriated tungsten electrodes, identified by their grey color code. Ceriated tungsten is an excellent all-purpose electrode that offers distinct advantages over pure tungsten. It provides reliable arc starting at low voltages and maintains a stable arc throughout the welding process. While it can be used for AC welding on aluminum with modern inverters, it truly excels in DC welding of mild steel and stainless steel. The electrodes included come in 7-inch lengths and cover the three most common diameters: 1/16-inch, 3/32-inch, and 1/8-inch.

Comprehensive Consumable Selection
To complement the electrodes, the kit supplies a full set of front-end parts. You receive three collets and three collet bodies corresponding to the electrode sizes, ensuring a tight tolerance fit that promotes efficient current transfer and heat dissipation. The kit also includes three Alumina nozzles in sizes #5, #6, and #7. These ceramic cups are designed to withstand high heat and direct shielding gas effectively over the weld pool, reducing the risk of porosity and contamination. A long back cap is included to accommodate full-length tungsten electrodes, providing balance and handling comfort.

Compatibility and Convenience
Designed for the 250-amp to 375-amp range of water-cooled torches, this kit is the standard for the industry-favorite WP-20 style torch. Having a dedicated accessory kit like the AK4C simplifies inventory management and ensures that all components are compatible with one another. Whether you are working in aerospace, motorsports fabrication, or industrial pipe welding, the Weldcraft AK4C kit delivers the quality and consistency required for high-stakes welding operations.
