A TIG ceramic cup is a critical consumable providing reliable gas shielding for the weld pool and electrode in GTAW applications. Our cups are manufactured from high-purity alumina (aluminum oxide), offering exceptional heat resistance and thermal shock stability under intense arc temperatures. Precision-molded to meet global standardized specifications, they ensure balanced gas flow for consistent, contamination-free welding results across all professional industrial environments.
These alumina nozzles support a broad amperage range and are fully compatible with industry-standard air-cooled and water-cooled torch series, including the 9, 17, 18, 20, and 26 platforms. They are engineered to integrate seamlessly with corresponding front-end components, such as the 13N and 10N series collet bodies, providing a secure fit and optimal shielding for diverse torch configurations and global equipment brands.
Our production range covers all standard orifice diameters, typically from size #4 (1/4″) to #12 (3/4″), allowing selection based on specific gas coverage and arc visibility requirements. From precision automotive repair to heavy-duty industrial fabrication and maintenance, these durable ceramic nozzles provide the longevity and performance consistency essential for high-quality, professional welding operations.

Frequently Asked Questions
What is a TIG Ceramic Cup and what is its primary function?
A TIG Ceramic Cup, also known as an alumina nozzle, is a critical consumable that threads onto the TIG torch. Its primary functions are to focus the shielding gas flow over the weld pool and protect the tungsten electrode from atmospheric contamination, ensuring clean and high-quality welds.
What material are these cups made from and what performance advantages does this provide?
RAX Industrial TIG Ceramic Cups are manufactured from high-purity alumina ceramic (aluminum oxide). This professional-grade construction delivers several advantages:
- Extreme Heat Resistance: Withstands intense welding temperatures without deformation or melting.
- Thermal Shock Stability: High resistance to cracking during rapid temperature changes.
- Industrial Durability: Engineered for long-term use in demanding fabrication environments.
- Optimized Gas Flow: Precision-molded to provide balanced, laminar shielding gas coverage.
How do gas lens ceramic cups differ from standard cups?
Gas lens ceramic cups are designed with a wider base to accommodate gas lens collet bodies. Unlike standard alumina nozzles, they work with the gas lens mesh to transform turbulent gas into a smooth, laminar flow. This provides superior shielding coverage and allows the welder to extend the tungsten further for better visibility and access to tight joints.
What welding applications are these cups best suited for?
Our ceramic cups are suitable for a wide range of TIG welding applications, including aerospace, automotive, metal fabrication, and industrial maintenance. They are essential for any project requiring precise gas coverage, such as fillet welds, root passes on pipe, and welding reactive metals like stainless steel or aluminum.
What sizes are available and how do I choose the right one?
We provide a full range of standard sizes, including #4 (1/4″), #5 (5/16″), #6 (3/8″), #7 (7/16″), #8 (1/2″), #10 (5/8″), and #12 (3/4″). These numbers represent the orifice diameter in sixteenths of an inch.
The choice depends on the weld joint and amperage: smaller cups (like #4 or #5) offer better access in confined spaces, while larger cups (like #8 or #12) provide the broader gas coverage needed for high-amperage industrial welding. Our production covers both the 13N series (for small torches) and the 10N series (for large torches).
Are these TIG Ceramic Cups compatible with my existing torch?
Yes, our cups are manufactured to universal industry specifications, ensuring compatibility with all major TIG torch brands. They are designed for industry-standard series including 9, 17, 18, 20, 24, 25, and 26. These cups utilize standard threading (such as 13/32″-16 UNS for the 10N series) to ensure a secure fit with both air-cooled and water-cooled configurations. Always match the cup series (10N or 13N) to your specific collet body type.
