633985 - ESAB #12 Ceramic Cup for 16/21 Series Torches

Reliable TIG Consumables for Heavy-Duty Applications

At Josef Gas, we understand that professional welders require components that can withstand the rigors of high-amperage industrial work. The ESAB Nozzle 16/21 #12 is a premium alumina ceramic cup designed specifically for the robust 16 and 21 series TIG torches. These torches are often used in heavy fabrication environments where heat management and durability are paramount. This pack of two nozzles ensures that you have a high-quality replacement ready when you need it, minimizing downtime and maintaining the consistency of your weld quality.

The #12 size offers a generous 3/4-inch (19mm) orifice, which is critical for providing a wide umbrella of shielding gas. This is particularly beneficial when welding reactive metals or when a longer tungsten stick-out is required to reach into tight corners or deep grooves. By maintaining a stable laminar flow of argon or helium, this nozzle helps prevent atmospheric contamination, resulting in cleaner, stronger welds with less oxidation. The alumina material is chosen for its excellent electrical insulation properties and resistance to thermal shock, ensuring the nozzle does not crack easily under rapid temperature changes.

Compatibility is key in maintaining a fleet of welding equipment. These nozzles are engineered to fit standard front-end configurations of the WP-16 and WP-21 style torches, which are distinct from the more common 17/18/26 series. By stocking the correct parts for your specific torch models, Josef Gas helps you avoid the frustration of mismatched components. Whether you are working on thick aluminum plate, pipe welding, or structural steel, these ESAB nozzles deliver the performance professional fabricators demand.

Key Benefits:

• Specific Fit: Tailored for 16 and 21 series heavy-duty torches.
• Enhanced Coverage: Large #12 bore ensures superior gas shielding.
• Durable Material: High-grade alumina withstands intense welding heat.
