The ESAB Nozzle 16/21 #12 (2-Pack) represents the professional standard for heavy-duty TIG welding consumables. Designed to mate perfectly with 16 Series and 21 Series TIG torches, these alumina nozzles are essential for welders operating at higher amperages or requiring extended duty cycles. The 16 and 21 series torches are known for their robust capacity, often used in automated setups or heavy manual welding, and they require consumables that match their performance capabilities. This product provides a precise fit, ensuring optimal gas flow and electrical isolation at the torch front end.
With a #12 orifice size, equivalent to 3/4-inch (19mm), this nozzle is engineered to deliver a broad, consistent column of shielding gas. This wide coverage is indispensable when welding materials sensitive to atmospheric contamination, such as titanium or stainless steel, or when using larger diameter tungsten electrodes typical of the 16/21 series. The larger cup size also allows for greater tungsten extension, improving visibility and access in difficult joints without compromising the integrity of the gas shield. The ceramic composition is formulated to resist spatter adhesion and withstand the thermal stress of high-amp arcs without fracturing.
Welders Supply Company offers these nozzles in a practical 2-pack, recognizing that consumables are a vital part of your daily workflow. Using genuine or high-quality compatible parts like these ESAB nozzles ensures that your torch operates as intended, preventing gas turbulence that can lead to porosity. Whether you are upgrading your current setup or restocking your tool crib, these #12 alumina cups provide the reliability and performance necessary for code-quality welds.
