The ESAB 86Z03 is a premium-grade ceramic TIG cup designed specifically for the heavy-duty HW-12 series of water-cooled TIG torches. In the demanding environment of industrial welding, the integrity of your consumables is paramount to maintaining weld quality and operational efficiency. This nozzle features a #10 orifice, translating to a 5/8-inch (approximately 16mm) bore diameter. This size is optimal for applications requiring a broader umbrella of shielding gas, essential when welding reactive metals or thicker sections where atmospheric contamination must be rigorously excluded.
Manufactured from high-purity alumina ceramic, this cup is engineered to withstand the extreme thermal cycles associated with high-amperage TIG welding. The HW-12 torch system is typically rated for up to 500 amps, generating significant radiated heat. Inferior ceramics often succumb to thermal shock, cracking mid-weld and disrupting gas flow. The ESAB 86Z03 is formulated to resist this thermal stress, providing a longer service life and reducing the frequency of consumable replacement. Its threaded base ensures a tight, concentric fit to the torch body, preventing gas leakage and ensuring that the laminar flow of argon or helium is directed precisely over the weld pool.
For procurement specialists and facility managers, standardizing on genuine ESAB parts like the 86Z03 ensures compatibility and performance consistency across your welding fleet. Whether used in aerospace, power generation, or heavy fabrication, this nozzle delivers the reliability professionals expect from the ESAB brand. It is an essential component for maintaining the precision and quality of your TIG welding operations.
