OTC Daihen Made-in-Japan Genuine Water-Cooled Torch Nozzle U2965E00 (Dual-Layer Cooling)

U2965E00 is an official Made-in-Japan genuine heavy-duty water-cooled shielding nozzle custom-engineered by OTC Daihen for extreme high-amperage, continuous welding applications. Unlike standard single-layer copper nozzles, U2965E00 utilizes an advanced dual-layer water-jacketed forged construction with integrated cooling coolant channels. It removes accumulated arc heat instantaneously, keeping the outer nozzle cool under demanding operating cycles. Re-equipping your torch with an original U2965E00 prevents severe spatter adhesion, nozzle melting, contact tip annealing, and operator burns, while its smooth interior profile delivers leak-proof laminar gas shielding.

🔧 On-Site Water-Cooled Nozzle Care & Leak Prevention Guide (Essential Reading)

Never Strike Nozzles to Remove Slag: Dual-layer water-cooled nozzles contain thin internal water jacket partitions. Never hammer workpieces with the nozzle to dislodge spatter! Mechanical impact ruptures internal cooling partitions, spraying high-pressure water into the welding arc and causing severe sponge-like weld porosity.
Prevent Coolant Scale Buildup: Always use dedicated industrial welding coolant. Operating with standard tap water causes calcium scale to clog micro-cooling channels, resulting in rapid thermal burnout and deformation within minutes of high-amperage welding.
Gentle Spatter Scraping: Clean spatter using specialized MIG reamers or round scrapers gently. Never gouge internal walls with screwdrivers or steel chisels; puncturing the inner copper jacket ruins expensive imported nozzles instantly.
Thread Alignment: Thread U2965E00 onto torch bodies smoothly by hand and apply a trace amount of conductive grease to prevent high-temperature thread seizing.
