OTC Daihen Genuine Manual Welding Torch Nozzle KA3116 (16mm Bore / For WT3510SBD)
KA3116 is an official OEM genuine gas shielding nozzle custom-engineered by OTC Daihen for heavy-duty manual gas-shielded welding torches (WT3510SBD series). Operating as the primary shield against intense arc radiation and molten spatter, this nozzle is cold-forged and precision-machined from thick-walled, high-conductivity copper alloy. Its standardized 16mm inner diameter and smooth internal hydrodynamic contour constrict CO2 or mixed shielding gas into a dense, laminar protective curtain around the molten weld pool. Re-equipping your torch with an original KA3116 eliminates spatter adhesion, nozzle melting, gas turbulence, and weld porosity associated with thin-walled aftermarket substitutes.

🔧 On-Site Consumable Assembly & Torch Care Guide (Essential Reading)
- Never Use Nozzles as Slag Hammers: Never strike steel plates with the KA3116 nozzle to knock away slag! Copper alloy is malleable; mechanical impact deforms the 16mm circular orifice into an oval profile. Deformed openings cause gas turbulence, arc deflection, and severe weld porosity.
- Prevent Spatter Bridging & Short Circuits: Heavy-amperage welding generates spatter buildup inside the nozzle. If spatter bridges the gap between the nozzle and energized contact tip, accidental contact with grounded workpieces causes destructive short circuits. Clean inner walls regularly with nozzle pliers and apply anti-spatter compound.
- Proper Anti-Spatter Gel Application: Dip only the front 1-2 cm of warm nozzles into anti-spatter paste. Never submerge entire torch heads, as melted paste flows into gas diffusers and blocks shielding gas orifices.
- Inspect Insulating Sleeves: Nozzles seat onto torch necks via insulating sleeves. Never force nozzles onto cracked or carbonized insulators, as loose seating allows the nozzle to touch contact tips and burn through copper walls.
