Tweco 1240-1332 Robotic Mig Nozzle 400A Water-cooled

Product Description

The TWECO 1240-1332 is a water-cooled robotic MIG welding nozzle rated for medium to heavy-duty applications up to 400 amps. Designed for robotic and fixed automation MIG guns, it features bottle-shaped geometry and a straight inner-diameter bore that allows nozzle cleaning stations to effectively clear the sidewalls for consistent shielding gas flow. The nozzle housing is machined from tellurium copper alloy bar, a material chosen for its superior thermal conductivity and dimensional stability under sustained high-amperage welding cycles. A G7 silicone spatter shield is included with each nozzle. The bore diameter is 5/8 inches. Licensed welding technicians and automation integrators install this component in robotic weld cells.

This nozzle is engineered for integration into robotic weld cells where a nozzle cleaning station is incorporated into the automated workflow. The straight inner-diameter bore geometry is specifically suited to reamer-style cleaning stations, ensuring consistent gas coverage pass after pass. The bottle-shaped profile accommodates the conductor tube geometry common to water-cooled robotic MIG torch assemblies. The nozzle threads directly onto the outer jacket assembly of water-cooled conductor tubes, making it a direct fit for compatible robotic torch configurations used in medium to heavy industrial fabrication environments.

Compatibility

Designed for use with robotic and fixed automation MIG guns equipped with water-cooled conductor tubes; the nozzle threads onto the outer jacket assembly of compatible water-cooled conductor tube systems. Intended for use with nozzle cleaning stations integrated in robotic weld cells.

Installation Notes

Installation and replacement should be performed by a qualified welding technician or automation maintenance technician. Shut down and de-energize the welding power source and allow the water-cooled torch assembly to depressurize and cool before handling. Thread the nozzle securely onto the outer jacket of the conductor tube by hand before final tightening to avoid cross-threading. Verify shielding gas flow and check for spatter buildup around the bore after the first weld cycle to confirm proper seating and gas coverage.
