Tweco 1240-1342 Robotic Mig Welding Nozzle Water-cooled

Product Description

The TWECO 1240-1342 is a water-cooled robotic MIG welding nozzle designed for the RCW24 robotic and fixed-automation MIG gun platform. Machined from tellurium copper alloy bar stock, the nozzle housing delivers consistent dimensional stability and efficient heat dissipation during continuous welding cycles. The nozzle supports medium to heavy-duty welding applications rated up to 400 amps and features a 5/8-inch diameter straight bore that enables thorough cleaning of sidewall surfaces to maintain reliable shielding gas flow. Each unit ships with a G7 silicone spatter shield for added protection.

This nozzle is built for robotic and fixed-automation MIG welding environments where consistent, repeatable torch geometry is critical. The bottle-shaped geometry and straight inner-diameter bore make it well suited for use with nozzle cleaning stations integrated into robotic weld cells. Typical installations include medium to heavy-duty automated MIG welding operations running up to 400 A, where water-cooled consumables are required to sustain duty cycles that air-cooled nozzles cannot support. The part number is roll-stamped on the exterior surface for quick identification during maintenance.

Key Features

Compatibility

Designed for use with the Tweco RCW24 robotic and fixed-automation water-cooled MIG gun platform. Compatible with robotic weld cells that incorporate an automated nozzle cleaning station.

Installation Notes

Installation and replacement should be performed by a qualified welding technician or automation maintenance professional. Shut down the welding power source and depressurize the water-cooling circuit before removing or installing the nozzle. The nozzle threads onto the outer jacket assembly of the water-cooled conductor tube — ensure threads are clean and free of spatter buildup before seating. Follow all applicable AWS and equipment manufacturer safety guidelines when servicing robotic weld cell consumables.
