Tweco 1240-1216 Mig Welding Nozzle 5/8 in Bore

Product Description

The TWECO 1240-1216 is a heavy-duty nozzle designed for robotic MIG welding guns. It features a 5/8 inch bore diameter and a 1/8 inch recessed tip, a geometry that protects the contact tip from spatter and helps maintain a consistent arc distance during automated welding cycles. The recessed configuration also reduces nozzle-to-work interference in tight joint access situations. Welding technicians and robotic cell integrators install this nozzle as a direct service replacement to maintain weld quality and extend gun service life.

This nozzle is intended for use with Tweco robotic MIG guns in production welding environments. The heavy-duty construction suits high-duty-cycle robotic applications where consistent gas coverage and nozzle longevity are critical. It is sold individually and is appropriate for facilities running automated MIG welding cells that require periodic nozzle replacement as part of scheduled preventive maintenance.

Key Features

• 5/8 inch bore diameter for consistent shielding gas coverage
• 1/8 inch recessed tip geometry reduces spatter accumulation on the contact tip
• Heavy-duty construction rated for high-duty-cycle robotic welding applications
• Compatible with Tweco robotic MIG gun platforms
• Compact form factor at 3.2 inches in length

Compatibility

Designed for use with Tweco robotic MIG guns. Refer to your gun manufacturer documentation to confirm nozzle thread and bore fitment before installation.

Installation Notes

Installation is performed by welding technicians or robotic cell maintenance personnel. Always de-energize the welding power source and allow the gun neck to cool before removing or installing a nozzle. Thread the nozzle on by hand first to avoid cross-threading, then seat it fully. Inspect the gas diffuser and contact tip for wear at each nozzle change interval.
