Tweco 1260-1687 EL22I Insulated Nozzle 5/8 Inch Bore

Product Description

The TWECO 1260-1687 is an EL22I insulated MIG welding nozzle with a 5/8 inch bore, designed for use on compatible TWECO-style MIG guns and torch bodies. The insulated construction helps reduce the risk of arc-out caused by contact between the nozzle and the workpiece or weld puddle, making it a practical choice for applications where tip-to-work clearance is limited. At 0.16 pounds and compact in size, this nozzle is a direct consumable replacement for welding operations that demand consistent gas coverage and reliable arc performance. Welding technicians and fabricators install this component as part of routine gun maintenance.

This nozzle is suited for MIG welding applications in light industrial, fabrication, and maintenance environments. The 5/8 inch bore accommodates standard contact tip sizes used in short-circuit and spray transfer welding processes. Its insulated design is particularly useful in tight joint configurations or when working close to conductive surfaces. The EL22I designation identifies this as part of the TWECO EL-series insulated nozzle family, which is a common consumable format across a range of semi-automatic MIG gun assemblies.

Key Features

• 5/8 inch bore diameter for compatibility with standard MIG contact tip sizing
• Insulated nozzle construction reduces arc-out risk during close-clearance welding
• Lightweight at 0.16 pounds for minimal added mass on the gun assembly
• EL22I series designation for straightforward consumable identification and reordering
• Sold individually as a direct drop-in consumable replacement

Compatibility

Designed as an OEM-style replacement consumable nozzle for TWECO-compatible semi-automatic MIG gun assemblies using the EL22I insulated nozzle format with a 5/8 inch bore.

Installation Notes

Nozzle replacement is performed by welding technicians as part of routine MIG gun maintenance. Disconnect the welding machine from power and allow the gun to cool completely before removing the worn nozzle. Thread or press the replacement nozzle onto the gun body per the gun manufacturer's assembly procedure, ensuring a secure fit to maintain proper shielding gas flow. Inspect the contact tip and liner condition whenever replacing the nozzle.
