Tweco 1640-1398 Velocity Nozzle Mig Torch

Product Description

The TWECO 1640-1398 is a Velocity series nozzle designed for MIG welding torch applications. The nozzle directs shielding gas flow around the weld pool, protecting the molten metal from atmospheric contamination during the welding process. It is a consumable front-end component installed on compatible TWECO MIG torch bodies. Welding technicians and fabricators replace nozzles routinely as part of standard torch maintenance to maintain consistent shielding gas coverage and weld quality. The compact form factor and lightweight construction make it a straightforward field replacement.

This nozzle is suited for MIG welding operations in fabrication shops, manufacturing environments, and field welding applications where TWECO Velocity series torch consumables are specified. It is sold individually, making it practical for single-unit replacement during scheduled or unscheduled torch servicing. Professionals working with TWECO torch systems will recognize it as a standard maintenance item.

Key Features

• Velocity series nozzle design for consistent shielding gas flow
• Compact profile with approximately 0.92 inch length, width, and height
• Lightweight at 0.01 pounds for easy handling during torch changeover

Compatibility

Designed as an OEM-style replacement nozzle for TWECO Velocity series MIG torch assemblies. Verify torch model and front-end configuration before ordering to confirm fitment.

Installation Notes

Nozzle replacement should be performed by a qualified welding technician following standard lockout/tagout procedures with the welder powered down before servicing the torch. Thread or press the nozzle onto the torch body according to the torch manufacturer's instructions, taking care not to cross-thread or overtighten. Inspect the contact tip and gas diffuser for wear during each nozzle replacement to maximize torch performance and consumable service life.
