Tweco 1550-1120 Gas Diffuser Mig Welding 5 Pack

Product Description

The TWECO 1550-1120 is a standard gas diffuser designed for use with MIG welding guns in medium to heavy duty welding applications. Machined from tellurium copper alloy bar stock, this diffuser delivers consistent dimensional stability and reliable electrical conductivity throughout its service life. The part number is rolled and stamped directly on the external surface for fast field identification. A properly threaded conductor tube interface ensures secure, repeatable installation on compatible MIG gun assemblies. Sold in a pack of 5, the 1550-1120 suits shops and field crews that rotate consumables at high frequency.

This gas diffuser is intended for medium to heavy duty MIG welding setups where consistent gas coverage and electrical performance are critical. It threads directly into the conductor tube of MIG guns and supports stable arc starts and steady shielding gas flow to the nozzle. Welding professionals working in fabrication, structural, and general industrial environments will find this diffuser a direct-fit consumable replacement during routine gun maintenance.

Key Features

• Tellurium copper alloy bar stock construction for consistent dimensional stability and electrical conductivity
• Part number rolled and stamped on external surface for quick identification during consumable changes
• Threaded conductor tube interface for secure, repeatable installation on compatible MIG guns
• Rated for medium to heavy duty standard welding applications
• Sold as a pack of 5 units for efficient consumable stocking

Compatibility

Designed as an OEM-style replacement gas diffuser for compatible TWECO MIG gun assemblies requiring a standard threaded diffuser consumable.

Installation Notes

Gas diffuser replacement is performed by licensed welding technicians or qualified welding equipment maintenance personnel. Before servicing the MIG gun, disconnect the welding power source and allow the gun to cool completely. Thread the diffuser into the conductor tube by hand until snug, then tighten to secure fit without over-torquing the threads. Inspect the contact tip and nozzle for wear at the same time to maintain consistent weld quality.
