Tweco 1540-1104 Mig Gas Diffuser 450A Brass 5 Pack

Product Description

The TWECO 1540-1104 is a brass MIG gas diffuser designed for medium to heavy duty welding applications up to 450 amps. Machined from 360 brass alloy bar stock, it delivers consistent dimensional stability and reliable electrical conductivity under sustained load. The diffuser measures 1.25 inches in overall length and features a 3/8 inch-24UNF-2A threaded connection for secure mounting to the conductor tube. Six 0.094-inch gas ports provide uniform shielding gas distribution across the weld pool. The part number is roll-stamped on the external surface for fast field identification. Sold in a pack of 5, this diffuser is a standard consumable replacement for professional MIG welding operations.

This gas diffuser is suited for medium to heavy duty standard MIG welding environments requiring up to 450A capacity. It is compatible with 450A MIG gun series and Eliminator front-end consumable systems. Application guidance from the manufacturer specifies use with 24A series nozzles only and the 34A nozzle insulator. A built-in conduit set screw holds the conduit liner securely in position during operation, making it appropriate for production welding shops, fabrication facilities, and field welding crews handling structural or pipe work.

Installation Notes

Installation is performed by qualified welding technicians or MIG gun service personnel. Disconnect and de-energize the welding power source completely before replacing front-end consumables. Thread the diffuser onto the conductor tube by hand first to avoid cross-threading, then snug with appropriate pliers or a consumable wrench. Secure the conduit liner using the integrated set screw before reassembling nozzle components.
