Tweco 1550-1102 Gas Diffuser 500 Amp Mig Welding

Product Description

The TWECO 1550-1102 is a standard duty tellurium copper gas diffuser rated for MIG welding applications up to 500 amps. Machined from tellurium copper alloy bar stock, it delivers consistent dimensional stability and reliable electrical conductivity across medium to heavy duty welding cycles. The part number is rolled and stamped on the external surface for quick field identification. A conduit set screw secures a 3/32-inch conduit liner in place, and the unit features a properly threaded conductor tube for direct connection to compatible MIG guns. Sold in a pack of 5.

This gas diffuser is designed for medium to heavy duty MIG welding applications where sustained high-amperage output is required. It is compatible with the No. 5 MIG gun series and Eliminator front-end consumables. The diffuser works with 45H-332, 45H-764, and 45H-18 conduits, making it a fit for a range of standard MIG gun configurations in fabrication shops, structural welding, and industrial maintenance environments.
