OVERVIEW

Precision-Engineered 35-50 Gas Diffuser for MIG Welding

The 35-50 Gas Diffuser is a critical component designed to maintain the efficiency and performance of your MIG welding setup. Manufactured to precise specifications, this diffuser is fully compatible with Tweco #1 series and Lincoln Magnum 100L MIG guns, making it a versatile choice for fabrication shops and hobbyists alike. Constructed from high-grade 360 brass alloy bar stock, the diffuser offers superior dimensional stability and resistance to thermal deformation, ensuring it maintains its shape even during prolonged welding sessions.

Engineered for light-duty applications, this component is rated for use up to 200 amperes, providing ample capacity for standard MIG welding tasks. The outer surface features finely machined threads that allow for the secure attachment of nozzle assemblies, ensuring they remain firmly in place during operation. This tight fit is essential for maintaining proper gas coverage over the weld pool, preventing porosity and ensuring a clean, high-quality weld. The internal geometry is optimized to facilitate smooth gas flow around the contact tip, aiding in cooling and extending the lifespan of your consumables.

As a direct replacement for the Tweco 1500-1100 part, this generic 35-50 diffuser delivers OEM-level performance at a competitive value. Whether you are repairing a damaged gun or stocking up on routine maintenance parts, this brass diffuser provides the reliability and consistency required for professional results. Its robust construction ensures it can withstand the rigors of daily use while maintaining excellent electrical conductivity for a stable arc.

FAQ

This 35-50 gas diffuser is compatible with Tweco #1 series guns and Lincoln Magnum 100L guns, as well as many other generic 100-series MIG guns.

It is machined from 360 brass alloy, which provides excellent durability, heat resistance, and electrical conductivity.

This diffuser is designed for light-duty welding applications and is rated for up to 200 amperes.

Yes, it features machined threads on the outside surface specifically designed to allow nozzle assemblies to thread over and hold firmly in place.

No, this is a high-quality generic 'Tweco Style' replacement part that meets or exceeds the specifications of the original Tweco 35-50 (1500-1100).

You should replace the diffuser if the threads are stripped, the gas holes are clogged with spatter that cannot be removed, or if it shows signs of excessive heat damage or deformation.

This diffuser typically accepts standard Tweco 11-series contact tips (e.g., 11-30, 11-35) which screw into the diffuser.
