The Tweco 1550-1120 (Model 55) Gas Diffuser is a critical replacement part for professional welders utilizing the legendary Tweco No. 5 MIG gun platform. As the bridge between the gooseneck and the contact tip, the gas diffuser performs two essential functions: it conducts the welding current and disperses the shielding gas. This specific model is engineered to meet the demanding requirements of heavy industrial welding, offering a robust solution for 500-amp applications.
Constructed from high-grade brass, the Model 55 diffuser offers excellent thermal and electrical conductivity. This material choice helps dissipate heat effectively, prolonging the life of both the diffuser and the attached contact tip. The unit features a threaded connection for the conductor tube and a standard thread for 15 Series contact tips, ensuring a tight, electrically sound connection that resists loosening due to thermal expansion and vibration. Additionally, the external geometry is machined to accommodate 24 Series slip-on nozzles, providing a friction fit that is secure yet easy to remove for spatter removal.
Supplied in a convenient pack of 5, these diffusers are an economical choice for maintenance departments and welding shops. Regular inspection and replacement of the gas diffuser are recommended to prevent gas flow restrictions caused by spatter buildup, which can lead to weld defects. By choosing genuine Tweco parts, you ensure that your MIG gun maintains the correct stick-out and gas coverage parameters intended by the manufacturer.
