If you are running a Tweco No. 3 or No. 4 MIG gun, you know that the front-end consumables take a beating. The gas diffuser is the heart of that assembly, and when it gets clogged with spatter or the threads get stripped, your arc stability suffers. This 5-pack of Tweco 54A Gas Diffusers (1540-1110) is the perfect way to keep your torch in top shape without constantly reordering single parts.
These are genuine brass diffusers designed for the classic slip-on nozzle setup. They screw right onto your conductor tube and hold your 14 Series contact tips securely. Because they are made from high-quality brass, they handle the heat of 300A to 400A welding applications without deforming or losing conductivity. The gas holes are designed to give you a smooth, even shield of gas, which helps keep your puddles clean and porosity-free.
Don't let a worn-out diffuser ruin your contact tips or cause erratic feeding. Swapping out an old, spatter-covered diffuser is one of the cheapest and easiest ways to troubleshoot a bad arc. With this 5-pack, you can keep a few spares in your toolbox or on your welding cart, so you're never stuck waiting for parts in the middle of a job. Compatible with standard slip-on nozzles (24A series) and 34A insulators.
