12301084 - Tweco Spray Master Spatter Shield / Diffuser Insulator

Keep Your Spray Master Running Clean

If you are running a Tweco Spray Master gun—whether it's the 250, 350, or the big 450—you know that spatter is the enemy. It gets everywhere, clogs your nozzle, and ruins your gas flow. That's where the Tweco 1230-1084 Spatter Shield comes in. This little part does a huge job. It sits right inside your front-end assembly, acting as a bodyguard for your gas diffuser. It stops spatter from caking up where it shouldn't and keeps your nozzle electrically insulated from the hot parts.

We've all been there: you're in the middle of a long bead, and suddenly your arc starts sputtering or your nozzle shorts out against the workpiece. Often, that's because the insulator or spatter shield is fried, cracked, or missing. The 1230-1084 is built tough to handle the heat. It's made from a durable composite that doesn't just melt away after a few hours of arc time. It’s designed to take a beating so your expensive brass parts don't have to.

Swapping these out is a breeze. When you are changing your contact tip or cleaning out your nozzle, take a second to check the shield. If it looks charred or cracked, toss it and pop in a fresh 1230-1084. It’s cheap insurance against bad welds and frustrated operators. Using genuine Tweco parts means you don't have to fight to get it to fit; it slides right into place and stays there.

Don't let a worn-out insulator ruin your day or your weld quality. Keep a few of these spatter shields in your toolbox. They are the unsung heroes of the MIG gun world, keeping the gas flowing smooth and the sparks flying only where they are supposed to. Grab a pack and keep your Spray Master performing like the day you bought it.
