Keep your MIG gun running smoothly with the Tweco 14T-30 Contact Tip. Known by the part number 1140-1301, this is the go-to replacement tip for welders running 0.030" (0.8mm) wire through Tweco Classic and Spray Master MIG guns. When your arc starts to wander or the wire begins to drag, it is often a sign that the contact tip bore has worn out (keyholed). Swapping in a fresh, genuine Tweco tip restores the electrical contact necessary for a crisp, sizzling arc and superior bead profile.
While generic copies exist, genuine Tweco consumables are built to a higher standard of precision. The 14T-30 is machined from premium copper to handle the heat and current of day-to-day welding. The interior bore is smooth and perfectly sized to guide 0.030" wire with minimal friction, preventing the "stick-slip" feeding issues that can ruin a perfect weld pass. The exterior is machined with a flat surface for easy tightening with standard MIG pliers or a wrench, ensuring a secure seat against the gas diffuser to prevent gas leaks or loose connections.
The 14 Series contact tip is one of the most versatile consumables in the welding world. It fits the legendary Tweco No. 2, No. 3, and No. 4 air-cooled guns, as well as the modern Spray Master 250, 350, and 450 series. It is also compatible with many "Tweco-style" aftermarket guns that utilize the 14-series geometry. If your gun uses a 52-series gas diffuser, this is the tip you need.
Sold in a convenient pack of 25, this SKU ensures you aren't constantly reordering or running to the supply store in the middle of a project. Having a bulk pack on hand means you can change tips as soon as performance degrades, rather than trying to stretch the life of a worn tip and compromising your weld quality. Whether you are working on automotive restoration, light structural fabrication, or general repairs, the Tweco 14T-30 delivers the consistent performance professional welders demand.
