OVERVIEW

Genuine Tweco 14T-30 Contact Tips (25-Pack)

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.

Why Choose Genuine Tweco?

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.

Universal Fit for Tweco Style Guns

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.

Value and Convenience

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.

  • Restores arc stability and wire feed smoothness.
  • Direct replacement for worn 0.030" tips on Tweco guns.
  • Standard duty design ideal for most shop applications.
  • Pack of 25 provides excellent value per tip.

FAQ

The 14T-30 is designed specifically for 0.030" (0.8mm) welding wire.

These tips fit Tweco Classic No. 2, No. 3, and No. 4 guns, as well as Tweco Spray Master 250, 350, and 450 guns. They also fit many other brands that use Tweco 14-series style consumables.

The thread size is the standard 1/4"-28 UNF.

No, the "T" in 14T-30 stands for Standard Duty. For heavy-duty applications, Tweco offers the 14H series, though the 14T is sufficient for most standard amperage ranges.

This SKU (11401301) contains a package of 25 contact tips.

They are generally the same; "14T" designates the standard Tweco design. Some older nomenclatures might just say 14-30, but 1140-1301 is the current part number for the standard duty version.

While physically possible if the size matches, aluminum wire usually requires a slightly oversized tip (e.g., using a 0.035" tip for 0.030" aluminum wire) due to thermal expansion. Specific aluminum tips (14A series) are recommended for best results.
