11401301 - Tweco 14T-30 Contact Tip 0.030-Inch (Pack of 25)

Reliable Performance with Tweco 14T-30 Contact Tips

For industrial fabrication shops and professional welders, consistency is key. The Tweco 14T-30 Contact Tip (Part Number 1140-1301) is the industry standard for 0.030-inch (0.8mm) welding wire applications. Designed to fit the ubiquitous Tweco No. 2, No. 3, and No. 4 MIG guns, as well as the Spray Master series, these tips are a staple in manufacturing environments across North America. This package contains 25 genuine Tweco contact tips, ensuring your shop remains stocked and downtime is minimized.

Precision Engineering for Stable Arcs

The contact tip is the final point of electrical transfer to the welding wire, making its quality critical for arc stability. Tweco manufactures the 14T-30 using a high-grade copper alloy that offers an optimal balance of electrical conductivity and wear resistance. The bore is precision-drilled to tight tolerances, ensuring the 0.030" wire feeds smoothly without excessive play. This tight tolerance reduces micro-arcing inside the tip, which is a common cause of burn-back and premature tip failure. By maintaining a consistent electrical connection, these tips help produce cleaner welds with less spatter.

Standard Duty 14 Series Compatibility

The "14 Series" designation refers to the physical dimensions and threading of the tip, which utilizes a standard 1/4"-28 UNF thread. This makes the 14T-30 compatible with a vast array of gas diffusers, including the standard 52 and 52-23 series diffusers found on classic Tweco guns. Whether you are running a manual MIG setup or a semi-automatic production line, these standard-duty tips provide the reliability needed for mild steel and stainless steel applications.

Optimized for Production

In high-volume welding operations, consumable changeovers are inevitable. However, using inferior generic tips can lead to frequent stoppages due to wire jamming or erratic arcs. Genuine Tweco consumables are manufactured to strict quality control standards to ensure every tip in the box performs identically. The 25-pack configuration is designed for the professional user, offering better value and inventory control for busy workshops.
