11401243 - Tweco WS14H-40 Heavy Duty Contact Tip 0.040 (25 Pack)

Reliable Performance with Tweco WeldSkill Contact Tips

Keep your MIG welding operations running smoothly with the Tweco WeldSkill WS14H-40 Contact Tip. Designed for welders who demand consistency and durability, this heavy-duty tip is built to handle the heat. If you are running 0.040-inch (1.0mm) wire, this is the essential consumable you need to maintain a stable arc and produce high-quality welds. The contact tip is the unsung hero of your MIG gun, transferring the power directly to the wire; a worn or inferior tip can lead to frustration, burn-backs, and poor weld appearance. Tweco's WeldSkill line ensures you get professional-grade reliability without breaking the bank.

The WS14H-40 stands out because of its heavy-duty construction. The extra copper material provides better heat dissipation compared to standard tips, meaning it stays cooler longer. This is crucial during long welds or when pushing your machine's duty cycle, as it prevents the tip from overheating and fusing to the wire. The precision-drilled bore ensures that your wire feeds smoothly, reducing the micro-arcing inside the tip that causes premature wear. Whether you are working in a production shop, a garage, or on a job site, having a fresh pack of these tips ensures you are always ready to lay down a perfect bead.

This pack contains 25 contact tips, giving you plenty of backup for big projects. They feature the industry-standard Tweco 14-series thread (1/4"-28), making them compatible with a vast range of MIG guns, including the classic Tweco No. 1, 2, and 4, as well as many other Tweco-style guns on the market. Swapping them out is quick and easy, allowing you to minimize downtime and get back to welding. Don't let a worn-out tip compromise your work; upgrade to the heavy-duty WS14H-40 and experience the difference in arc stability and feed performance.
