Welding is all about the details, and nothing ruins a good bead faster than a worn-out contact tip. The Tweco 11-45 Contact Tip (WS1145) is the genuine replacement part you need to keep your Tweco WeldSkill or Mini-MIG gun running smoothly. Designed for 0.045" wire, these tips are engineered to handle the heat and current of your MIG welding projects, providing a clean, consistent electrical connection to your filler metal.
Why choose genuine Tweco? It comes down to fit and finish. Cheap aftermarket tips often have inconsistent bore sizes that cause wire drag or erratic arcs. These 11-series tips are machined to precise tolerances, ensuring your wire feeds smoothly without wandering. The copper construction effectively dissipates heat, extending the life of the tip even when you are pushing your machine's duty cycle. They screw easily into any standard Tweco gas diffuser with 1/4"-28 threads, making changeovers quick and frustration-free.
This 25-pack is the smart buy for any welder. Contact tips are consumables—they wear out, get clogged with spatter, or fuse during burn-backs. Buying in bulk means you save money per tip and never have to stop a job because you ran out of parts. Whether you are a hobbyist tackling a big project or a professional fabricator, stocking up on the 1110-1144 tips ensures you are always ready to lay down perfect welds.
