OVERVIEW

Reliable Performance with Tweco 11-40 Tips

Every welder knows that the contact tip is the unsung hero of the MIG gun. It is the final point of contact where the welding power is transferred to your wire, and its condition directly dictates the quality of your arc. If you are running .040" (1.0mm) wire, the Tweco 11-40 Standard Contact Tip is the exact replacement you need to keep your beads smooth and your spatter low. Worn-out tips are the number one cause of erratic feeding, wandering arcs, and frustrating burnbacks. By keeping a fresh 11-40 tip in your gun, you ensure that the electrical connection remains solid, giving you that crisp, frying-bacon sound that indicates a perfectly tuned machine.

This package contains 25 high-quality copper contact tips, making it an essential addition to your shop's inventory. Running out of tips in the middle of a project is a headache no one needs; with this bulk pack, you can swap out tips the moment you notice performance degrading, rather than trying to squeeze a few more inches of weld out of a keyholed tip. These tips are designed to fit standard Tweco #1 and similar MIG guns, featuring the common 1/4"-28 thread that screws easily into your gas diffuser. The 1-inch length is the standard size for the 11 Series, providing the right balance of reach and gas coverage.

Whether you are fabricating light gauge steel, doing automotive bodywork, or performing general repairs, using the correct tip size is non-negotiable. Using a tip that is too large for your wire causes the arc to wander, while a tip that is too small will jam. These 11-40 tips are precision-drilled specifically for .040" wire, ensuring smooth feeding and consistent electrical contact. Upgrade your consumables management with this 25-pack and spend less time troubleshooting your gun and more time laying down quality welds.

FAQ

This contact tip is designed specifically for .040 inch (1.0 mm) welding wire.

This package contains 25 individual contact tips.

The tip features a standard 1/4"-28 UNF thread.

These tips generally fit Tweco #1, Tweco #2, Mini-MIG, and other guns that utilize the 11 Series consumable system.

The Tweco 11-40 contact tip is 1.0 inch (25.4 mm) in length.

As the wire passes through the tip, it wears the hole into an oval shape (keyholing), which causes poor electrical contact and an unstable arc.

The 11 Series is typically considered a standard-duty tip suitable for light to medium amperage applications. For higher heat applications, heavy-duty variants (like the 14 Series) are often used if the gun supports them.
