11101203 - Tweco 11-40 Contact Tip 0.040-Inch (25 Pack)

Reliable Performance with Tweco 11-40 Contact 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 the wire, and its condition directly dictates the stability of your arc. The Tweco 11-40 Standard Contact Tip is designed to keep that arc crisp, consistent, and reliable. If you are running 0.040" (1.0mm) wire, these tips are the exact match you need to prevent the frustration of burn-backs, stuttering wire feeds, and wandering arcs that come with using worn-out or incorrectly sized consumables.

Tweco has long been the industry standard for MIG components, and their 11 Series tips are no exception. Made from high-grade copper, they resist overheating and maintain their shape even during long beads. The precision-drilled bore ensures that the wire slides through smoothly while maintaining constant electrical contact. This means less spatter and better bead profile for you. Whether you are working on automotive repairs, light fabrication, or hobbyist projects with a Tweco #1 or Mini-MIG style gun, these tips deliver the professional performance you expect from the brand.

Why Buy the 25-Pack?
Contact tips are consumables—they wear out. As the wire passes through, it slowly erodes the copper bore, turning an oval hole into a keyhole shape. This loss of contact causes voltage drops and erratic welding. By stocking up with this 25-pack (SKU: 11101203), you ensure you always have a fresh tip on hand. There is nothing worse than having to stop a job because you blew your last tip. With this pack in your toolbox, you can swap out a worn tip the moment you notice performance degrading, keeping your welds high-quality and your downtime near zero.

These tips feature the standard 1/4"-28 thread, making them easy to screw into your gas diffuser. They are built to handle the heat and current of day-to-day welding. Don't compromise your weld quality with generic, poorly machined knock-offs. Stick with genuine Tweco 11-40 tips for your 0.040" wire applications and experience the difference that quality consumables make in your daily work.
