OVERVIEW

Genuine Tweco 11-40 Contact Tips for .040" Wire

Ensure optimal performance in your MIG welding operations with genuine Tweco OEM Contact Tips. The 11-40 model is specifically engineered for use with .040" (1.0mm) welding wire, a common size for light-to-medium fabrication tasks. As part of the widely used 11 Series, these contact tips are the industry standard for versatility and reliability, fitting a vast range of MIG guns including the classic Tweco #1, #2, #3, and #4 models, as well as the Spray Master and Mini-MIG series.

Manufactured from high-quality copper alloy, these tips offer excellent thermal conductivity and electrical transfer. This results in a stable arc, reduced spatter, and consistent weld bead profiles. The precision-drilled bore minimizes friction while maintaining good electrical contact, preventing the common issues of micro-arcing and premature burn-back inside the tip. Whether you are welding mild steel, stainless, or aluminum, using OEM consumables ensures that your equipment operates as designed.

The 11-40 tip features a standard 1/4"-28 UNF thread, making it easy to install into standard gas diffusers (such as the 35-50 or 51 series). Regular replacement of contact tips is essential for maintaining weld quality, and choosing genuine Tweco parts guarantees that tolerances are exact. These tips are ideal for professional fabricators looking to maintain high productivity and minimize downtime caused by feeding issues.

FAQ

The Tweco 11-40 contact tip is designed specifically for .040" (1.0mm) welding wire.

These tips fit Tweco #1, #2, #3, and #4 series guns, as well as Spray Master, Mini-MIG, and any MIG gun that accepts standard Tweco 11 Series consumables.

Yes, these are genuine Tweco OEM contact tips, ensuring the highest quality and adherence to manufacturer specifications.

The tip features a standard 1/4"-28 UNF thread, which fits standard Tweco gas diffusers like the 35-50 or 51 series.

You should replace the tip if the bore becomes oval-shaped (keyholing), if spatter blocks the opening, or if you experience erratic arc and wire feeding issues.

While you can use standard copper tips for aluminum, it is often recommended to use tips specifically designed for aluminum (often marked with an 'A') due to thermal expansion, but for general use, the correct size copper tip will function.

The 11 series is the standard duty tip with a smaller outer diameter, while the 14 series is a heavy-duty tip with a larger outer diameter and more mass for higher heat applications.
