OVERVIEW

Reliable Performance with Tweco 14-40 Tips

Every welder knows that the contact tip is the final transfer point for welding current, and its quality directly impacts your arc stability. The Tweco 14-40 contact tip is the industry standard for a reason. Designed for 0.040" (1.0mm) wire, these tips are built to handle the heat of daily fabrication work while delivering a smooth, consistent arc. Whether you are running a Tweco #2, #3, or #4 gun, these tips drop right in and get you back to welding.

Cheap generic tips often suffer from poor bore concentricity or inferior copper alloys, leading to wandering arcs, frequent burn-backs, and frustrating downtime. Genuine Tweco tips are machined to strict standards, ensuring the wire slides through smoothly while maintaining the electrical contact needed for a crisp weld. The copper alloy resists spatter adhesion and withstands the thermal cycles of start-stop welding better than budget alternatives.

This 25-pack is perfect for busy shops or mobile rigs. Running out of tips in the middle of a job is a hassle you don't need. By keeping a box of 14-40s on hand, you ensure that you can swap out a worn tip instantly and keep your production line moving. Upgrade your consumables to genuine Tweco and experience the difference in your weld bead consistency and overall gun performance.

FAQ

The 14-40 tip is designed for 0.040-inch (1.0mm) welding wire.

These tips fit Tweco Professional Series No. 2, No. 3, and No. 4 guns, as well as Spray Master series guns using 14 Series consumables.

The thread size is standard 1/4"-28 UNF.

This package contains 25 individual contact tips.

The 14 Series is considered the standard duty tip for Tweco guns. For higher amperage applications, heavy-duty variants (14H series) may be available, but the standard 14-40 is robust enough for most general fabrication.

While physically possible if the size matches, aluminum wire typically requires slightly oversized tips (often marked with an 'A') to accommodate thermal expansion. The 14-40 is primarily for steel and stainless steel wire.
