11101304 - Tweco 11T-45 Contact Tip 0.045 (Pack of 25)

Reliable Arc Performance with Tweco 11T-45 Tips

Achieving a high-quality weld starts with the condition of your consumables, and the contact tip is arguably the most critical component in the MIG welding circuit. The Tweco 11T-45 Contact Tip is designed to deliver superior current transfer and smooth wire feeding for 0.045-inch welding wire. Whether you are working on mild steel fabrication, repairs, or general maintenance, these genuine Tweco tips ensure that your welding arc remains stable and focused, reducing spatter and improving bead appearance.

This 25-pack of 11T-45 tips (SKU 1110-1304) is an economical choice for busy workshops. The 11 Series tips are the industry standard for light-duty MIG guns, commonly found on 100A to 180A welding systems. Their compact design allows for better visibility of the weld puddle and easier access into tight corners compared to larger, heavy-duty tips. Despite their small size, they are built with robust copper alloy to withstand the heat of the welding arc and resist the adhesion of spatter, although the use of nozzle dip or anti-spatter spray is always recommended to extend their service life further.

One of the common frustrations in MIG welding is "burnback," where the wire fuses to the tip, or an erratic arc caused by poor electrical contact. The Tweco 11T-45 addresses these issues with precise machining. The bore is concentric and smooth, minimizing friction as the wire passes through. This reduces drag on the wire feeder motor and ensures that the electrical current is transferred consistently to the wire as it exits the tip. The result is a crisp, sizzling arc that professionals recognize as the sign of a tuned-in machine.

Installation is quick and easy thanks to the standard threaded base. Simply unscrew the old, worn tip and thread in a new 11T-45 until it seats firmly against the diffuser. Keeping a bulk pack of 25 tips in your shop ensures that you never have to stop a project to run to the store for consumables. Trust in the reliability of Tweco, a brand synonymous with MIG welding excellence, to keep your production line moving and your welds holding strong.
