Tweco 1110-1141 WeldSkill Contact Tip (WS11-30) - 25 Pack

The Tweco 1110-1141 (also known as WS11-30) is a standard-duty copper contact tip designed for general purpose MIG welding applications using 0.030" (0.8mm) solid or flux-cored wires. Part of the WeldSkill line, these consumables deliver professional-grade performance at an economical price point, making them a preferred choice for fabrication shops, maintenance departments, and educational facilities. This SKU is supplied as a package of 25, providing excellent inventory management for high-volume welding stations.

Precision Engineering for Arc Stability
The primary function of the contact tip is to transfer welding current to the wire as it passes through the bore. The Tweco 11-30 features a precision-drilled bore with tight tolerances to ensure consistent electrical contact without excessive drag. The smooth internal finish minimizes micro-arcing inside the tip, which can lead to premature failure and wire jamming. The copper alloy construction is optimized for thermal conductivity, helping to keep the tip cooler during extended weld cycles and reducing the adhesion of spatter.

Compatibility and Specifications
These tips belong to the Tweco 11 Series family. They utilize a standard 1/4"-28 UNF thread for easy installation into compatible gas diffusers. They are the standard replacement tip for Tweco Mini-MIG guns, Tweco #1 guns, and numerous aftermarket MIG guns that follow the Tweco 11 Series architecture. The "30" in the part number designates the wire diameter compatibility (0.030"), ensuring the welder selects the correct size for their specific wire feed setup.
