11101342 - Tweco WS11T35 0.035" MIG Contact Tips (Pack of 25)

Technical Overview of Tweco WeldSkill WS11T35

The Tweco WeldSkill WS11T35 is a standard duty contact tip designed for use with 0.035-inch (0.9mm) solid or flux-cored welding wires. Part of the renowned Tweco 11-Series, these tips are engineered to fit a broad spectrum of light-to-medium duty MIG guns, including the Tweco Mini-MIG, WeldSkill, and legacy No. 1 and No. 2 series torches. The tips are manufactured from a high-quality copper alloy that balances hardness with electrical conductivity, ensuring efficient current transfer to the welding wire while resisting the heat generated at the contact point.

Each tip features a precision-drilled bore with tight tolerances to minimize micro-arcing inside the tip, which can lead to burn-back and irregular wire feeding. The exterior is machined with standard 1/4"-28 UNF threads, allowing for quick and secure attachment to compatible gas diffusers (such as the 51 series). This bulk package contains 25 individual contact tips, making it an ideal inventory item for fabrication shops and industrial maintenance departments requiring consistent consumable replacements.

The WS11T35 adheres to Tweco's strict manufacturing standards, providing a reliable electrical connection that promotes stable arc characteristics. The tip length and geometry are optimized to maintain proper stick-out and gas coverage when used with standard Tweco nozzles. These consumables are essential for maintaining the performance of Tweco MIG systems in automotive, general fabrication, and hobbyist applications.
