Tweco 1140-1341 (WS14T30) Contact Tips: Precision and Value

The Tweco 1140-1341, also known by the model number WS14T30, is a standard copper contact tip designed for general purpose MIG welding applications. This product comes in a cost-effective package of 25, making it an ideal choice for industrial environments where consumable turnover is high. These tips are machined to accommodate .030-inch (0.8mm) solid or flux-cored welding wires, providing the essential electrical connection required for Short Circuit, Globular, or Spray Transfer modes.

As part of the Tweco 14 Series family, these contact tips feature the industry-standard form factor used in Tweco WeldSkill, Mini-MIG, and Tweco #1 MIG guns (up to 180-220 amps). The tip features a 1/4"-28 UNF thread for universal compatibility with standard 14-series gas diffusers. The copper construction is optimized for thermal conductivity, helping to dissipate heat generated at the arc zone while maintaining the structural integrity of the tip bore. This reduces the frequency of "keyholing"—where the exit hole becomes oval-shaped—which is a primary cause of wandering arcs and poor bead placement.

Technical Specifications & Benefits

Professional welders understand that the contact tip is a wear item that directly influences weld quality. The Tweco WS14T30 offers:

• Consistent Bore Diameter: Precision drilling ensures the wire slides through with minimal friction while maintaining constant electrical contact.
• Thermal Durability: High-grade copper alloy resists annealing and deformation under normal duty cycles.
• Secure Threading: The 1/4"-28 threads prevent loosening due to vibration, ensuring the gas diffuser and tip remain electrically coupled.

This 25-pack configuration is specifically tailored for high-volume users who require reliable inventory management. By stocking the 1140-1341, fabrication shops can ensure their welders have immediate access to replacement parts, minimizing downtime associated with troubleshooting feed issues caused by worn tips. Whether used in a production line or a job shop, these Tweco contact tips deliver the performance expected from a leader in arc welding accessories.
