The Tweco 14-30 Contact Tip (Stock Code: 1140-1101) is the industry standard for medium-duty MIG welding applications. Designed to fit the widely used Tweco 14 Series platform, these contact tips are precision-machined from high-quality copper alloy to ensure optimal electrical conductivity and thermal transfer. This specific tip is sized for 0.030-inch (0.8mm) welding wire, providing the tight tolerance necessary for a stable arc and consistent weld bead profile.
These standard contact tips feature a 1/4"-28 UNF thread, making them compatible with a vast array of gas diffusers found in Tweco Classic Number 2, 3, and 4 MIG guns, as well as the Tweco Spray Master series. The 1.5-inch overall length and 0.345-inch outside diameter allow for excellent gas coverage when paired with standard nozzles. By maintaining a clean and precise contact point with the wire, the 14-30 tip minimizes micro-arcing inside the bore, which extends the life of the consumable and reduces downtime.
Supplied in a convenient package of 25, this SKU is ideal for industrial fabrication shops and manufacturing environments where consumable inventory management is critical. Whether you are welding mild steel, stainless, or aluminum, using genuine Tweco consumables ensures that your equipment operates at peak efficiency.
