The Tweco Style 14H-116 Contact Tip is a premium aftermarket replacement designed to meet the rigorous demands of heavy industrial welding. Engineered for durability and precision, this contact tip is an essential consumable for welders using 1/16-inch (1.6mm) wire in high-amperage applications. Whether you are fabricating structural steel, working on heavy machinery, or performing general repairs, the 14H-116 ensures consistent wire feeding and arc stability.
This "Heavy Duty" (14H) series tip is constructed with a thicker wall compared to standard duty tips, allowing it to withstand higher heat and current loads up to 400 amps. The robust copper alloy construction provides excellent thermal and electrical conductivity, reducing the risk of burn-back and extending the lifespan of the consumable. By maintaining a cooler operating temperature, these tips help minimize downtime associated with frequent tip changes.
Compatibility is a key feature of the GEN14H-116. It is designed to fit a wide range of industry-standard MIG guns, including Tweco® No. 2, No. 3, and No. 4 series guns. Additionally, it is fully compatible with Lincoln Electric® Magnum® 250, 300, and 400 amp guns. This versatility makes it a smart inventory choice for shops that utilize multiple gun models. The threaded base ensures a tight, secure connection to the gas diffuser, preventing gas leaks and ensuring maximum current transfer to the welding wire.
Each tip is precision-machined with an inside diameter tolerance held to +/- .003 inches. This tight tolerance reduces micro-arcing inside the tip and ensures smooth wire delivery, which is critical for producing high-quality welds. The tips are also clearly marked with the part number and wire diameter for quick and easy identification in a busy workshop environment. Sold typically in packs of 25, these contact tips offer professional-grade performance at an exceptional value.
