11401214 - Tweco 14AH-116 Heavy Duty Aluminum Contact Tip (Pack of 25)

Premium Tweco 14AH-116 Contact Tips for Aluminum Welding

Maximize your welding performance with the Tweco 14AH-116 Contact Tip, specifically engineered for heavy-duty aluminum MIG welding applications. Sold in a convenient pack of 25, these contact tips are an essential consumable for professional fabricators and industrial workshops that demand consistency and reliability. As part of the renowned Tweco 14 Series, these tips are designed to fit industry-standard Tweco No. 2, No. 3, and No. 4 MIG guns, as well as many compatible aftermarket torches.

Welding with aluminum wire presents unique challenges compared to steel. Aluminum expands more when heated and is softer, making it prone to feeding issues and burn-backs if the contact tip bore is not precise. The "AH" designation in the 14AH-116 part number indicates a Heavy-Duty Aluminum design. These tips typically feature a slightly optimized bore tolerance to accommodate the thermal expansion of 1/16" (1.6mm) aluminum wire without seizing, ensuring smooth wire feeding and stable arc transfer.

Constructed from high-grade copper alloy, Tweco contact tips offer superior thermal conductivity and electrical transfer. This reduces heat buildup at the contact point, extending the life of the tip and preventing premature failure. For high-amperage applications, the heavy-duty wall thickness provides extra durability, allowing you to weld longer between tip changes. Whether you are manufacturing aluminum trailers, repairing boat hulls, or working on automotive components, using genuine Tweco consumables ensures your equipment operates at peak efficiency.

Key Benefits:

• Optimized for Aluminum: Designed to handle the specific feed characteristics and thermal expansion of aluminum wire.
• Heavy-Duty Construction: Thicker walls withstand higher heat and amperage, reducing downtime.
• Precision Machining: Smooth bore finish minimizes friction and micro-arcing inside the tip.
• Universal Compatibility: Fits a wide range of Tweco-style MIG guns found in shops worldwide.
