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

Tweco 14AH-116 Heavy-Duty Contact Tips (25-Pack)

Equip your MIG torch with the Tweco 14AH-116 Contact Tip, the professional's choice for running 1/16-inch (1.6mm) aluminum welding wire. This package contains 25 heavy-duty contact tips, ensuring you have an ample supply for high-volume production environments. The 14 Series is one of the most popular consumable styles in the welding industry, known for its robust performance and ease of installation.

The 14AH-116 is distinct from standard steel tips. The "A" signifies its suitability for aluminum applications. Aluminum wire is softer and has a higher coefficient of thermal expansion than steel. A standard tip might cause the wire to bind as it heats up, leading to erratic feeding or "bird-nesting" at the drive rolls. These Tweco tips are manufactured with precise tolerances that allow for this expansion while maintaining excellent electrical contact for a stable, spatter-free arc. The "H" stands for Heavy Duty, meaning the tip has a larger outer diameter or thicker wall compared to standard duty tips, providing a greater heat sink capacity.

Technical Specifications:

• Part Number: 14AH-116 (Stock: 1140-1214)
• Wire Size: 1/16" (1.6 mm)
• Material: Copper Alloy
• Thread: 1/4"-28 UNF
• Type: Heavy Duty, Aluminum Specific

Installation is quick and secure thanks to the standard 1/4"-28 threads. These tips are compatible with standard gas diffusers used in Tweco #2 (200A), #3 (300A), and #4 (400A) air-cooled MIG guns. They also fit various robotic and automatic torches that utilize the 14 Series consumable system. By choosing genuine Tweco parts, you ensure that your contact tip concentricity is perfect, which is critical for aiming the arc exactly where you need it in the weld joint.

Maintaining a fresh contact tip is vital for weld quality. A worn tip can cause the arc to wander and increase electrical resistance. With this bulk pack of 25, you can afford to replace tips as soon as they show signs of wear, keeping your welds clean and your productivity high. Ideal for shipyards, truck body manufacturing, and general aluminum fabrication.
