11401206 - Tweco 14H-116 Heavy Duty Contact Tip 1/16" (25 Pack)

Tweco 14H-116 Heavy Duty Contact Tip (1/16") - 25 Pack

The Tweco 14H-116 is a premium heavy-duty contact tip designed for industrial MIG welding applications utilizing 1/16-inch (1.6mm) wire. Part of the widely used 14 Series, this consumable is engineered to fit Tweco Professional Number 2, 3, and 4 MIG guns, as well as the Spray Master series. The 'H' designation indicates a heavy-duty construction, featuring a thicker outer wall compared to standard 14 series tips. This increased mass improves heat dissipation, reducing the operating temperature of the tip and extending its service life in high-duty cycle environments.

Manufactured from high-quality copper alloy, the 1140-1206 contact tip ensures consistent electrical transfer from the diffuser to the welding wire. The bore is precision-drilled to strict tolerances to minimize friction while maintaining excellent electrical contact, which is critical for arc stability and preventing micro-arcing inside the tip. The threaded base utilizes a standard 1/4"-28 UNF thread, ensuring compatibility with standard Tweco gas diffusers (such as the 52 and 54 series). This pack contains 25 individual contact tips, making it an economical choice for fabrication shops and manufacturing facilities requiring reliable, continuous operation.

Technical specifications include a wire diameter compatibility of 0.062 inches (1.6mm), an overall length of approximately 1.5 inches, and a robust design suitable for both mixed gas and CO2 shielding gas applications. The tip is an essential component for maintaining the efficiency of the MIG gun assembly, directly influencing weld quality and downtime.
