11501268 - Tweco WeldSkill 15 Series Contact Tip, 1/16 in (1.6mm) - 25 Pack

Technical Overview of Tweco WeldSkill WS15HFC116 Contact Tips

The Tweco WeldSkill WS15HFC116 is a specialized contact tip designed for industrial welding applications utilizing 1/16-inch (1.6mm) diameter wire. As a critical component in the Gas Metal Arc Welding (GMAW) and Flux-Cored Arc Welding (FCAW) processes, this contact tip is engineered to facilitate precise current transfer from the welding gun to the electrode wire. It is manufactured to strict tolerances, ensuring that the internal bore diameter provides the optimal clearance for 1/16" wire, minimizing friction while maintaining constant electrical contact.

Part of the renowned Tweco WeldSkill line, the WS15HFC116 belongs to the 15 Series family of consumables. This series is widely recognized for its compatibility with a broad range of Tweco MIG guns, particularly those used in medium-to-heavy fabrication environments. The tip is constructed from a high-quality copper alloy, selected for its superior thermal and electrical conductivity properties. This material choice is essential for managing the resistive heating generated at the contact point, thereby extending the service life of the tip and preventing premature failure modes such as keyholing or fusion to the wire.

The "HFC" designation in the part number often correlates with heavy-duty or flux-cored applications where larger diameter wires like 1/16" are standard. In these high-amperage scenarios, the integrity of the contact tip is paramount to maintaining a stable arc. A worn or ovalized tip can lead to erratic arc wandering and poor weld bead morphology. By utilizing genuine Tweco WeldSkill tips, operators ensure that the concentricity of the wire exit is maintained, promoting accurate targeting in the weld joint.

This product is supplied in a package of 25 units. Bulk packaging is particularly advantageous for industrial MRO (Maintenance, Repair, and Operations) procurement, as contact tips are consumable items that require regular replacement to maintain weld quality. The threaded base of the tip allows for quick and secure installation into the gas diffuser, ensuring a tight electrical connection and efficient gas coverage when used with a nozzle.
