11401170 - Tweco WS14-52 Contact Tip 0.052 Inch (25 Pack)

Technical Overview of Tweco WeldSkill WS14-52 Contact Tips

The Tweco WeldSkill WS14-52 Contact Tip (SKU: 1140-1170) is a critical consumable component designed for use with Gas Metal Arc Welding (GMAW) and Flux Cored Arc Welding (FCAW) processes. Engineered to accommodate 0.052-inch (1.3mm) welding wire, this contact tip belongs to the industry-standard Tweco 14 Series family. It features a precise internal bore tolerance that facilitates optimal electrical transfer from the welding power source to the electrode wire, a fundamental requirement for maintaining a stable and consistent arc.

Constructed from a high-quality copper alloy, the WS14-52 provides excellent thermal and electrical conductivity. This material selection helps dissipate the intense heat generated at the contact point, thereby prolonging the service life of the tip and reducing the frequency of burn-backs. The tip measures 1.5 inches (38.1mm) in length with an outside diameter of 0.375 inches (9.5mm), making it compatible with a vast array of MIG guns, including the Tweco Classic No. 2, No. 3, and No. 4 series, as well as the Tweco WeldSkill gun line. The threaded base utilizes a standard 1/4"-28 UNF pitch, ensuring a secure mechanical and electrical connection to the gas diffuser.

In industrial MRO environments, the consistency of consumables is paramount. The WeldSkill line is manufactured to strict tolerances to prevent issues such as micro-arcing inside the tip or erratic wire feeding caused by bore irregularities. By maintaining a consistent contact patch with the wire, the WS14-52 minimizes voltage drops and resistance heating. This 25-pack configuration is specifically tailored for fabrication shops and maintenance departments that require a reliable inventory of consumables for 0.052" wire applications, often used in structural steel and heavy fabrication settings.
