11401345 - Tweco WS14T52 Contact Tip 0.052 Inch - 25 Pack

Precision Tweco 14 Series Contact Tips – WS14T52

The Tweco 1140-1345 (WS14T52) Contact Tip is a premium consumable designed for MIG welding applications utilizing 0.052" (1.3mm) wire. Part of the WeldSkill family, these tips are manufactured to strict tolerances to ensure optimal electrical contact and wire feedability. The 14 Series form factor is one of the most widely used in the industry, making these tips a versatile choice for users of Tweco MIG guns, including the WeldSkill, Mini-MIG, and various Tweco-style aftermarket torches.

Technical Precision and Performance
The performance of a MIG gun is often dictated by the quality of its consumables. The WS14T52 features a precision-drilled internal bore that accommodates 0.052" wire with minimal friction while maintaining sufficient contact for electrical transfer. This balance is crucial; too tight, and the wire drags; too loose, and the arc becomes unstable due to poor conductivity. Tweco's manufacturing process ensures that every tip in this 25-pack meets rigorous standards, preventing the micro-arcing inside the tip that leads to premature failure.

Material and Construction
Crafted from a high-grade copper alloy, these tips are designed to dissipate heat effectively. In high-amperage applications often associated with 0.052" wire, heat buildup can cause softer tips to deform or melt, fusing the wire to the tip (burn-back). The superior thermal properties of the WeldSkill copper alloy resist this deformation, maintaining the tip's structural integrity over longer periods. The standard 1/4"-28 UNF threads ensure a secure, vibration-resistant connection to the gas diffuser, further enhancing current transfer efficiency.

Application and Value
This 25-pack configuration is ideal for industrial settings where throughput is critical. Regular replacement of contact tips is vital for maintaining weld quality, as worn tips can lead to wandering arcs and poor bead profiles. By choosing genuine Tweco WeldSkill tips, you ensure compatibility and performance that meets the demands of professional welding. Whether you are welding mild steel, stainless, or flux-cored applications, equip your MIG gun with the WS14T52 to experience smoother feeding, superior arc control, and the reliability that comes with the Tweco name.
