11401205 - Tweco 14H-52 Heavy Duty Contact Tip .052 (Pack of 25)

Tweco 14H-52 Heavy Duty Contact Tip Overview

The Tweco 14H-52 Contact Tip (SKU: 1140-1205) is a premium consumable designed to meet the rigorous demands of industrial MIG welding. Part of the renowned Tweco 14 Series, this specific model is the "Heavy Duty" variant, denoted by the "H" in the part number. It is precision-engineered to accommodate .052-inch (1.3 mm) welding wire, a common diameter for structural and heavy fabrication applications. The tip features a standard 1/4"-28 UNF thread, making it universally compatible with a wide range of gas diffusers, including the Tweco 52, 52-23, and 54A series found in Tweco Classic No. 2, 3, 4, and 5 MIG guns.

Supplied in a package of 25, these contact tips are an essential stock item for workshops seeking to maintain consistent weld quality and reduce downtime. The heavy-duty construction involves a larger outer diameter compared to standard tips, providing a greater mass of copper alloy. This design enhancement significantly improves thermal conductivity, allowing the tip to dissipate heat more effectively during long weld cycles. By managing heat buildup, the 14H-52 reduces the risk of the wire fusing to the tip (burnback) and slows the rate of bore wear (keyholing), ensuring that electrical contact remains consistent over the life of the consumable.

Josef Gas provides these genuine Tweco components to ensure your equipment operates at peak efficiency. Whether you are running solid wire or flux-cored wires, the dimensional accuracy of the 14H-52 ensures smooth wire feeding and stable arc transfer. Investing in high-quality consumables like the Tweco 14H-52 is a cost-effective strategy to minimize troubleshooting and maximize production throughput in professional welding environments.
