14H-564 - Tweco Style 14H-564 Contact Tip - .035" - Heavy Duty (25-Pack)

Heavy-Duty Contact Tip for High-Amperage MIG Welding

The Tweco Style 14H-564 Contact Tip is a premium consumable designed for heavy-duty MIG welding applications. Engineered to withstand currents up to 400 amperes, this contact tip is an essential component for welders requiring consistent performance in demanding industrial environments. It is specifically manufactured to fit Tweco 52 and 52F gas diffusers, ensuring seamless compatibility with standard heavy-duty MIG gun setups.

Constructed from high-grade copper alloy tubing, the 14H-564 offers superior electrical conductivity and thermal transfer properties. The manufacturing process involves precise machining to achieve a consistent inside diameter with a tolerance held to +/-.003 inches. This tight tolerance is critical for maintaining a stable arc and ensuring smooth wire feeding, reducing the risk of micro-arcing inside the tip which can lead to premature failure. The tip features a threaded design that secures firmly into the gas diffuser, optimizing the electrical connection and gas coverage.

Each tip is clearly marked with its part number and wire diameter, allowing for quick identification on the shop floor. This pack contains 25 contact tips, providing a cost-effective solution for high-volume welding operations. Whether used in fabrication, structural steel, or heavy equipment repair, the 14H-564 delivers the durability and precision professional welders expect.
