11501259 - Tweco 15HFC-564 Heavy Duty Contact Tip 5/64" (25 Pack)

Tweco 15HFC-564 Heavy Duty Contact Tip (5/64") - 25 Pack

The Tweco 15HFC-564 is a premium heavy-duty contact tip designed specifically for industrial welding applications utilizing 5/64-inch (2.0 mm) wire. Part of the renowned Tweco 15HFC series, these tips are engineered to handle high amperage and the intense heat generated during heavy fabrication and flux-cored arc welding (FCAW). The "HFC" designation typically points to a design optimized for heavy-duty flux core applications, featuring a robust outer diameter and substantial copper mass to effectively dissipate heat and prolong the service life of the consumable.

Precision manufacturing is at the core of the 1150-1259 SKU. Each tip features a strictly controlled bore tolerance that ensures optimal electrical conductivity between the contact tip and the welding wire. This consistent electrical transfer is critical for maintaining a stable arc, reducing micro-arcing inside the tip, and preventing premature burn-back. The copper alloy construction provides an excellent balance of conductivity and hardness, resisting the abrasive wear caused by the continuous feeding of heavy wire.

These contact tips are designed to fit standard Tweco heavy-duty gas diffusers found on higher amperage MIG guns. They are an essential component for fabricators working on structural steel, heavy equipment repair, or shipbuilding where 5/64" wire is a standard consumable. Supplied in a package of 25, this SKU ensures that maintenance teams and operators have a ready supply of critical spares, minimizing downtime on the production floor. Whether running gas-shielded flux core or self-shielded wires, the 15HFC-564 delivers the reliability professionals expect from Tweco.
