11601125 - Tweco 16FC-564 Flux Core Contact Tip, 5/64 Inch, 25-Pack

Reliable Tips for Heavy Flux Core Welding

When you are burning heavy flux-cored wire, you need a contact tip that can take the heat and keep the wire feeding smoothly. The Tweco 16FC-564 is built exactly for that purpose. Designed for 5/64" (2.0mm) flux-cored wire, these tips have the right bore tolerance to handle the rougher surface of cored wires without snagging or seizing up halfway through a pass. This pack of 25 ensures you have plenty of backups in your toolbox, so you aren't stuck waiting on parts when a tip finally wears out.

These tips fit the classic Tweco guns you likely already use—the No. 3, 4, 5, and 6 series. If you are running a heavy fabrication job, structural steel, or fixing heavy machinery, you know that standard solid-wire tips just don't last as long when pushing flux core. The "FC" series gives you that extra edge in durability and feed performance. The copper alloy is tough enough to withstand the high amperage and radiant heat typical of FCAW processes.

Don't let a worn-out tip ruin your arc stability or cause bird-nesting at the drive rolls. Swapping to a fresh 16FC-564 tip restores that crisp, consistent arc you need for passing X-ray quality welds. With the standard 3/8" thread, they screw right into your existing gas diffuser setup. Keep your gun running cool and your beads looking good with genuine-style consumables meant for the job.
