11501209 - Tweco 15H-564 Contact Tip 5/64-Inch (Pack of 25)

Reliable Arc Performance with Tweco 15H-564 Tips

When you are pushing high amps and laying down heavy beads with 5/64" wire, your contact tip is the most critical link in the electrical circuit. The Tweco 15H-564 contact tip is built to handle the heat. Designed for the heavy hitters—the Tweco No. 5 and No. 6 MIG guns—this tip features the substantial 15-series body that professionals trust for structural and heavy fabrication work. Unlike smaller tips that overheat and fuse quickly, the 15H-564 utilizes a larger mass of copper and a heavy-duty 3/8" thread to dissipate heat effectively, keeping your production line moving.

Welders know that a worn contact tip causes erratic arcs, wandering wire, and frustrating burn-backs. This pack of 25 ensures you always have a fresh tip on hand to maintain peak performance. The bore of the 15H-564 is machined specifically for 5/64" (2.0 mm) wire, providing the perfect balance between feedability and electrical contact. Too tight, and the wire drags; too loose, and the arc stutters. Tweco's precision manufacturing hits the sweet spot, giving you a smooth, buttery arc that makes long welds easier to manage.

These tips are particularly well-suited for flux-cored arc welding (FCAW) and heavy MIG applications where deposition rates are high. The copper alloy construction resists spatter adhesion better than inferior generic alternatives, and the threads are cut cleanly to ensure they seat fully into the gas diffuser every time. A loose tip is a hot tip, and a hot tip fails; Tweco's engineering ensures a secure fit that maximizes current transfer directly to the wire.

Don't let poor consumables compromise your weld quality. Upgrading to genuine Tweco 15H-564 tips means fewer tip changes, less troubleshooting, and more arc-on time. Whether you are welding thick plate in a shipyard or fabricating heavy machinery, these tips deliver the consistency you need to pass X-ray and ultrasound testing. Keep your toolbox stocked with this 25-pack and experience the difference that quality consumables make in high-amperage welding.
