KP15HFC-564 - Lincoln Electric 5/64" Heavy Duty Flux-Core Contact Tip (10-Pack)

Burn Heavy Wire Without the Burnout

When you are running 5/64" flux-cored wire, you aren't messing around with sheet metal—you are likely welding heavy plate, structural beams, or heavy machinery. For that kind of work, you need a contact tip that can take the heat. The Lincoln Electric KP15HFC-564 is built exactly for that. This isn't your standard light-duty MIG tip; it is a 500-Amp Heavy Duty beast designed to stand up to the high heat and aggressive nature of large-diameter flux-core welding.

We all know the frustration of a tip that seizes up halfway through a pass or keyholes out so bad your arc starts wandering all over the joint. The 'FC' in the part number stands for Flux Core, meaning the bore is sized just right to let that cored wire slide through smoothly while still making solid electrical contact. This reduces drag and prevents the wire from shaving inside the tip, which is a common cause of bird-nesting at the drive rolls. The heavy-duty copper construction keeps the tip cooler for longer, meaning you spend less time swapping out parts and more time laying down metal.

These tips come in a convenient 10-pack, so you can keep a handful in your toolbox or at your station. Whether you are pushing a Magnum gun or a compatible setup, these tips thread in securely and give you the consistent performance you expect from Lincoln. Don't let a cheap tip ruin a critical weld; stick with the heavy-duty KP15HFC-564 for your heavy wire applications.
