KP2217-3B1 - Lincoln Electric 3/64" Heavy Duty Aluminum Contact Tip (25-Pack)

Smooth Aluminum Welding with Lincoln KP2217-3B1

If you have ever struggled with aluminum MIG welding, you know the frustration of burnbacks, erratic feeding, and the dreaded bird-nesting at the feeder. Often, these issues stem from using a generic contact tip that isn't designed for the job. The Lincoln Electric KP2217-3B1 Heavy Duty Contact Tip is your solution for running 3/64-inch 5356 aluminum wire. Unlike standard steel tips, these are built with the specific properties of aluminum in mind, giving you a smoother, more reliable welding experience.

Aluminum wire expands significantly as it heats up. If your tip is too tight, the wire grabs and jams. If it's too loose, you lose electrical contact and the arc sputters. Lincoln Electric has engineered these tips with the perfect clearance for 5356 alloy, which is slightly stiffer than 4043 but still demands precise handling. The heavy-duty design means the tip stays cooler longer, resisting the deformation that often happens when you are pushing high amps on thick aluminum plate. This translates to fewer tip changes and more time under the hood laying down beads.

This pack contains 25 contact tips, ensuring you have plenty of stock for big projects. Whether you are fabricating boat hulls, trailers, or custom aluminum structures, using the right consumable is the cheapest insurance against bad welds. Swap out your old, worn tips for these specialized Lincoln Electric units and notice the difference in your arc stability immediately. Keep your production line moving and your welds clean with consumables that are built for the specific demands of aluminum fabrication.
