KP14H-116-B100 - Lincoln Electric 1/16 Heavy Duty Contact Tips Bulk Pack

Keep Your Arc Smooth with Heavy Duty Tips

Every welder knows that the contact tip is the last point of contact between your machine and the arc, making it one of the most critical components in your MIG gun. When you are running heavy 1/16-inch wire, you are likely pushing serious amps and laying down a lot of metal. That kind of heat can chew up standard tips in no time. The Lincoln Electric KP14H-116-B100 Heavy Duty Contact Tips are built to take that punishment. With a thicker wall design than standard light-duty tips, these 14H series tips handle the heat better, resisting deformation and keyholing that can ruin your aim and your arc stability.

Designed specifically for the workhorses of the industry—the Magnum® 300 and Magnum® 400 MIG guns—these tips drop right into your existing setup. If you are tired of constant burn-backs or your wire dragging because the tip bore has worn out prematurely, upgrading to a fresh heavy-duty tip is the quickest fix. The 1/16-inch bore is machined precisely to let the wire feed smoothly while maintaining the electrical contact needed for a crisp, sizzling arc. Whether you are welding structural steel, heavy equipment, or thick plate, these tips help you maintain the consistency you need to pass inspection.

This 100-pack is the ultimate "peace of mind" for your shop. There is nothing worse than running out of tips in the middle of a rush job or on a late shift. With 100 tips in the box, you can stock up your tool crib, fill your personal stash, and keep the arc lit for weeks or months to come. Buying in bulk means you pay less per tip and spend less time ordering parts. Grab a pack of these Lincoln Electric heavy-duty tips and get back to what you do best—burning wire and making sparks.

Why Choose Heavy Duty?

When welding with larger diameter wires like 1/16", the resistive heat generated at the contact point is significant. Standard tips can overheat, soften, and fuse to the wire. These heavy-duty versions act as a better heat sink, keeping the contact area cooler and lasting longer. It’s a small upgrade that makes a big difference in your daily welding experience.
