KP2745-116R-B100 - Lincoln Electric Magnum PRO Copper Plus Contact Tip 550A 1/16in (100 Pack)

Keep Your Arc Stable and Your Line Moving

Every welder knows the frustration of a contact tip failing right in the middle of a critical pass. The arc starts to stutter, the wire burns back, and suddenly you are grinding out a defect instead of laying down metal. The Lincoln Electric Magnum® PRO Copper Plus® Contact Tips (KP2745-116R-B100) are built to solve exactly that problem. Designed for heavy-duty welding with 1/16 inch (1.6 mm) wire, these tips are not your average consumables—they are engineered to withstand the punishment of 550A welding without giving up.

The secret lies in Lincoln's Copper Plus® technology. Unlike standard tips that soften and wear out quickly when things get hot, these tips are made from a special alloy that stays harder and runs cooler. This means the hole at the end of the tip keeps its shape longer, preventing the dreaded "keyholing" that ruins your aim and your electrical contact. For you, this translates to a smoother, more consistent arc that goes exactly where you point it, hour after hour.

This 100-pack bulk option is perfect for busy shops that can't afford to run out of parts. Whether you are running a robotic cell that welds 24/7 or a team of fabricators pushing high-deposition wire, having a reliable supply of premium tips means less downtime spent walking to the tool crib and more time making sparks. The tips are designed to fit seamlessly with your Magnum PRO guns, screwing in tight and staying put.

Stop settling for cheap tips that need changing every few hours. Upgrade to the Magnum PRO Copper Plus series and experience the difference that quality materials make. With better heat dissipation and a longer service life, these tips help you maintain high-quality welds while reducing the frequency of consumable changes. It’s a small upgrade that makes a big difference in your daily productivity and weld consistency.
