KP3162-4B1 - Lincoln Electric Extended Life Subarc Contact Tip, 5/32 in (10-Pack)

Keep Your Arc Running Longer

Every welder knows that downtime kills productivity, especially when you are in the middle of a long run on a heavy plate. The Lincoln Electric KP3162-4B1 Extended Life Contact Tip is built to keep you welding and stop you from constantly swapping out burned-up tips. Designed for 5/32-inch wire, these tips are the workhorses of the submerged arc world. Whether you are running a tractor or a manipulator, you need a tip that can handle the heat without fusing to the wire or keyholing out after just a few passes. These tips are made to withstand the punishment of high-amperage subarc welding so you can focus on the bead, not the maintenance.

Built Tougher Than Standard Copper

Standard copper tips are fine for light MIG work, but when you are pouring on the amps in a subarc setup, they just don't last. That is why Lincoln Electric makes these tips out of a special Copper Chrome Zirconium alloy. This material is harder and handles heat much better than plain copper. What does that mean for you? It means the tip stays true longer. The hole doesn't wear out into an oval shape as fast, which keeps your wire aimed exactly where you want it. It also resists spatter adhesion and burnback better, giving you a smoother, more consistent feed. When your contact tip lasts longer, your arc stays stable, and your weld quality goes up.

Perfect Fit for K231 Torches

These tips are direct replacements for the Lincoln K231-1 and K231-2 torches. You don't have to worry about fitment issues or bad connections that lead to arcing inside the gun. They screw in tight and transfer current efficiently. Sold in a convenient 10-pack, you can toss a box in your gang box or keep them at the station so you are always ready to go. If you are tired of tips that soften up and fail halfway through a shift, upgrade to the Extended Life KP3162-4B1 and see the difference a better alloy makes in your daily production.
