KP1962-1B1 - Lincoln Electric Severe Duty Subarc Contact Tip 1/8" (10-Pack)

Keep Your Subarc Running Longer

Every welder knows that submerged arc welding is all about deposition rates and keeping the arc on. When you are running long seams on heavy plate, the last thing you want to do is stop the carriage because your contact tip has worn out or fused. The Lincoln Electric KP1962-1B1 Severe Duty Contact Tip is built to solve exactly that problem. Designed for 1/8-inch (3.2 mm) wire, these tips are not your average copper consumables. They are made from a tough Beryllium-Copper alloy that stands up to the heat and abrasion of heavy-duty subarc welding much better than standard tips.

If you are running Lincoln K231-1 or K231-2 torches, these are the tips you need for your high-amperage work. Rated for 600 to 1200 amps, they can handle the heat without getting soft or keyholing prematurely. Keyholing causes the wire to wander and lose electrical contact, leading to a sputtering arc and potential weld defects. By switching to these Severe Duty tips, you ensure a smooth, consistent arc for longer periods. This means fewer tip changes per shift, less downtime for your machine, and more finished weld metal at the end of the day.

These tips come in a convenient 10-pack, so you can stock up your tool crib or keep a box right at the welding station. Whether you are welding bridge girders, pressure vessels, or heavy machinery, the reliability of your contact tip directly impacts your productivity. Don't let a cheap tip ruin a perfect run. Upgrade to the KP1962-1B1 and experience the difference that a high-quality, alloyed contact tip makes in your submerged arc operations. It’s a small part that makes a big difference in your daily efficiency.
