KP14H-35-B100 - Lincoln Electric Magnum Heavy Duty Contact Tip .035 (100-Pack)

Reliable Arc Performance for Professional Welders

As a welder, you know that the contact tip is the final transfer point for your welding current, and its condition directly dictates the quality of your arc. The Lincoln Electric KP14H-35-B100 Heavy Duty Contact Tip is built to keep you welding longer with fewer interruptions. Designed for the Magnum® 200, 250L, 300, and 400 MIG guns, these tips are a step up from standard consumables. The "Heavy Duty" build means there is more material to absorb and dissipate heat. When you are running long beads or working at the upper amperage limits of your machine, standard tips can overheat, soften, and keyhole, leading to an erratic arc and wire burnback. These heavy-duty tips resist that thermal breakdown, maintaining a crisp, consistent arc that lets you focus on your puddle control rather than troubleshooting your gun.

The .035-inch (0.9 mm) size is one of the most common wire diameters for general fabrication, automotive work, and light structural steel. Because this is a bulk pack of 100, you can keep a fresh supply right at your station or in your toolbox, ensuring you never have to stretch a worn-out tip past its useful life just to finish a shift. A fresh tip ensures smooth wire feeding; as tips wear, the hole becomes oval-shaped, causing the wire to wander and contact to become intermittent. This leads to micro-arcing inside the tip and frustrating stuttering at the workpiece. With the KP14H-35-B100, you get the tight tolerance and smooth bore needed for reliable feeding, even if the liner is getting a bit older or the cable is twisted.

Installing these tips is straightforward, fitting perfectly into the gas diffuser of your Magnum gun. The threads are machined to ensure a secure seat that maximizes electrical transfer and prevents gas leaks that could disturb your shielding coverage. Whether you are welding mild steel, stainless, or using flux-cored wires that match the diameter, these tips deliver the performance Lincoln Electric is known for. Stop fighting with wandering arcs and constant burnbacks—upgrade to the heavy-duty tips designed to handle the heat of professional welding.
