Lincoln Electric 3/64" Notched Contact Tip (10-Pack) for Magnum Guns

Maximize Arc Stability with Lincoln Electric Notched Contact Tips

Achieve superior welding performance with the Lincoln Electric KP2010-5B1 Contact Tip, a premium consumable designed for the rigorous demands of professional MIG welding. This contact tip is precision-engineered to handle 3/64-inch (1.2 mm) welding wire, providing a smooth and consistent path for wire delivery. Poor contact tip quality is a leading cause of arc instability, burn-backs, and erratic feeding; by choosing genuine Lincoln Electric parts, you ensure that your Magnum® series MIG gun operates at peak efficiency.

The KP2010-5B1 features a distinct notched base. This configuration is specifically designed to interface seamlessly with the gas diffusers found in Magnum® 200, 300, 400, and 250L welding guns. The notch locks the tip in position, preventing rotation that can occur due to wire friction or movement of the gun cable. This mechanical stability is crucial for maintaining consistent electrical contact point (stick-out) and gas coverage, resulting in cleaner welds with less spatter.

Durability is paramount in high-amperage welding environments. These contact tips are machined from a robust copper alloy that offers excellent thermal conductivity and hardness. This material choice helps dissipate heat rapidly, preventing the tip from softening or fusing to the wire during long welds. The internal bore is finished to tight tolerances to reduce friction, allowing the wire to feed smoothly even when the gun cable is bent or manipulated in tight spaces.

Performance Benefits

• Consistent Electrical Transfer: Ensures a hot, stable arc for better penetration.
• Reduced Downtime: Long-lasting copper alloy reduces the frequency of tip changes.
• Quick Replacement: Notched drop-in style allows for fast changeovers without threading tools.
• Versatility: Perfect for 3/64" aluminum or steel wires used in various fabrication sectors.

Sold in packs of 10, the Lincoln KP2010-5B1 is an essential stock item for any welder using compatible Magnum equipment. Don't let worn consumables compromise your weld quality—upgrade to Lincoln Electric's trusted contact tips for reliable, professional results every time you pull the trigger.
