The LINCOLN ELECTRIC KP2744-045-B100 is a threaded copper contact tip designed for MIG welding applications. It accepts 0.045-inch wire diameter and is rated to a maximum of 350 amps. The tip uses a Copper Plus design, which increases the diameter to allow for greater copper content per tip. The added copper mass disperses heat more effectively, helping the tip run cooler over longer duty cycles. Anti-seize threading on the tip body is engineered to prevent the tip from seizing or fusing to the diffuser during high-heat operation. This part is installed by welding professionals and maintenance technicians performing MIG wire-feed welding on light to heavy fabrication work.
This contact tip is designed for use with Lincoln Electric Magnum PRO MIG welding guns. It is a direct replacement part suited for shop, field, and production welding environments where 0.045-inch solid or flux-core wire is run. The threaded connection type allows for fast tip changes during continuous operation. It is sold as a single tip, making it easy to stock in multiples for high-volume welding operations where tip replacement is frequent.
Designed for use with Lincoln Electric Magnum PRO MIG welding guns running 0.045-inch wire diameter.
Contact tip replacement is performed by welding technicians and fabricators. Always power down the welding machine and allow the gun and diffuser to cool before removing or installing a contact tip. Use the appropriate tip wrench or pliers to avoid cross-threading when installing. Inspect the diffuser and nozzle for spatter buildup at each tip change to maintain proper gas coverage and wire feeding.
