Don't let a worn-out contact tip ruin your weld bead. The Tweco 14-40 (1140-1103) is the industry-standard replacement tip for welders running 0.040-inch wire. Whether you are using a classic Tweco Spray Master, a Mini-MIG, or a Magnum gun, these tips deliver the smooth wire feeding and stable arc transfer you need to lay down quality welds.
The contact tip is the final transfer point for welding current, making it one of the most critical components in your MIG gun. These genuine Tweco 14 Series tips are precision-drilled to minimize friction while ensuring positive electrical contact. This reduces the chance of the wire "floating" inside the tip, which can cause arc wandering. The copper construction effectively dissipates heat, prolonging the life of the tip even during long beads.
This pack of 25 ensures you always have a fresh tip on hand when spatter builds up or the bore becomes oval-shaped. Changing your tip regularly is the easiest way to troubleshoot wire feed issues. The 14-40 fits a huge range of guns, including the Tweco #1 through #4 series, making it a versatile addition to any welder's toolbox. Simply screw it into your gas diffuser (1/4"-28 thread) and you are ready to weld.
