Lincoln Electric KP14-45 Mig Contact Tip .045 Copper Threaded

Product Description

The LINCOLN ELECTRIC KP14-45 is a copper MIG welding contact tip designed for use with older Lincoln Electric and Tweco-style MIG welding guns. The tip features a threaded connection and is sized for 0.045-inch (1.20 mm) minimum wire outside diameter, making it a direct-fit consumable for the corresponding gun bodies and liners. Copper construction provides reliable electrical conductivity and heat transfer at the point of arc initiation. Sold individually, this contact tip is a standard replacement consumable for professional welders and fabricators working in production or field environments.

This contact tip is suited for MIG welding applications in light industrial, fabrication shop, and field welding environments. It is compatible with gun assemblies built to the older Lincoln Electric or Tweco design standard, which are widely used across structural steel fabrication, general manufacturing, and maintenance welding. The threaded connection type allows for straightforward removal and installation during routine gun maintenance. Welders running solid wire or flux-core wire at 0.045 inches will find this tip sized appropriately for consistent wire feed and arc stability.

Compatibility

Designed for older Lincoln Electric-style and Tweco-style MIG welding guns using a threaded contact tip connection and 0.045-inch wire. Verify gun body and liner compatibility before installation.

Installation Notes

Contact tips are installed and serviced by welders and welding technicians as routine MIG gun maintenance. Power down and disconnect the welding gun from the wire feeder and power source before removing or installing the contact tip. Use the appropriate tip wrench or pliers to avoid damaging the tip or diffuser threads. Inspect the gas diffuser and nozzle for spatter buildup and replace as needed when servicing the contact tip.
