Lincoln Electric KP34A Mig Welder Insulating Bushing

Product Description

The LINCOLN ELECTRIC KP34A is a slip-on, air-cooled insulating bushing designed for MIG welding guns. It serves as an insulator between the contact tip holder and the nozzle, preventing arc flash and protecting the gun body from heat and electrical contact. Rated for use at 300 and 400 amps, this bushing is built for demanding production and fabrication environments. Installation is straightforward and requires no tools. Licensed welding technicians and shop fabricators handling Lincoln MIG gun maintenance and consumable replacement are the primary users of this part.

This insulating bushing fits Lincoln MIG welding guns rated at 300 and 400 amps. It is suited for both shop and field maintenance scenarios where gun components require replacement during routine consumable service. The slip-on design allows for fast removal and reinstallation without disassembling the full gun assembly, making it practical for high-cycle production settings as well as general fabrication work.

Installation Notes

Installation is performed by welding technicians during routine MIG gun consumable service. Disconnect the welder from its power source and allow the gun to cool completely before handling any consumable components. Slip the bushing onto the contact tip holder before threading on the nozzle. Follow the gun manufacturer's assembly sequence to ensure proper seating and electrical isolation.
