Lincoln Electric KP1939-1 Gasless Mig Nozzle 100A

Product Description

The LINCOLN ELECTRIC KP1939-1 is a gasless MIG welder nozzle designed for air-cooled flux-core welding applications. This nozzle replaces the standard gas-shielded contact tip assembly in setups where shielding gas is not used, allowing the welder to run self-shielded flux-core wire without obstruction. Rated at 100 amps, it is built for light-to-medium duty MIG welding tasks and is a direct-fit consumable component for compatible Lincoln Electric MIG welding guns. Welders, fabricators, and maintenance technicians typically install and replace this nozzle as a routine consumable during gun maintenance.

This nozzle is suited for flux-core, gasless MIG welding in residential, light commercial, and field repair scenarios where shielding gas cylinders are impractical or unavailable. The air-cooled design makes it appropriate for intermittent-duty cycles common in repair shops, farm equipment maintenance, and light structural fabrication. It is intended for use with Lincoln Electric MIG welding equipment as specified by the manufacturer.

Installation Notes

Nozzle replacement is performed by qualified welders or technicians following standard MIG gun maintenance procedures. Always power down and disconnect the welder from its power source before removing or installing any gun consumable. Use the appropriate spanner or nozzle removal tool to avoid damaging the gun body or diffuser threads. Follow the equipment manufacturer's guidelines for torque and seating to ensure proper electrical contact and arc stability.
