Xtrweld KP1939-1 Gasless Mig Nozzle 2 Pack

Product Description

The XTRWELD KP1939-1 is a gasless MIG nozzle designed to protect the end of a MIG gun from spatter buildup during flux core wire welding. This nozzle fits Tweco-style MIG guns and provides a physical barrier at the gun tip, reducing the accumulation of spatter that can interfere with wire feed and arc performance. Sold in a pack of 2, it is a direct consumable replacement for welding professionals and fabricators who run self-shielded flux core wire on a regular basis. Installation requires no tools and is part of routine gun maintenance.

This nozzle is intended for use in gasless flux core welding applications where no external shielding gas is used. It is commonly installed on Tweco-compatible MIG guns in light industrial, structural, and general fabrication settings. The KP1939-1 is also referenced as a compatible replacement for use on Lincoln Magnum 100L MIG guns. Welders performing high-deposition flux core passes benefit from replacing this nozzle regularly to maintain clean wire delivery and consistent arc starts.
