Replace a damaged or inaccurate guide inside your welding gun with this Lincoln MIG welder liner. The liner is one of the most important welding parts, directing your wire from the feeder to the contact time. The Lincoln KP1934-1 liner fits any MIG gun that uses 42-4045-15 wire between 0.035" and 0.045" thick. If you're not sure whether your MIG welding gun is a match, head to the Lincoln support page or call to speak with a WeldingMart expert.
