The Lincoln Electric KP2632-1 Magnum 100SG Barrel Liner is a replacement barrel liner designed for the Magnum® 100SG Spool Gun. A properly fitted liner helps maintain consistent wire feeding by guiding the electrode wire through the gun barrel, reducing drag and minimizing feed interruptions that can contribute to burnbacks and erratic arc starts. This is the correct OEM-style liner for routine maintenance or liner replacement when feeding performance begins to degrade.
