KP1937-3 - Lincoln Electric Magnum 100L MIG Gun Liner .023-.035

Genuine Lincoln Electric KP1937-3 Liner Assembly

The Lincoln Electric KP1937-3 Liner Assembly is a critical replacement component designed to maintain the operational efficiency of your MIG welding equipment. Specifically engineered for the SP-135T and compatible with the widely used Magnum 100L MIG gun series, this liner ensures the smooth delivery of welding wire from the drive rolls to the contact tip. Maintaining the integrity of your wire delivery system is essential for industrial applications where consistency and uptime are paramount. This liner is calibrated for wire diameters ranging from 0.023 inches to 0.035 inches, covering the most common sizes used in light-to-medium fabrication and maintenance tasks.

Over time, MIG liners can become clogged with metal shavings, lubricant debris, and shop dust, or they may develop kinks that increase friction. This friction results in erratic wire feeding, often diagnosed as a surging arc or 'burn-back.' By replacing your worn liner with a genuine Lincoln Electric KP1937-3, you restore the low-friction path required for stable arc performance. The liner features a durable steel spiral wound construction that provides the necessary flexibility for maneuvering the gun while maintaining a rigid internal channel for the wire. It is designed to be trimmed to length during installation, ensuring a perfect fit for 10-foot cable assemblies commonly found on compact Lincoln power sources.

Josef Gas provides only authentic Lincoln Electric consumables to ensure that your equipment meets original manufacturer specifications. Using OEM parts like the KP1937-3 guarantees correct gas flow characteristics and electrical insulation, preventing potential grounding issues inside the cable. Whether you are running solid steel wire with shielding gas or flux-cored wire, this liner offers the durability and precision required for professional results.
