0700200098 - ESAB MXL Series Liner Retaining Nut

Secure Your Wire Feed with the ESAB Liner Lock Nut

In the world of industrial MIG welding, consistency is key. The smallest component can often dictate the quality of the weld, and the ESAB Liner Lock Nut (0700200098) is a prime example of a small part playing a massive role. Designed specifically for the popular ESAB MXL series of MIG torches—including the MXL 200, MXL 270, and MXL 340—this lock nut is the essential fastener that secures your wire liner within the gun assembly. Without a properly secured liner, welders can experience erratic wire feeding, bird-nesting, and inconsistent arc stability, all of which lead to downtime and rework.

At Josef Gas, we understand that maintaining your equipment with genuine OEM parts is the best way to ensure longevity and performance. This liner lock nut is manufactured to ESAB's exact specifications, ensuring it threads perfectly onto your existing torch body without stripping or cross-threading. It provides the necessary tension to hold the liner against the gas diffuser or power pin, depending on the specific torch configuration, ensuring that the wire travels smoothly from the feeder to the contact tip.

Routine maintenance of your MIG gun often involves changing the liner, especially when switching between steel and aluminum wires or after extended use. During these changeovers, the lock nut can easily be misplaced or damaged. Keeping a spare ESAB 0700200098 in your maintenance kit ensures that your production line doesn't stop for a missing nut. Whether you are running a fabrication shop or a heavy industrial manufacturing floor, relying on genuine ESAB components guarantees that your MXL torches perform at their rated capacity.

Key Benefits for Industrial Users:

• Precision Fit: Guaranteed compatibility with MXL 200, 270, and 340 models eliminates guesswork.


• Operational Continuity: Prevents liner slip which causes wire feed stuttering.


• Durability: Made from high-quality materials to resist heat and mechanical stress.
