Industrial RAD64007021 Liner Assembly

Description:

The RAD64007021 Liner Assembly is used in industrial welding systems to guide and protect welding wire as it travels through a MIG gun cable assembly. It is commonly installed in heavy-duty MIG welding equipment used in fabrication shops, structural steel production, shipbuilding, and industrial manufacturing where consistent wire feed performance is required over long cable lengths. Maintenance technicians, welders, and OEM service teams use this liner for replacement of worn or contaminated liners, restoration of stable wire feeding, and maintenance of welding gun performance in production environments.

Applications:

The RAD64007021 liner assembly is commonly used in industrial welding operations including structural steel fabrication, heavy equipment repair, shipbuilding, railcar manufacturing, and general metal fabrication where 3/32"–7/64" wire sizes are used in 15-foot MIG gun assemblies requiring smooth, low-friction wire delivery for stable arc performance and reduced feed disruptions.
