The Miller 210970 is a specialized monocoil conduit liner designed to facilitate the smooth transfer of welding wire from the feeder to the contact tip. Engineered for precision and durability, this liner is compatible with wire diameters ranging from .023 inches to .035 inches, covering the most common sizes used in light industrial and hobbyist MIG welding applications. It is manufactured to meet the strict tolerances required by Miller Electric, ensuring consistent performance and longevity.
This specific liner is the designated replacement part for the Auto Arc 130 Series MIG guns and is also fully compatible with the Hobart H-9A MIG gun. With a total length of 8 feet, it is sized perfectly for these compact gun assemblies, eliminating the need for excessive trimming in standard setups. The monocoil construction provides the necessary flexibility to navigate the gun cable while maintaining a rigid internal structure that prevents the wire from buckling or dragging.
Regular maintenance of the MIG gun liner is critical for weld quality. Over time, liners can accumulate copper dust, dirt, and debris, or become kinked, leading to erratic wire feeding known as "chatter." Replacing a worn liner with the genuine Miller 210970 restores the mechanical integrity of the wire feed system, ensuring a stable arc and reducing downtime associated with wire jams.
Installation of the 210970 liner is straightforward for maintenance personnel and operators. It is designed to seat correctly in the power pin of the specified Auto Arc and Hobart models. Users should verify their gun model before purchase, as this 8-foot liner is shorter than standard 15-foot industrial liners and is specific to the equipment listed.
