The Miller 202890 is a steel monocoil liner assembly designed for Roughneck C-Series MIG guns. It is engineered for high-amperage industrial welding applications and accommodates wire diameters from .035" to .045". The liner is manufactured at a length of 16.5 feet to allow for precise trimming to fit 15-foot gun assemblies, ensuring a flush fit against the gas diffuser to prevent wire shaving accumulation.
Features
Zinc-plated steel construction to minimize surface corrosion
Round-wound design provides flexibility for gun cable navigation
Rigid monocoil structure prevents kinking or collapsing under drive roll pressure
Internal surface optimized to reduce friction and wire drag
Extended 16.5-foot length allows for custom trimming to ensure zero gaps at the diffuser
