328P23473A - ESAB Anthracite MIG Liner 3m for 1.2-1.6mm Wire

Technical Overview: ESAB 328P23473A Anthracite Liner

The ESAB 328P23473A is a specialized MIG gun liner designed to optimize wire feeding performance in industrial welding environments. Designated as an "Anthracite" liner, this component is typically constructed from a Polyamide/Carbon (PA/Carbon) blend. This material composition offers a critical advantage over standard steel spiral liners: significantly reduced coefficient of friction. This characteristic is essential when feeding softer wires such as aluminum or wires prone to surface damage like stainless steel, although it performs exceptionally well with standard steel wires where long-distance feeding is required.

This specific liner is engineered for wire diameters ranging from 1.2mm to 1.6mm (approximately 0.045 inches to 1/16 inches). The internal diameter is calibrated to support the wire column sufficiently to prevent buckling while allowing enough clearance for smooth travel. With a total length of 3 meters (approx. 10 feet), it is suitable for standard length ESAB MIG torches. Proper liner maintenance is crucial for arc stability; a worn or clogged liner is a leading cause of erratic wire feeding, burn-back, and unstable arcs. The PA/Carbon material also provides better heat resistance than pure Teflon (PTFE) liners, making it a durable choice for high-amperage applications.

Installation of the 328P23473A follows standard ESAB torch maintenance procedures. Technicians should ensure the liner is trimmed to the correct length and that no burrs obstruct the inlet or outlet, ensuring seamless integration with the wire feeder and contact tip.
