0559211013 - ESAB GlobalPro Steel Liner 0.035-0.045 13ft

Technical Overview of the ESAB GlobalPro Steel Liner

The ESAB 0559211013 is a specialized steel liner designed for use with the GlobalPro series of MIG welding guns. This component is critical for the mechanical transport of welding wire from the wire feeder to the contact tip. It is engineered to accommodate hard wires, specifically mild steel and low-alloy wires, with diameters ranging from 0.035 inches (0.9 mm) to 0.045 inches (1.2 mm). The liner measures 13 feet in length, making it suitable for standard 13-foot or 4-meter gun cable assemblies.

Constructed from high-quality wound steel, this liner provides the necessary structural integrity to prevent collapsing or kinking while the gun cable is bent during operation. The internal surface finish is optimized to minimize friction coefficients, ensuring that the drive rolls can push the wire smoothly without slippage or excessive motor load. Proper liner selection is essential for maintaining arc stability; a worn or clogged liner can increase electrical resistance and mechanical drag, leading to burn-back or erratic feeding. This OEM part ensures dimensional accuracy for a secure fit within the GlobalPro power pin and gun neck.

Installation involves removing the old liner, inserting the new unit, and trimming any excess length according to the specific gun model's stick-out requirements. Regular inspection and replacement of the liner are recommended as part of a preventative maintenance schedule to ensure optimal welding parameters and equipment longevity.
