The ESAB Tweco WeldSkill 1420-1141 (WS42-4045-15) is a steel-wound replacement conduit liner for Gas Metal Arc Welding (GMAW) and Flux-Cored Arc Welding (FCAW) systems. It provides the internal channel for feeding solid or cored wires from the wire feeder through the torch cable to the contact tip.
Features
Zinc-plated spring wire construction to minimize corrosion on the metal surface
Machined brass alloy stop on the rear end for dimensional stability and thermal conduction
Roll-stamped part number on the brass stop for permanent identification
Field-trimmable length to match specific torch lead requirements
High columnar strength to prevent conduit collapse or wire bunching during cable bending
Helical coil design provides self-cleaning functionality by trapping metal flakes and lubricants
Smooth interior profile to reduce wire chattering and erratic micro-arcing
Corrosion-resistant finish isolates structural steel from environmental humidity and shop condensates
