The ESAB 0349303018 is a replacement steel liner designed for the PSF series of MIG welding torches. This component is critical for the guidance of welding wire from the wire feeder through the torch cable to the contact tip. It is manufactured to precise tolerances to ensure compatibility with ESAB PSF 250, PSF 305, PSF 405, and PSF 505 air-cooled and water-cooled guns.
This specific liner is engineered for use with hard wires, typically mild steel or low-alloy steel, with diameters ranging from 0.9mm (0.035 inches) to 1.2mm (0.045 inches). The liner measures 3 meters (approximately 10 feet) in length, matching the standard cable length of many PSF torch assemblies. Proper liner selection is essential for maintaining arc stability; a liner that is too large can cause erratic feeding, while one that is too small will increase friction and strain the drive motor.
Constructed from high-tensile steel wound in a spiral configuration, the liner provides the necessary flexibility to navigate the torch cable's bends while maintaining a rigid internal channel for the wire. Regular inspection and replacement of the liner are recommended as part of a preventative maintenance schedule to avoid issues such as micro-arcing inside the liner or accumulation of metal shavings and debris.
