The PRO-SOURCE 45V27 is a TIG torch collet body designed to hold and align the collet and tungsten electrode within a TIG welding torch assembly. This component serves as the primary current-conducting interface between the torch head and the collet, ensuring consistent electrical contact and proper tungsten positioning during the weld. Measuring 2.12 inches in height and 0.62 inches in width, the 45V27 is a compact, direct-replacement part suited for professional welders and service technicians performing torch maintenance or rebuilds.
This collet body is used in TIG welding applications across fabrication shops, maintenance facilities, and field service environments. It is appropriate for both light industrial and professional trade use wherever a compatible TIG torch requires collet body replacement due to wear, damage, or contamination. Welders and torch service technicians are the primary installers of this component during routine torch servicing.
Designed as an OEM-style replacement collet body for compatible TIG torch assemblies. Verify torch model and collet series before ordering to confirm fitment.
Installation should be performed by a qualified welder or torch technician. Always disconnect the welding machine from its power source and allow the torch to cool completely before disassembling the torch head or replacing internal components. Handle the collet body carefully to avoid contaminating the bore, as debris or oils can affect electrical contact and tungsten alignment. Confirm that the replacement collet body matches the torch series and tungsten diameter in use before final assembly.
