Genuine ESAB Reliability for ST-16 and ST-21 Guns

Keep your welding operations running smoothly with the ESAB Centering Bushing (17782), a genuine replacement part tailored for the ST-16 and ST-21 series of MIG guns. In the world of professional welding, the quality of your consumables and replacement parts directly impacts the quality of your work. This centering bushing is manufactured to ESAB’s exacting standards, ensuring a perfect fit and restoring your equipment to factory-level performance. It is an essential component for welders working in sectors such as transportation, railcar manufacturing, and general heavy fabrication.

The 17782 bushing is designed for power and versatility. With a 600 Amp rating, it is capable of handling high-current applications without overheating, supported by its integration into water-cooled systems. This makes it ideal for continuous welding operations where equipment reliability is non-negotiable. The bushing supports a wide variety of wire types, including solid steel, aluminum, and flux-cored wires up to 3/32 inch (and maxing out at 7/64 inch). This flexibility allows shops to switch between different welding tasks without worrying about component limitations.

Key Benefits for the Welder:

• Consistent Feeding: The precision-machined bore ensures that wire travels smoothly from the feeder to the liner, minimizing bird-nesting and erratic arc issues.
• Euro-Style Compatibility: Designed to fit standard Euro-style feeders, making it a versatile choice for shops with mixed equipment fleets.
• Durability: Built with high-quality materials to resist wear and thermal stress, reducing the frequency of part replacements.

Beyond its core function, the bushing contributes to the overall ergonomics of the welding gun. It features a strain relief spring that helps manage the weight and movement of the cable assembly, reducing stress on the connection point. This design consideration not only protects the equipment but also contributes to a more stable and comfortable welding experience. When your ST-16 or ST-21 gun needs maintenance, trust the ESAB 17782 Centering Bushing to deliver the performance and longevity your shop requires.
