The ESAB ST-16/21 Centering Bushing (17782) is a critical replacement component designed to maintain the integrity and performance of your water-cooled MIG welding systems. Engineered specifically for the renowned ST-16 and ST-21 MIG guns, this bushing serves as the central interface between the gun and the wire feeder, ensuring precise alignment and electrical conductivity. In high-stakes industrial environments where downtime equates to lost revenue, relying on genuine ESAB parts guarantees that your equipment operates at peak efficiency.
Rated for a substantial 600 Amps, this centering bushing is built to withstand the rigorous demands of heavy fabrication, shipyards, and offshore construction. It is fully compatible with any shielding gas, providing flexibility across various welding procedures. The component features a robust design that supports water-cooling mechanisms, essential for managing the heat generated during high-amperage welding cycles. By effectively managing thermal loads, it prolongs the lifespan of the torch and ensures consistent weld quality over long shifts.
One of the standout technical features of the 17782 bushing is its versatility in wire handling. It is engineered to accommodate a broad spectrum of wire diameters, ranging from fine .030 inch wires up to heavy-duty 7/64 inch wires. This range covers the vast majority of industrial applications, from precision aluminum work to heavy flux-cored structural welding. The internal geometry is optimized to reduce friction, promoting smooth and consistent wire feeding which is crucial for maintaining a stable arc and reducing spatter.
Installation is straightforward thanks to its compatibility with Euro-Style feeders. The assembly includes a strain relief spring and an improved connector design, which provides enhanced comfort and support at the back end of the gun. This attention to ergonomic and mechanical detail helps prevent cable strain and connection fatigue, common failure points in manual welding operations. Whether you are welding railcars or general industrial structures, the ESAB ST-16/21 Centering Bushing delivers the reliability professional welders demand.
