Lincoln Electric KP2773-2-B25 Insulating Bushing 25pk

Product Description

The LINCOLN ELECTRIC KP2773-2-B25 is a copper insulating bushing designed for MIG welding gun maintenance and repair. This bushing serves as an electrical insulator within the gun assembly, isolating conductive components and protecting the gun body from arc damage and current leakage. Built from copper, it provides reliable conductivity and durability in high-heat welding environments. The KP2773-2-B25 is sold as a single unit with a minimum order quantity of 25, making it well suited for shop stock and fleet maintenance programs. Welding technicians and maintenance personnel handling MIG gun consumable replacement are the primary installers.

This insulating bushing is intended for use with 350A Magnum PRO expendables. It fits into the front-end assembly of compatible Magnum PRO MIG guns, where it provides isolation between the nozzle, contact tip holder, and gun body. It is a standard replacement consumable typically stocked in production welding shops, fabrication facilities, and field service kits where Magnum PRO torches are in regular use. Ordering in the 25-unit quantity supports continuous operation with minimal downtime during consumable changeouts.

Installation Notes

Installation should be performed by a qualified welding technician or maintenance professional. Always power down and disconnect the MIG welder from its power source before servicing the gun assembly or replacing front-end consumables. Handle copper components carefully to avoid deformation, which can affect the insulating fit and lead to premature failure or arc damage to the gun body.
