375781-002 - Tweco MIG Gun Receptacle for Wire Feed Heads

Reliable Connection for Industrial Wire Feeders

The Tweco 375781-002 Gun Receptacle is a critical component designed to maintain the integrity of your MIG welding system. Located at the feed head of the wire feeder, this receptacle serves as the primary interface between the power source's wire drive mechanism and the welding gun. In industrial environments where equipment is subjected to continuous high-amperage use, the quality of this connection is paramount. This genuine Tweco replacement part is engineered to precise tolerances, ensuring a secure mechanical fit that prevents movement, vibration, and the subsequent arcing that can damage both the gun and the feeder.

Constructed from high-grade brass and copper alloys, the receptacle offers superior electrical conductivity. This low-resistance path is essential for maintaining a stable arc and preventing voltage drops that can lead to inconsistent weld quality. Furthermore, the unit is designed to facilitate the seamless transfer of shielding gas from the machine solenoid to the gun liner, featuring precision-drilled ports and sealing surfaces that minimize the risk of gas leaks and porosity in the weld metal.

Maintenance professionals understand that the gun receptacle is a wear item. Over time, the repeated insertion and removal of the MIG gun, combined with thermal cycling, can loosen the internal contact surfaces. Replacing a worn receptacle with the 375781-002 restores the machine to factory specifications. It is compatible with specific wire feed heads designed for Tweco-style connections, making it an indispensable spare part for maintenance, repair, and operations (MRO) inventories. Installation is straightforward, allowing technicians to minimize equipment downtime and maintain high productivity levels on the shop floor.

By choosing genuine Tweco components, you ensure compatibility and longevity. Generic alternatives often lack the material density and machining precision required for heavy-duty applications. This receptacle assembly provides the durability needed to withstand the rigors of daily fabrication work, ensuring that your wire feeding system operates smoothly and efficiently shift after shift.
