The Tweco 18250 Handle Bushing is a critical replacement part designed to restore the functionality and safety of Tweco No. 4 (400 Amp) MIG guns. In the world of heavy fabrication, the MIG gun handle is the welder's primary interface with the machine. A loose or damaged handle not only affects bead precision but can also pose safety risks if the cable assembly is not properly retained. This bushing serves as the anchor point, locking the cable assembly securely into the handle shell and preventing axial movement or rotation that could strain internal crimps and connections.
Constructed from high-impact, insulating material, the 18250 bushing is built to survive the harsh conditions of a welding shop. It fits snugly around the cable crimp area and nests within the molded ribs of the handle case. When the handle screws are tightened, the bushing compresses slightly to create a rigid, non-slip bond. This is particularly important for welders who manipulate the gun into difficult positions, as it ensures the torch head remains aligned with the welder's hand movements. Using genuine Tweco parts like the 18250 ensures that the airflow and cooling characteristics of the gun are maintained, as improper spacing from ill-fitting parts can restrict air movement inside the handle.
Installation is straightforward and requires only a screwdriver to open the handle case. Replacing a worn or cracked bushing is a quick fix that significantly improves the feel of the gun. If you notice your Tweco No. 4 handle feeling "sloppy" or if the cable seems to be pulling out of the rear of the gun, the 18250 bushing is likely the part you need. Don't compromise on the performance of your classic Tweco gear; trust genuine ESAB/Tweco replacements to keep your arc smooth and your equipment reliable.
