003-2147 - MK Python Air-Cooled Gooseneck Barrel 60 Degree

Technical Overview of the MK Products 003-2147

The MK Products 003-2147 is a replacement gooseneck barrel assembly designed exclusively for the MK Python series of push-pull MIG welding guns. This component is engineered to meet the precise dimensional tolerances required by the Python's wire feed path, ensuring seamless wire delivery from the rear drive motor to the contact tip. The barrel features a 60-degree bend radius, which is a standard configuration for general fabrication, offering a balance between reach and ergonomic comfort.

Constructed for air-cooled operation, this barrel utilizes high-grade conductive alloys to manage thermal loads generated during welding while maintaining structural rigidity. It connects directly to the Python gun body, integrating with the internal gas and power delivery systems. The internal bore is finished to minimize friction against the liner, which is critical when feeding softer filler metals like aluminum series 4043 or 5356. Proper maintenance of the gooseneck, including regular inspection for thread wear or impact damage, is essential for maintaining the high-performance standards of the MK Python system.

This part is identified by the manufacturer SKU 003-2147 and is supplied as a single unit. It does not include the contact tip, gas diffuser, or nozzle, which must be selected separately based on the specific welding application and wire diameter. Technicians should verify the cooling method of their existing torch setup, as this specific SKU is rated for air-cooled (A/C) configurations only and is not compatible with water-cooled Python models.
