OVERVIEW

Industry Standard for Aluminum MIG Welding

The MK Products Python® series represents the pinnacle of push-pull welding gun technology. Designed specifically to address the challenges of feeding soft wires such as aluminum, the Python gun utilizes a robust mechanical design that has been field-proven in the most demanding industrial environments. This specific model, the 291-815, is a 15-foot, air-cooled configuration equipped with a back-end connection compatible with Miller® wire feeders and power sources.

At the core of the Python's performance is MK Products' legendary drive system. By synchronizing a pull motor in the gun handle with the push motor in the feeder, the system maintains constant tension on the wire, effectively eliminating friction-related feeding issues and the dreaded "bird-nesting" common with standard push-only guns. This ensures stable arc starts and consistent weld bead geometry, which is critical for code-quality aluminum fabrication.

Key Technical Specifications

The air-cooled Python is rated for 200 Amps at 100% duty cycle, making it a workhorse for continuous production environments where water cooling is not feasible or desired. The gun features the patented EZ-Lock® barrel system, allowing the operator to rotate the barrel 360 degrees for optimal access to joints or replace the barrel instantly without tools. The ergonomic handle is designed to balance weight distribution, reducing wrist strain during long shifts.

This unit comes ready to connect to compatible Miller equipment, streamlining integration into existing welding cells. It supports a wide range of wire diameters, typically from 0.030" to 1/16" for aluminum, and is also suitable for stainless steel and flux-core applications where long reach and feeding reliability are paramount.

FAQ

The air-cooled Python gun is rated at 200 Amps at 100% duty cycle using Argon gas.

It fits Miller machines with a standard Miller back-end connection, but the machine must support push-pull gun operation (often requiring a specific control module or 14-pin connection depending on the feeder).

Yes, while designed for aluminum, the Python push-pull system works excellently for steel and stainless steel, especially over longer distances.

Yes, the Python features the EZ-Lock® barrel system which allows the barrel to rotate 360 degrees or be removed quickly.

The Python generally supports wire diameters from 0.030" (0.8mm) up to 1/16" (1.6mm) for aluminum, depending on the drive rolls and liner installed.

No, this is the air-cooled (gas-cooled) version. A water-cooled version is available separately if higher amperage is required.

This specific model (291-815) comes with a 15-foot cable assembly.

Yes, it typically ships with a standard set of drive rolls, but you should verify the specific groove size matches your wire diameter before use.
