OVERVIEW

Tweco Spray Master MS415 – 400A Miller Style

Experience the legendary performance of the Tweco Spray Master series with the MS415 MIG gun. Built for the professional welder who demands reliability, this 400-amp air-cooled gun is a workhorse in the industry. The MS415 is designed to withstand the rigors of high-duty cycle welding while providing superior operator comfort. The ergonomic handle fits naturally in the hand, reducing fatigue during extended welding sessions, while the trigger action is smooth and responsive.

This model features a direct Miller-style backend connection, making it a plug-and-play replacement or upgrade for your existing Miller equipment. The 15-foot lead gives you the necessary standoff distance for large assemblies, and the cable's rugged construction prevents kinking and crushing. It is specifically configured for running 1/16" (1.6mm) wire, making it an excellent choice for flux-cored or solid wire applications on heavy-gauge steel.

One of the standout features of the Spray Master line is its serviceability. The simplified design allows for quick liner changes and easy access to the trigger mechanism. The gun uses industry-standard Tweco consumables, ensuring that replacement tips, nozzles, and diffusers are always easy to find. If you are looking for a MIG gun that combines heavy-duty power with air-cooled simplicity, the Tweco Spray Master MS415 is the tool for the job.
