OVERVIEW

Tweco SMV415M116 Spray Master V-Series MIG Gun - 400A, 15ft, Miller

Upgrade your welding setup with the Tweco Spray Master SMV415M116, a 400-amp air-cooled MIG gun that combines the legendary toughness of the Spray Master line with the advanced performance of Velocity consumables. This model is specifically configured with a Miller-style back-end plug and a 15-foot cable, offering seamless compatibility with most Miller wire feeders. It is factory-ready to feed 1/16-inch (1.6mm) wire, making it a powerhouse choice for heavy fabrication shops utilizing larger diameter wires for high deposition rates.

The standout feature of this gun is the Velocity consumable system. Traditional MIG front ends can be complex and prone to overheating. The Velocity system eliminates the need for a gas diffuser entirely. Instead, the contact tip integrates the gas distribution ports and seats directly into the conductor tube. This "solid copper" path maximizes electrical efficiency and pulls heat away from the arc zone much more effectively than threaded designs. The result is a cooler running gun, longer-lasting tips, and a smoother, more consistent arc. The nozzle is also designed to stay cooler and resist spatter adhesion, reducing the frequency of cleaning.

Built for the professional welder, the Spray Master V-Series features a rugged, impact-resistant handle and a heavy-duty cable that withstands the abuse of industrial environments. The 15-foot length provides ample workspace coverage, while the metal-jacketed conductor tube ensures rigidity and durability. Maintenance is simplified thanks to the reduced part count in the front end—fewer threads to cross and fewer parts to lose. If you need a reliable, high-amperage MIG gun that reduces downtime and improves weld quality, the Tweco SMV415M116 is the industry standard.

FAQ

This gun uses Tweco Velocity series consumables, which feature a simplified design with fewer parts and better cooling.

Yes, it comes pre-installed with a liner suitable for 1/16 inch (1.6mm) wire.

It is compatible with Miller wire feeders and welders that accept a standard Miller-style MIG gun connection.

Yes, but you will need to change the liner and contact tip to match the smaller wire diameter (e.g., 0.035" or 0.045").

The gun is rated at 400 Amps at 80% duty cycle with CO2 gas.

No, the Velocity consumable system eliminates the separate gas diffuser; the contact tip handles gas distribution.

The Velocity nozzle is a slip-on type that is adjustable and held in place by the internal geometry of the contact tip and conductor tube.

The Tweco Spray Master SMV415M116 is an air-cooled MIG gun.
