10361638 - Tweco Spray Master 350 MIG Gun, 12ft, Miller Connection, 1/16 Wire Setup

Heavy-Duty Tweco Spray Master MIG Gun for Industrial Welding

The Tweco Spray Master MS312M116 is a premium air-cooled MIG gun designed to meet the rigorous demands of high-amperage welding environments. Rated at 350 Amps with an 80% duty cycle using CO2 gas, this gun is engineered for durability and performance. It comes pre-configured with a Miller-style backend connection, making it an immediate plug-and-play solution for welders using Miller wire feeders and power sources. The 12-foot cable length offers a practical balance, providing sufficient reach for most workbench and jig applications while ensuring smooth and consistent wire feeding, particularly for the thicker 1/16-inch wire this unit is set up to run.

One of the standout features of the Spray Master series is its ergonomic design. The handle is contoured to fit comfortably in the welder's hand, reducing fatigue during extended periods of use. Maintenance is straightforward thanks to the use of standard Tweco consumables, including the widely available 11 Series contact tips and 52/54 series gas diffusers. The conductor tube is robust and capable of rotating 360 degrees, allowing operators to adjust the gun angle for better access to difficult joints without straining their wrists. Whether you are working in heavy equipment manufacturing, structural steel fabrication, or general industrial repair, the Tweco Spray Master delivers the reliability and arc stability professionals trust.
