OVERVIEW

Legendary Performance for Heavy Fabrication

The Tweco Spray Master MS350 MIG Gun (1036-1615) is a powerhouse in the industrial welding world, specifically engineered to handle the rigors of high-amperage applications. Known affectionately by welders as the "Spray Master," this 350-amp air-cooled gun is designed to excel in spray transfer modes where heat generation is highest. With a 15-foot cable, it offers the necessary reach for working around large fixtures, structural steel, and heavy machinery without compromising on wire feedability.

This specific configuration comes ready to run 1/16" (1.6mm) wire, making it an excellent choice for heavy deposition welding on thick plate steel or aluminum. The gun features a standard Tweco backend connection, ensuring it plugs directly into a wide range of wire feeders and power sources that utilize the industry-standard Tweco adapter. The ergonomic handle is designed to fit naturally in the hand, reducing grip fatigue during long arc-on times, while the heavy-duty cable assembly resists cuts, burns, and abrasion in tough shop environments.

Maintenance is simplified thanks to Tweco's widely available consumables. The Spray Master series utilizes the robust 11-Series contact tips and heavy-duty diffusers, which are designed to conduct current efficiently and resist overheating. Whether you are fabricating yellow goods, structural beams, or performing heavy equipment repair, the MS350 delivers the consistency and durability Tweco is famous for.
