The Tweco Spray Master MS350 MIG Gun (1036-1725) is a premier choice for industrial fabricators requiring a robust, air-cooled solution for high-amperage welding. Engineered specifically for the demands of spray transfer welding, this model is rated at 350 Amps at an 80% duty cycle when using Argon mixed gases, significantly outperforming standard MIG guns in thermal management and longevity. This specific configuration comes equipped with a 15-foot (4.5 meter) cable, providing ample reach for working around large assemblies without compromising wire feedability.
Out of the box, this Spray Master gun is set up to run 1/16-inch (1.6mm) welding wire, making it an immediate solution for heavy structural steel fabrication, heavy equipment manufacturing, and vessel welding where higher deposition rates are required. The internal liner and contact tip geometry are selected to ensure smooth wire feeding and consistent electrical contact, which is critical for maintaining a stable arc in spray transfer modes.
This unit features a standard Tweco-style rear connection, ensuring seamless compatibility with a vast range of wire feeders and power sources that utilize the industry-standard Tweco adapter. Maintenance is simplified through the use of standard Tweco consumables, including the widely available 11 Series contact tips, 52/54 series gas diffusers, and adjustable slip-on nozzles. The simplified front-end design allows for quick consumable changes, reducing downtime on the shop floor.
The Spray Master series is renowned for its ergonomic handle, which is designed to fit naturally in the welder's hand, reducing grip fatigue during long welding shifts. The conductor tube can be rotated 360 degrees, allowing the operator to adjust the torch angle for optimal access to joints in difficult positions. The cable itself is constructed with heavy-duty copper stranding and a durable outer jacket that resists cuts, abrasion, and heat, ensuring the gun withstands the harsh environment of industrial manufacturing.
