The Tweco Spray Master MS315 MIG Gun (1036-1715) is a premier choice for industrial welding applications requiring reliability, comfort, and high performance. Rated at 350 Amps at 80% duty cycle, this air-cooled MIG gun is engineered to withstand the rigors of heavy fabrication environments. This specific configuration is tailored for operators using Lincoln Electric wire feeders, featuring a direct K4-style rear connection that ensures a secure and efficient current transfer.
Designed with a 15-foot cable, the MS315 provides ample reach for working around large assemblies without compromising wire feedability. The gun comes pre-setup for 1/16-inch (1.6mm) welding wire, making it an immediate solution for heavy structural steel, shipbuilding, and heavy equipment manufacturing where larger diameter wires are standard. The Spray Master series is famous for its maintainability; the simplified design allows for quick repairs and consumable changes, minimizing downtime on the shop floor.
The ergonomic handle is shaped to fit the natural curve of the welder's hand, significantly reducing fatigue during extended arc-on times. Additionally, the conductor tube can be rotated 360 degrees, allowing welders to access difficult joints without straining their wrists or the cable. Utilizing standard Tweco consumables—including 11 Series contact tips and 24 Series nozzles—this gun ensures that replacement parts are easy to find and cost-effective. Whether you are welding mild steel, stainless, or aluminum (with the appropriate liner change), the Tweco Spray Master delivers consistent arc stability and superior wire feeding performance.
