10361726 - Tweco Spray Master MS350 MIG Gun, 350A, 15ft, Miller Plug, 1/16 Wire

Heavy-Duty Industrial MIG Gun for High-Amperage Applications

The Tweco Spray Master MS350 MIG Gun (SKU: 1036-1726) is a premier air-cooled welding torch designed to meet the rigorous demands of heavy industrial fabrication. Engineered for durability and performance, this model is rated at 350 Amps at an 80% duty cycle using CO2 gas, making it an exceptional choice for flux-cored and spray transfer MIG welding processes. This specific configuration features a 15-foot (4.6 meter) cable and a direct Miller-style backend connection, allowing for seamless integration with compatible Miller wire feeders and power sources without the need for adapters.

Out of the box, the MS350 is set up for 1/16-inch (1.6mm) welding wire, a common size for structural steel, heavy equipment manufacturing, and shipbuilding. The gun utilizes Tweco's robust cable design, which ensures consistent wire feeding and excellent electrical conductivity. The "EL" designation in the part number indicates the inclusion of Eliminator style front-end consumables. These consumables are designed to streamline maintenance by combining the gas diffuser and contact tip holder into a more efficient system, often providing better gas coverage and longer consumable life compared to standard setups.

Maintenance and serviceability are core strengths of the Spray Master series. The gun features a split-handle case that allows for easy access to the trigger and internal connections, minimizing downtime during repairs. The conductor tube is encased in a heavy-duty metal jacket and can be rotated 360 degrees, providing welders with the flexibility needed to access difficult joints. With its high duty cycle, robust construction, and ergonomic design, the Tweco Spray Master MS350 is the reliable workhorse required for continuous, high-deposition welding environments.
