10361610 - Tweco Spray Master MS350 MIG Gun - 350A, 10ft, 1/16 Wire, Tweco Connection

Heavy-Duty Industrial MIG Welding Gun

The Tweco Spray Master MS350 MIG Gun (SKU: 1036-1610) is a premier solution for industrial fabrication environments requiring robust performance and reliability. Part of the renowned Spray Master series, this air-cooled gun is engineered to handle high-amperage applications without the complexity of water-cooling systems. It is rated for 350 Amps at an 80% duty cycle using CO2 gas, making it an exceptional choice for continuous manufacturing processes, structural steel fabrication, and heavy equipment repair.

This specific configuration features a 10-foot cable assembly, providing a compact and manageable reach ideal for bench work, jig welding, or tight fabrication cells where excess cable length would be a hindrance. The gun comes pre-configured for 1/16-inch (1.6mm) welding wire, targeting heavy deposition applications often found in shipbuilding, railcar manufacturing, and heavy construction. The rear connection is a standard Tweco style, ensuring seamless compatibility with a vast array of wire feeders and power sources that utilize the industry-standard Tweco adapter.

Maintenance and inventory management are streamlined with the Spray Master series. It utilizes the widely available Tweco 11 Series contact tips, 52 Series gas diffusers, and 24 Series nozzles. The simplified consumable platform reduces the number of SKUs required in the tool crib. Furthermore, the gun features a fully serviceable design; the conductor tube, trigger assembly, and Cablehoz® can be replaced individually, extending the total service life of the asset and providing a lower total cost of ownership over time.

Constructed with high-grade copper components and high-impact resistant materials, the MS350 is built to withstand the rigors of harsh industrial environments. The metal-jacketed conductor tube is insulated to prevent electrical shorts, while the heavy-duty contact tip adapter ensures consistent current transfer for stable arc characteristics. For procurement managers and facility planners, the Tweco Spray Master represents a balance of performance, longevity, and consumable availability.
