10361752 - Tweco Spray Master V350 MIG Gun, 350A, 12ft, 1/16 Wire, Tweco Connection

High-Performance 350A MIG Gun with Velocity Technology

The Tweco Spray Master V350 MIG Gun (Part Number 1036-1752) represents a significant evolution in air-cooled welding torch technology, specifically engineered to address the rigorous demands of high-amperage industrial fabrication. At the core of this system is the proprietary Velocity™ consumable platform. Traditional MIG guns rely on threaded contact tips which can loosen over time, creating electrical resistance and heat buildup—the primary causes of premature tip failure and arc instability. The Velocity system eliminates this weak point by utilizing a threadless, drop-in contact tip design. The tip is seated firmly into the gas diffuser and secured by the nozzle, establishing a large surface area of contact. This "solid copper path" optimizes electrical conductivity and thermal transfer, keeping the consumables significantly cooler even during extended weld cycles at high amperages.

Rated for 350 Amps at an 80% duty cycle using CO2 shielding gas, the V350 is a workhorse for structural steel, heavy equipment manufacturing, and general fabrication. This specific configuration (SMV312-116) is equipped with a 12-foot cable assembly and is factory-fitted for 1/16-inch (1.6mm) welding wire, making it an immediate solution for heavy-deposition applications such as flux-cored arc welding (FCAW) or heavy-plate MIG welding. The rear connection utilizes the industry-standard Tweco style termination, ensuring compatibility with a vast array of wire feeders and power sources.

Beyond the consumables, the Spray Master V350 retains the legendary ergonomic handle design that has made the Spray Master series a favorite among professional welders. The handle is constructed from high-impact, glass-reinforced composite material, offering exceptional durability in harsh shop environments. The conductor tube rotates 360 degrees, allowing welders to adjust the gun angle for optimal access to difficult joints without straining their wrists. The cable assembly features a heavy-duty outer jacket that resists cuts, abrasion, and burns, protecting the internal copper stranding and liner. Maintenance is simplified with the Velocity system, as fewer parts are required, and change-outs are faster, reducing downtime and increasing overall productivity.
