10401833 - Tweco SMV415-116 Spray Master V-Series MIG Gun 400A 15ft

Heavy-Duty Industrial MIG Gun

The Tweco 1040-1833 (Model SMV415-116) is a high-performance air-cooled MIG gun belonging to the renowned Spray Master V-Series. Engineered for demanding industrial environments, this torch is rated at 400 Amps (at 60% duty cycle) using CO2 gas, making it suitable for heavy fabrication, structural steel, and shipbuilding applications. The "V-Series" designation refers to the updated ergonomic handle design, which provides a more comfortable grip and better balance compared to traditional straight handles, significantly reducing operator fatigue during extended welding sessions.

This specific configuration comes equipped with a 15-foot (4.6-meter) cable assembly, offering substantial reach for working around large weldments. It is factory-setup to run 1/16-inch (1.6mm) welding wire, a standard diameter for high-deposition welding. The back-end connection is a standard Tweco style, ensuring seamless compatibility with a vast array of wire feeders and power sources that utilize the Tweco termination standard. The gun utilizes Tweco's industry-standard consumables, including the 11 Series contact tips and heavy-duty nozzles, which are widely available and easy to replace.

Maintenance of the SMV415-116 is straightforward due to its simplified design. The conductor tube can be rotated 360 degrees to access difficult joints, and the cable is constructed with high-quality copper stranding to ensure efficient current transfer and flexibility. The outer jacket is resistant to abrasion, cuts, and heat, ensuring longevity even in harsh shop conditions. For procurement and inventory management, this SKU represents a complete, ready-to-weld package (excluding wire) designed for 400A applications requiring 1/16" wire capability.
