10361647 - Tweco Spray Master MS350 MIG Gun, 350A, 15ft, Lincoln Plug, 1/16 Wire

Technical Specifications: Tweco 1036-1647 Spray Master MS350

The Tweco Spray Master MS350 (Model MS315L116) is a premium air-cooled MIG gun designed for high-amperage MIG (GMAW) and Flux-Cored (FCAW) welding applications. This unit is rated for 350 Amps at 80% duty cycle using CO2 shielding gas, providing a robust solution for industrial fabrication environments. The gun features a 15-foot (4.5m) cable assembly that balances flexibility with durability, utilizing high-quality copper stranding to ensure efficient current transfer and minimal voltage drop over the length of the lead.

A key feature of this configuration is the Lincoln-style rear connection, allowing for direct plug-and-play compatibility with Lincoln Electric wire feeders that utilize the standard Lincoln gun receiver. The gun is factory-setup with a liner and contact tip for 1/16" (1.6mm) welding wire, targeting heavy-deposition applications. The front-end consumables are based on the proven Tweco platform:

• Contact Tips: Uses 11-Series heavy-duty tips, known for their excellent electrical conductivity and wear resistance.
• Nozzles: Compatible with 22-Series adjustable nozzles, allowing operators to fine-tune the contact tip recess for optimal gas coverage.
• Diffusers: Utilizes 52-Series gas diffusers to ensure laminar gas flow and protect the weld pool from atmospheric contamination.

The conductor tube (gooseneck) is rotatable, allowing the welder to adjust the angle for better access into tight joints or difficult positions. The cable hose is constructed from abrasion-resistant materials to withstand the rigors of the shop floor, including exposure to hot sparks and rough surfaces. The simplified design of the Spray Master series reduces the number of replacement parts required, lowering overall inventory costs and simplifying maintenance procedures. For professionals seeking a 350A class gun that integrates seamlessly with Lincoln power sources while offering the superior consumable life of Tweco, the MS350 is the optimal choice.
