10201137 - Tweco Classic 2 MIG Gun, 200A, 10ft, Miller Plug, Velocity Series

Industrial Grade 200A MIG Gun with Velocity Technology

The Tweco Classic No. 2 MIG Gun (Part Number 1020-1137) represents a fusion of traditional durability and modern consumable technology. Designed for medium-duty industrial fabrication, this air-cooled gun is rated for 200 Amps at a 60% duty cycle when using CO2 shielding gas. It features a 10-foot cable assembly, making it ideal for bench work and standard fabrication cells where excessive cable length is unnecessary.

This specific configuration is engineered with a Miller-style rear connection, ensuring seamless integration with most Miller wire feeders and integrated MIG machines. The backend plug provides a secure gas and electrical connection, minimizing voltage drop at the feeder interface. The cable itself is constructed with high-quality copper stranding and a durable outer jacket resistant to cuts, abrasion, and mild spatter.

A key technical advantage of this model is the inclusion of the Velocity™ consumable series. Unlike traditional threaded tips, Velocity tips utilize a threadless, drop-in design that seats firmly into the gas diffuser. This creates a larger surface area for electrical contact and heat dissipation, resulting in a more stable arc and longer consumable life. The gas nozzle is also designed to optimize shielding gas flow, reducing turbulence and porosity risks. The gun comes pre-configured for .040" to .045" wire diameters, suitable for structural steel and general manufacturing applications.

The handle retains the ergonomic profile of the legendary Classic No. 2, known for its balance and comfort during extended welding shifts. The trigger mechanism is designed for reliability, rated for millions of cycles. Maintenance is simplified due to the reduced part count in the Velocity front-end assembly, allowing operators to change tips and nozzles rapidly without tools.
