10301010 - Tweco Classic 3 MIG Gun 300A 25ft 1/16 Velocity Series

Technical Overview of the Tweco Classic No. 3 Velocity MIG Gun

The Tweco Classic No. 3 (SKU: 10301010 / TWE1030-1010) represents a fusion of industry-standard durability and modern consumable technology. Rated for 300 Amps at a 60% duty cycle using CO2, this air-cooled MIG gun is engineered for medium to heavy-duty fabrication environments. This specific configuration is equipped with a 25-foot cable assembly, providing significant reach for large weldments, and is factory-setup for 1/16-inch (1.6 mm) welding wire, making it particularly suitable for structural flux-cored applications or heavy aluminum work.

A key technical differentiator is the integration of the Velocity™ consumable series. Unlike traditional threaded tips, Velocity contact tips utilize a threadless, drop-in design that maximizes surface contact for superior electrical conductivity and heat dissipation. This results in a more stable arc and extended consumable life. The gas nozzle features an integrated contact tip holder, simplifying the front-end assembly and reducing the number of replacement parts required. The gun terminates in a standard Tweco rear connection, ensuring broad compatibility with wire feeders utilizing the Tweco adapter standard.

The cable assembly is constructed with high-grade copper stranding and a durable outer jacket designed to withstand the rigors of industrial environments, including exposure to hot sparks, abrasion, and oils. The conductor tube is rotatable, allowing operators to adjust the angle for optimal access to difficult joints without straining the cable or the welder's wrist.
