10301006 - Tweco Classic 3 Velocity MIG Gun, 300A, 25ft, Tweco Connection

Industrial Grade 300A MIG Gun with Velocity Technology

The Tweco Classic No. 3 MIG Gun (SKU: 10301006) represents the evolution of one of the welding industry's most trusted tools. This model pairs the legendary ruggedness of the Classic series with the advanced performance of the Velocity™ consumable system. Rated for 300 Amps at a 60% duty cycle using CO2 gas, this air-cooled gun is engineered for medium to heavy-duty fabrication environments where reliability and uptime are critical. The "V3253545" configuration indicates a setup optimized for .035" to .045" wire diameters, making it versatile for structural steel, heavy equipment repair, and general manufacturing.

The standout feature of this assembly is the 25-foot cable length. While standard guns typically range from 10 to 15 feet, this extended reach allows operators to access large weldments without constantly moving the wire feeder or power source. This is particularly advantageous in shipyards, trailer manufacturing, and large-scale structural work. The cable itself is constructed with high-quality copper stranding and a durable outer jacket designed to resist cuts, abrasion, and burns from hot slag.

At the front end, the Velocity consumable platform revolutionizes arc performance. Unlike traditional threaded tips, Velocity tips feature a threadless, drop-in design that seats firmly into the conductor tube. This creates a solid copper-to-copper electrical path, significantly reducing electrical resistance and heat buildup. The result is a more stable arc, less spatter, and contact tips that last significantly longer than conventional designs. The gas nozzle also locks into place, ensuring concentric gas shielding and preventing the gas leaks common with threaded diffusers.

The rear of the gun features a standard Tweco-style connection, ensuring compatibility with a vast array of wire feeders from major brands like ESAB, Miller, and Lincoln (with appropriate adapters). The gun maintains the "Classic" oval handle shape that welders have favored for decades, providing a comfortable, balanced grip that reduces hand fatigue during long shifts. Maintenance is straightforward, with a fully field-repairable design that minimizes downtime.
