10301007 - Tweco Classic No. 3 MIG Gun, 300A, 20ft, Velocity Consumables, Tweco Connection

Legendary Performance Meets Modern Efficiency

The Tweco Classic No. 3 MIG Gun has long been the standard-bearer for industrial welding, trusted by fabricators worldwide for its rugged durability and ergonomic design. This specific configuration (SKU: 10301007) elevates that legacy by integrating Tweco's advanced Velocity™ consumable system. Designed for professional welders who demand reliability, this 300-amp air-cooled gun is built to withstand the harshest shop environments while delivering a smooth, consistent arc.

Extended Reach and Durability

With a generous 20-foot (6.1 meter) cable, this MIG gun provides the freedom to move around large assemblies and fixtures without constantly repositioning the wire feeder. The cable itself is constructed with high-grade copper stranding and a tough outer jacket that resists abrasion, cuts, and burns, ensuring a long service life even in heavy structural steel or manufacturing settings. The classic curved handle offers a natural grip that reduces operator fatigue during long welding shifts.

Velocity Consumable Advantage

What sets this model apart is the inclusion of Velocity consumables. Unlike traditional front-end parts, Velocity tips and nozzles feature a threadless, drop-in design or coarse threads that resist seizing. This system optimizes electrical conductivity and heat dissipation, keeping the contact tip cooler and extending its lifespan. The result is fewer consumable changes, less downtime, and a more stable arc. The gun comes set up for 0.035" to 0.045" wire, making it ready for the most common steel fabrication tasks right out of the box.

Universal Compatibility

This unit features a standard Tweco-style rear connection, making it compatible with a vast array of wire feeders and power sources from major brands like ESAB, Lincoln, and Miller (with adapters or native Tweco drives). Whether you are welding mild steel, stainless, or flux-cored applications, the Tweco Classic No. 3 delivers the power and precision needed for high-quality welds.
