The Tweco Classic No. 3 MIG Gun (Part Number 1030-1105) is widely recognized as the workhorse of the welding industry. Rated for 300 Amps at 60% duty cycle using CO2 gas, this air-cooled gun is engineered for high-volume manufacturing and fabrication environments where reliability is non-negotiable. This specific configuration features a generous 25-foot cable, providing welders with exceptional reach around large assemblies without moving the wire feeder.
At the core of its popularity is the Classic curved handle design. Developed decades ago, this ergonomic shape fits naturally in the welder's hand, reducing fatigue during long shifts and providing superior torch control. The gun comes set up for 0.035" to 0.045" wire, making it ready immediately for structural steel, heavy equipment repair, and general fabrication tasks. It utilizes the industry-standard Tweco back-end connection, ensuring compatibility with a vast range of wire feeders and power sources equipped with Tweco adapters.
Maintenance is a breeze with the Classic No. 3. It uses widely available Tweco consumables, including 14 Series contact tips, 23 or 24 Series nozzles, and 34/35 Series gas diffusers. The simplified design allows for quick liner changes and field repairs, minimizing downtime. The heavy-duty coaxial cable is resistant to cuts, abrasion, and heat, ensuring a long service life even on the roughest shop floors. Whether you are welding mild steel, stainless, or flux-cored applications, the Tweco Classic No. 3 delivers consistent arc performance and wire feeding.
