The Tweco Classic No. 3 MIG Gun (Part Number 1030-1104) represents the gold standard in semi-automatic welding torches. Designed for heavy-duty industrial applications, this air-cooled gun is rated for 300 Amps at a 60% duty cycle when using CO2 shielding gas. It is engineered to withstand harsh manufacturing environments while delivering consistent arc performance.
This specific configuration features a 20-foot cable assembly, providing significant reach for welders working on large structures or in bays where the power source is stationary. The gun comes factory-ready for .035" to .045" (0.9mm - 1.2mm) welding wire, making it versatile for structural steel, fabrication, and repair work. The rear connection is the standard Tweco style, ensuring compatibility with a vast range of wire feeders and power sources that utilize the Tweco adapter system.
Maintenance is straightforward with the Classic No. 3. It utilizes the widely available 14 Series contact tips, 23 or 24 Series gas nozzles, and 34 Series gas diffusers. The simplified design allows for quick consumable changes and liner replacements, minimizing downtime. The metal-jacketed conductor tube adds rigidity and heat resistance, while the heavy-duty cable resists cuts and abrasion.
