Tweco Classic No. 1 MIG Gun - 180 Amp, 10 ft, Miller Connection

The Tweco Classic No. 1 MIG Gun (SKU: 10101131) represents the gold standard in air-cooled MIG welding torches for light to medium-duty applications. Renowned for its durability and simplicity, the Classic No. 1 has been a staple in fabrication shops for decades. This specific configuration is rated for 180 Amps at a 60% duty cycle when using CO2 gas, making it an ideal choice for automotive repair, sheet metal fabrication, and general maintenance welding. The gun comes equipped with a 10-foot cable assembly, providing sufficient reach for bench work and smaller welding cells without the clutter of excess cable.

Designed for seamless integration, this model features a Miller-style back-end connection, allowing it to plug directly into most Miller wire feeders and compact MIG machines without the need for adapters. The gun is pre-configured for .030" to .035" (0.8mm - 0.9mm) welding wire, covering the most common wire diameters used in its amperage class. At the front end, it utilizes the widely available Tweco 11 Series contact tips and 21 Series gas nozzles, ensuring that replacement consumables are affordable and easy to source from virtually any welding supplier.

The construction of the Tweco Classic No. 1 is built around the operator. It features the signature Tweco paddle switch handle, which reduces hand fatigue during extended welding sessions compared to trigger-style switches. The conductor tube is mechanically fastened to the cable, ensuring a solid electrical connection that resists overheating. Furthermore, the cable itself is protected by heavy-duty steel spring strain reliefs at both the handle and the feeder connection, preventing kinking and extending the service life of the liner and power cable. For professionals seeking a reliable, field-repairable MIG gun that fits their Miller equipment, the Tweco Classic No. 1 is the proven solution.
