10101125 - Tweco Classic 1 MIG Gun - 180A, 10ft, Miller Style

Reliable Performance with the Tweco Classic No. 1 MIG Gun

The Tweco Classic No. 1 MIG Gun (SKU: 1010-1125) represents the heritage of quality and reliability that welders have trusted for decades. Designed for light-to-medium duty fabrication, this air-cooled gun is rated at 180 Amps at a 60% duty cycle using CO2 gas, making it an excellent choice for automotive repair, farm equipment maintenance, and general hobbyist welding. This specific model comes equipped with a Miller-style backend connection, ensuring seamless plug-and-play compatibility with a wide range of Miller wire feeders and integrated MIG machines.

One of the standout features of the Classic No. 1 is its ergonomic handle. The design has been refined over years of field use to provide a comfortable grip that reduces operator fatigue during long welding sessions. The 10-foot cable assembly offers sufficient reach for bench work and smaller shop environments without the hassle of managing excessive cable slack. The cable itself is constructed with high-quality copper stranding and a durable outer jacket that resists cuts, abrasion, and heat, ensuring a long service life even in tough workshop conditions.

Maintenance is straightforward with the Tweco Classic series. The gun utilizes the widely available 11 Series contact tips, 21 Series nozzles, and 31 Series gas diffusers. These consumables are stocked in almost every welding supply shop, meaning you will never be left stranded waiting for parts. The mechanical connection between the conductor tube and the cable is designed to be field-repairable, allowing you to extend the life of the gun significantly compared to disposable alternatives. Whether you are welding mild steel, stainless, or aluminum (with a liner change), the Tweco Classic No. 1 delivers consistent arc performance and smooth wire feeding.
