10001213 - Tweco Mini-Mig Gun 12ft for Miller Welders

Professional Grade Replacement MIG Gun

The Tweco Mini-Mig M3512-12FT-MIL (1000-1213) is a high-quality replacement MIG gun engineered to provide superior performance and durability for Miller welding machines. Designed as a direct replacement for stock guns on compact and medium-duty wire feeders, this unit features a Miller-style backend connection, ensuring a seamless plug-and-play installation without the need for adapters.

With a 12-foot cable length, this gun offers extended reach, allowing welders to move freely around large automotive projects or fabrication tables without dragging the power source. The cable is constructed with Tweco's signature quality, providing excellent flexibility and resistance to kinking, which is critical for maintaining smooth wire feeding and consistent arc stability.

Ergonomics and Maintenance

The Mini-Mig series is renowned for its ergonomic handle design, which fits naturally in the hand to reduce fatigue during long welding sessions. The trigger action is smooth and reliable, offering precise control over the arc. Maintenance is simplified thanks to the use of standard Tweco Mini-Mig consumables, including 11 Series contact tips and 21 Series gas nozzles. These parts are widely available and cost-effective, making this gun an economical choice for both professional shops and serious hobbyists.

Applications

This gun is perfectly suited for light-to-medium duty applications, including automotive body work, light fabrication, farm repair, and maintenance operations. It comes set up for standard wire diameters (typically .030" - .035"), making it ready to tackle mild steel, stainless, and flux-cored welding tasks immediately out of the box.
