OVERVIEW

High-Performance Replacement MIG Torch - 300A, 15ft

The RM3015-116 MIG Gun is a premium-quality aftermarket torch designed to meet the rigorous demands of professional welders. Modeled after the popular Tregaskiss style, this gun combines rugged construction with ergonomic features to provide a superior welding experience. It is specifically outfitted with a Miller back-end connection, making it a direct replacement for worn-out guns on Miller wire feeders and welding machines.

Performance-wise, this torch is a workhorse. It is rated for 300 Amps at 100% duty cycle with CO2, and 250 Amps with mixed gases, ensuring it can withstand the heat of prolonged welding sessions. The 15-foot cable assembly is reinforced to resist abrasion and cutting, common hazards in busy workshops. This specific model is set up for 1/16-inch welding wire, ideal for structural applications and heavy plate welding where higher deposition rates are required.

Maintenance is straightforward thanks to the use of industry-standard Tregaskiss-style consumables. The nozzle, contact tip, and diffuser are easy to change and widely available, ensuring you are never stuck waiting for proprietary parts. The gun features a comfortable, curved handle that provides excellent grip and control, helping to improve weld quality by reducing operator fatigue. Whether you are in manufacturing, repair, or construction, this 300A MIG gun offers the reliability and performance needed to get the job done efficiently.
