RM3015-116 - 300A MIG Gun, Tregaskiss Style, 15ft, Miller Connection, 1/16" Wire

Reliable 300A MIG Gun for Heavy-Duty Welding

Upgrade your welding operations with this robust 300 Amp Tregaskiss-style MIG Gun, designed to deliver consistent performance in demanding industrial environments. Engineered for durability and ease of use, this air-cooled torch is an excellent replacement or upgrade for welders using Miller wire feeders. With a generous 15-foot cable length, it provides the reach necessary for working on large assemblies, structural steel, and fabrication projects without constantly moving the power source.

This gun is built to handle high-amperage applications, boasting a 100% duty cycle at 300 Amps when using CO2 shielding gas, and 250 Amps with mixed gas. It comes pre-configured with a liner and contact tip for 1/16" (1.6mm) wire, making it ready for heavy deposition welding right out of the box. The Miller direct connection ensures a secure and hassle-free setup with compatible Miller machines, eliminating the need for adapters.

One of the key advantages of this torch is its compatibility with standard Tregaskiss-style consumables. This means you can easily source replacement contact tips, nozzles, and gas diffusers from a wide variety of suppliers, keeping your operating costs low and your downtime minimal. The ergonomic handle design reduces hand stress during long welding shifts, while the heavy-duty spring strain reliefs protect the cable from kinking and wear at connection points.
