300956 - Miller Industrial Dual MIG Connection Kit with 4/0 Cables and Regulators

Comprehensive Connectivity for Dual Wire Feeders

The Miller 300956 Industrial Dual MIG 4/0 Kit is a premium accessory package designed specifically to facilitate the setup and operation of industrial dual wire feeders. In high-production welding environments, reliability and capacity are paramount. This kit addresses both by providing heavy-duty power transmission components alongside precision gas regulation equipment, all in a single, convenient package. By bundling these essential components, Miller ensures that welding operators have the correctly rated equipment to handle the high duty cycles and amperages often associated with dual feeder applications.

Heavy-Duty Power Transmission

At the core of this kit are the 4/0 AWG welding cables. Rated for high amperage, these cables are essential for industrial MIG welding where voltage drop and overheating must be minimized to maintain arc stability and weld quality. The cables measure 10 feet (3 meters) in length, offering a standard reach suitable for most stationary or boom-mounted feeder setups. Each cable is terminated with Dinse-style connectors. Dinse connectors are the industry standard for modern welding power sources, offering a twist-lock mechanism that ensures a tight, high-conductivity connection that resists loosening during operation. This secure connection helps prevent arcing at the terminal, protecting both the machine and the cable.

Precision Gas Control

Dual wire feeders allow welders to switch between two different wire types—such as steel and aluminum, or two different diameters—without changing spools. This requires two separate shielding gas supplies. The Miller 300956 kit includes two Miller | Smith regulator/flowmeters. Smith is renowned for manufacturing some of the most accurate and durable gas equipment in the industry. These flowmeters allow for precise adjustment of shielding gas flow rates, which is critical for preventing porosity and ensuring a clean weld bead. Accompanying the regulators are two 10-foot (3 meter) gas hoses, completing the gas delivery system from cylinder to feeder.

Streamlined Installation

Sourcing individual cables, connectors, and regulators can be time-consuming and risks compatibility issues. This kit eliminates the guesswork by providing matched components guaranteed to fit Miller industrial equipment with Dinse outputs. Whether setting up a new shop or upgrading existing power sources, the Miller 300956 kit provides a professional, ready-to-install solution that meets the rigorous demands of industrial manufacturing.
