284973 - Hobart HR200 15ft MIG Gun Replacement for IronMan 240 & Miller M-25

Technical Overview of the Hobart HR200 MIG Gun

The Hobart HR200 MIG Gun (SKU: 284973) is a high-performance welding assembly designed to meet the rigorous demands of light industrial and general fabrication environments. Engineered as a genuine replacement component for the Hobart IronMan 240 MIG welder, this gun ensures seamless integration with the power source's wire drive system. Furthermore, the HR200 is manufactured to be a direct functional replacement for the Miller M-25 MIG gun, providing versatility for shops that utilize Miller-style equipment. The gun is rated for a welding output of 200 amps at a 60% duty cycle, making it capable of sustained operation during extended welding passes on mild steel, stainless steel, and aluminum applications.

The assembly features a 15-foot cable, offering significant operational reach that allows welders to navigate around large workpieces without constantly repositioning the power source. The cable is reinforced with heavy-duty strain reliefs at both the feeder connection and the gun handle, which protects the internal copper cabling and gas hose from mechanical stress and kinking. This design consideration significantly extends the service life of the gun in dynamic workshop settings. The HR200 comes pre-configured for .030-inch to .035-inch wire diameters, covering the most common range for general fabrication and automotive repair tasks.

Technically, the gun supports both 100% CO2 and C25 (75% Argon / 25% CO2) shielding gases, ensuring stable arc characteristics across different welding modes. The front-end consumables—including the nozzle, contact tip, and gas diffuser—are standard industry sizes, simplifying inventory management for maintenance departments. The connection pin configuration is designed for standard Miller/Hobart back-ends, ensuring a secure electrical and gas connection. By utilizing the HR200, operators can maintain the original performance specifications of their welding equipment, ensuring consistent wire feed speeds and optimal arc stability.
