244130 - Miller 244130 Replacement Cooling Fan 12VDC 110 CFM

Miller 244130 Muffin Fan Technical Overview

The Miller 244130 is a specialized muffin fan designed for thermal management within Miller welding power sources. As a genuine OEM component, it is engineered to meet the specific electrical and mechanical requirements of Miller equipment, ensuring reliable operation and longevity. This unit operates on a 12 VDC input, making it compatible with the low-voltage control circuits found in modern inverter-based welding machines.

Performance-wise, the fan rotates at a high speed of 4800 RPM. This rapid rotation allows it to move a significant volume of air, rated at 110 CFM (Cubic Feet per Minute). This high airflow is critical for dissipating heat generated by power transistors, transformers, and rectifiers during the welding process. Proper cooling is essential to prevent thermal overload shutdowns and to maintain the machine's duty cycle, particularly during heavy industrial use.

The physical construction is a standard muffin fan form factor, designed to fit specific mounting points inside the welder chassis. It comes equipped with leads, facilitating a direct connection to the machine's internal wiring harness without the need for complex soldering or connector fabrication in the field. Technicians repairing Miller equipment should verify the part number 244130 to ensure voltage and dimensional compatibility before installation.

Using non-OEM fans with incorrect CFM ratings or amperage draw can lead to insufficient cooling or damage to the fan control board. The Miller 244130 ensures that the cooling profile matches the original engineering design of the welding power source.
